 This is a Progressive Web App, so you can also "install" it to your Android or iOS device by accessing it in Chrome or
 Safari respectively, and following the menu-driven process for installing PWAs.

-You are more than welcome to use the data and the API that Spothole provides to power your own software. There are many
-ways to do this; see below.
-
-## Embedding Spothole in another website
-
-You can embed Spothole's web interface in another website, e.g. for use as part of a ham radio custom dashboard.
-
-URL parameters can be used to trigger an "embedded" mode which hides the headers, footers and settings. In this mode,
-you provide configuration for the various filter and display options via additional URL parameters. Any settings that
-the user has set for Spothole are ignored. This is so that the embedding site can select, for example, their choice of
-dark mode or SIG filters, which will not impact how Spothole appears when the user accesses it directly. Effectively, it
-becomes separate to their normal Spothole settings.
-
-Setting `embedded` to true is important for the rest of the settings to be applied; otherwise, the user's defaults will
-be used in preference to the URL params.
-
-These are supplied with the URL to the page you want to embed, for example for an embedded version of the band map in
-dark mode, use `https://spothole.app/bands?embedded=true&dark-mode=true`. For an embedded version of the main spots/home
-page in the system light/dark mode, use `https://spothole.app/?embedded=true`. For dark mode showing 70cm TOTA spots
-only, use `https://spothole.app/?embedded=true&dark-mode=true&sig=TOTA&band=70cm`. Providing no URL params causes the
-page to be loaded in the normal way it would when accessed directly in the user's browser.
-
-The supported parameters are as follows. Generally these match the equivalent parameters in the real Spothole API, where
-a mapping exists.

-## Writing your own client
-
-One of the key strengths of Spothole is that the API is well-defined and open to anyone to use. This means you can build
-your own software that uses data from Spothole.
-
-As well as the main API endpoints to fetch spots and alerts, with various possible query parameters, there are also
-Server-Sent Events (SSE) API endpoints to receive a live feed, plus various utility lookup endpoints for things like
-callsign and park data.
-
-Various approaches exist to writing your own client, but in general:
-
-* Refer to the API docs. These are built on an OpenAPI definition file (`/webassets/apidocs/openapi.yml`), which you can
-  automatically use to generate a client skeleton using various software.
-* Call the main "spots" or "alerts" API endpoints to get the data you want. For example, your app could call
-  `https://spothole.app/api/v1/spots` once every few minutes. Apply filters if necessary.
-* Call the "options" API to get an idea of which bands, modes etc. the server knows about. You might want to do that
-  first before calling the spots/alerts APIs, to allow you to populate your filters correctly.
-* Refer to the provided HTML/JS interface for a reference on different approaches. For example, the "map" and "bands"
-  pages simply query the main spot API on a timer, whereas the main/spots page combines this approach with using the
-  Server-Sent Events (SSE) endpoint to update live.
-* Let me know if you get stuck, I'm happy to help.
-
-Please don't hammer the API with an unnecessarily high request rate. For example, Spothole only queries the POTA API
-once every two minutes, so if your client is interested in POTA data there's no need to poll Spothole any more often
-than that.
-
-If you absolutely must be informed within seconds of a spot arriving in Spothole, please use the SSE endpoints instead,
-e.g. `https://spothole.app/api/v1/spots/stream`.
-
-If you want to handle different types of spot or alert differently within your client, please consider making a single
-request to the Spothole API to retrieve all the data, then filtering on your side. For example, call
-`https://spothole.app/api/v1/spots?sig=POTA,SOTA` rather than making two separate calls to
-`https://spothole.app/api/v1/spots?sig=POTA` and `https://spothole.app/api/v1/spots?sig=SOTA`.
-
-Remember, here at Spothole Inc. we offer an industry-standard "five nines" uptime on our server, with our own unique
-twist: we don't tell you which side of the decimal point the nines start! (Translation: This is a hobby project.
-`spothole.app` runs on the same server as my blog and other stuff. It might go down without warning. By all means base
-your own project on data from the main server if you like, but if you want any control over reliability and downtime,
-please run your own copy instead.)
-
-## Running your own copy
-
-If you want to run a copy of Spothole with different configuration settings than the main instance, you can download it
-and run it on your own local machine or server.
-
-You will require Python version 3.8 or later. If you encounter an error about `gdal-config` during the following
-process, you will also need `libgdal-dev` installed.
-
-To download and set up Spothole on a Debian server, run the following commands. Other operating systems will likely be
-similar.
-
-```bash
-git clone ssh://git@git.ianrenton.com/ian/spothole.git
-cd spothole
-python3 -m venv ./.venv
-source .venv/bin/activate
-pip install -r requirements.txt
-deactivate
-cp config-example.yml config.yml
-```
-
-Then edit `config.yml` in your text editor of choice to set up the software as you like it. Mostly, this will involve
-enabling or disabling the various providers of spot and alert data.
-
-By default, all outdoor programme providers are enabled, as is one cluster node and the NG3K DXpedition data. The RBN
-spot providers are turned off by default due to the volume of traffic from CW/RTTY/FT8 skimmers, and the APRS and Packet
-spot providers are off by default on the assumption that Spothole users want a spot with a human at the other end of it,
-but all can be easily re-enabled.
-
-Other parameters you will want to update include the base URL to your instance, and whether you want to serve a full
-web-based DX cluster interface or just the API endpoints for client software to use.
-
-`config.yml` has an entry for a Clublog API key. If provided, this will allow Spothole to retrieve some more information
-about DX spots. The software will work just fine without it, but you may find a few country flags etc. are less accurate
-or missing. Clublog API keys are free, but you'll need to get your own by submitting a helpdesk ticket and explaining
-what you'll use it for. The admin team are happy with the rate of requests made by my Spothole server, so unless you
-change the source code of yours to radically increase the rate of querying Clublog, I'm sure they will be fine with your
-server too.
-
-Once you're happy with the content of `config.yml`, you can proceed to running the software.
-
-To run the software this time and any future times you want to run it directly from the command line:
-
-```bash
-source .venv/bin/activate
-python3 spothole.py
-```
-
-The software can take a few seconds to start up, mostly because it is downloading an updated file to match callsigns to
-countries. This is normal, don't panic!
-
-If you see some errors on startup, check your configuration, e.g. in case you have specified a port for the web server
-that is already in use by something else.
-
-### Multiple cluster nodes with different settings
-
-Dan, S50U has written in with his Spothole cluster settings. He is using a cluster node which provides RBN spots, and
-uses different SSIDs on his callsign to get different settings when logged into the same cluster node. For example:
-
-```
-  -
-    class: "DXCluster"
-    name: "S50CLX"
-    enabled: true
-    host: "s50clx.si"
-    port: 41112
-    login_prompt: "login: "
-    login_callsign: "callsign-10"
-```
-
-Telnet to DXSpider and log in with "callsign-10" and execute the following commands:
-
-`CLEAR/SPOTS ALL` (delete all previous filters)<br/>
-`UNSET/ANN` (stop announce messages)<br/>
-`UNSET/WCY` (stop wcy messages)<br/>
-`UNSET/WWV` (stop wwv messages)<br/>
-`SET/DX` (enable human DX spots)
-
-```
-  -
-    class: "DXCluster"
-    name: "RBN CW"
-    enabled: true
-    host: "s50clx.si"
-    port: 41112
-    login_prompt: "login: "
-    login_callsign: "callsign-11"
-    allow_rbn_spots: true
-    enabled-by-default-in-web-ui: false
-```
-
-Telnet to DXSpider and log in with "callsign-11" and execute the following commands:
-
-`CLEAR/SPOTS ALL` (delete all previous filters)<br/>
-`UNSET/ANN` (stop announce messages)<br/>
-`UNSET/WCY` (stop wcy messages)<br/>
-`UNSET/WWV` (stop wwv messages)<br/>
-`UNSET/DX` (stop human DX spots)<br/>
-`SET/SKIMMER CW` (enable CW RBN spots)
-
-```
-  -
-    class: "DXCluster"
-    name: "RBN RTTY"
-    enabled: true
-    host: "s50clx.si"
-    port: 41112
-    login_prompt: "login: "
-    login_callsign: "callsign-12"
-    allow_rbn_spots: true
-    enabled-by-default-in-web-ui: false
-```
-
-Telnet to DXSpider and log in with "callsign-12" and execute the following commands:
-
-`CLEAR/SPOTS ALL` (delete all previous filters)<br/>
-`UNSET/ANN` (stop announce messages)<br/>
-`UNSET/WCY` (stop wcy messages)<br/>
-`UNSET/WWV` (stop wwv messages)<br/>
-`UNSET/DX` (stop human DX spots)<br/>
-`SET/SKIMMER RTTY` (enable RTTY RBN spots)
-
-```
-  -
-    class: "DXCluster"
-    name: "RBN FT4/8"
-    enabled: true
-    host: "s50clx.si"
-    port: 41112
-    login_prompt: "login: "
-    login_callsign: "callsign-13"
-    allow_rbn_spots: true
-    enabled-by-default-in-web-ui: false
-```
-
-Telnet to DXSpider and log in with "callsign-13" and execute the following commands:
-
-`CLEAR/SPOTS ALL` (delete all previous filters)<br/>
-`UNSET/ANN` (stop announce messages)<br/>
-`UNSET/WCY` (stop wcy messages)<br/>
-`UNSET/WWV` (stop wwv messages)<br/>
-`UNSET/DX` (stop human DX spots)<br/>
-`SET/SKIMMER FT` (enable FT RBN spots)
-
-For each callsign-SSID, we also specify our basic information with commands:
-
-`SET/NAME Spothole10`, Spothole11... etc.<br/>
-`SET/QTH Cerkno`<br/>
-`SET/QRA JN66XD`<br/>
-`SET/HOME S50CLX`
-
-### systemd configuration
-
-If you want Spothole to run automatically on startup on a Linux distribution that uses `systemd`, follow the
-instructions here. For distros that don't use `systemd`, or Windows/OSX/etc., you can find generic instructions for your
-OS online.
-
-Create a file at `/etc/systemd/system/spothole.service`. Give it the following content, adjusting for the user you want
-to run it as and the directory in which you have installed it:
-
-```
-[Unit]
-Description=Spothole
-After=syslog.target network.target
-
-[Service]
-Type=simple
-User=spothole
-WorkingDirectory=/home/spothole/spothole
-ExecStart=/home/spothole/spothole/.venv/bin/python /home/spothole/spothole/spothole.py --serve-in-foreground
-Restart=on-abort
-
-[Install]
-WantedBy=multi-user.target
-```
-
-Run the following:
-
-```bash
-sudo systemctl daemon-reload
-sudo systemctl enable spothole
-sudo systemctl start spothole
-```
-
-Check the service has started up correctly with `sudo journalctl -u spothole -f`.
-
-### nginx Reverse Proxy configuration
-
-Web servers generally serve their pages from port 80. However, it's best not to serve Spothole's web interface directly
-on port 80, as that requires root privileges on a Linux system. It also and prevents us using HTTPS to serve a secure
-site, since Spothole itself doesn't directly support acting as an HTTPS server. The normal solution to this is to use
-a "reverse proxy" setup, where a general web server handles HTTP and HTTP requests (to port 80 & 443 respectively), then
-passes on the request to the back-end application (in this case Spothole). nginx is a common choice for this general web
-server.
-
-To set up nginx as a reverse proxy that sits in front of Spothole, first ensure it's installed e.g.
-`sudo apt install nginx`, and enabled e.g. `sudo systemd enable nginx`.
-
-Create a file at `/etc/nginx/sites-available/` called `spothole`. Give it the following contents, replacing
-`spothole.app` with the domain name on which you want to run Spothole. If you changed the port on which Spothole runs,
-update that on the "proxy_pass" line too.
-
-```nginx

-    server_name spothole.app;

-One further change you might want to make to the file above is the `add_header Access-Control-Allow-Origin` statements.
-These are what's used on
-my own Spothole server to make sure that other third-party web-based software can get the data from my instance, and
-applies to any endpoint underneath `/api`. If you want
-*your* Spothole instance to be set up the same way, so that others can write software in JavaScript that can access it,
-leave this intact. But if you want your Spothole instance to only be usable by scripts running on the web server you
-write,
-you can remove these lines. (Note that this doesn't stop other people writing *non-web-based* software that accesses
-your
-Spothole API&mdash;the enforcement of cross-origin headers only happens within the user's browser. If you need to lock
-your
-instance down so that no-one else can access it with *any* software, that's an aspect of nginx or firewall config that
-you will need
-to find help with elsewhere.)
-
-Now, make a symbolic link to enable the site:
-
-```bash
-cd /etc/nginx/sites-enabled
-sudo ln -sf ../sites-available/spothole
-```
-
-Test that your nginx config isn't broken using `nginx -t`. If it works, restart nginx with
-`sudo systemctl restart nginx`.
-
-If you haven't already done so, set up a DNS entry to make sure requests for your domain name end up at the server
-that's running Spothole.
-
-You should now be able to access the web interface by going to the domain from your browser.
-
-Once that's working, [install certbot](https://certbot.eff.org/instructions?ws=nginx&os=snap) onto your server. Run it
-as root, and when prompted pick your domain name from the list. After a few seconds, it should successfully provision a
-certificate and modify your nginx config files automatically. You should then be able to access the site via HTTPS.

-## Modifying the source code
-
-Spothole is Public Domain licenced, so you can grab the source code and start modifying it for your own needs.
-Contributions of code back to the main repository are encouraged, but completely optional.
-
-### Code structure
-
-To navigate your way around the source code, this list may help.
-
-*Python back-end code*
-
-* `/core` - Core classes and scripts
-* `/data` - Data storage classes
-* `/spotproviders` - Classes providing spots by accessing the APIs of other services
-* `/alertproviders` - Classes providing alerts by accessing the APIs of other services
-* `/solarconditionsproviders` - Classes providing solar and propagation by accessing the APIs of other services
-* `/server` - Classes for running Spothole's own web server
-
-*Templates*
-
-* `/templates` - Templates used for constructing Spothole's user-targeted HTML pages
-
-*HTML/JS/CSS front-end code*
-
-* `/webassets` - Root for static files served by the web server
-* `/webassets/apidocs` - Contains the OpenAPI spec (`openapi.yml`)
-* `/webassets/css` - CSS files used by the web front-end
-* `/webassets/img` - image files used by the web front-end
-* `/webassets/js` - JavaScript used by the web front-end
-* `/webassets/vendor` - Third-party libraries (CSS, JS, fonts and images)
-
-*Miscellaneous*
-
-* `/` - Main script (`spothole.py`), pip `requirements.txt`, config, README, etc.
-* `/images` - Image sources
-* `/datafiles` - Local data sources (differentiated from the majority of data files which are loaded from URLs and
-  cached in `/cache`)
-* `/cache` - Directory where static-ish data downloaded from the internet is cached to avoid rapid re-requests, and
-  where spot/alert data is cached so that it survives a software restart. Created on first run.
-
-### Extending the server
-
-Spothole is designed to be easily extensible. If you want to write your own spot provider, for example, simply add a
-module to the `spotproviders` package containing your class. (Currently, in order to be loaded correctly, the module (
-file) name should be the same as the class name, but lower case.)
-
-Your class should extend "SpotProvider"; if it operates by polling an HTTP Server on a timer, it can instead extend "
-HTTPSpotProvider" where some of the work is done for you.
-
-The class will need to implement a constructor that takes in the `provider_config` and provides it to the superclass
-constructor, while also taking any other config parameters it needs.
-
-If you're extending the base `SpotProvider` class, you will need to implement `start()` and `stop()` methods that start
-and stop a separate thread which handles the provider's processing needs. The thread should call `submit()` or
-`submit_batch()` when it has one or more spots to report.
-
-If you're extending the `HTTPSpotProvider` class, you will need to provide a URI to query and an interval to the
-superclass constructor. You'll then need to implement the `http_response_to_spots()` method which is called when new
-data is retrieved. Your implementation should then call `submit()` or `submit_batch()` when it has one or more spots to
-report.
-
-When constructing spots, use the comments in the Spot class and the existing implementations as an example. All
-parameters are optional, but you will at least want to provide a `time` (which must be timezone-aware) and a `dx_call`.
-
-Finally, simply add the appropriate config to the `spot_providers` section of `config.yml`, and your provider should be
-instantiated on startup.
-
-The same approach as above is also used for alert providers.

 ## Thanks

 As well as being my work, I have also gratefully received feature patches from Steven, M1SDH.

+## Writing your own client
+
+One of the key strengths of Spothole is that the API is well-defined and open to anyone to use. This means you can build
+your own software that uses data from Spothole.
+
+As well as the main API endpoints to fetch spots and alerts, with various possible query parameters, there are also
+Server-Sent Events (SSE) API endpoints to receive a live feed, plus various utility lookup endpoints for things like
+callsign and park data.
+
+Various approaches exist to writing your own client, but in general:
+
+* Refer to the API docs. These are built on an OpenAPI definition file (`/static/apidocs/openapi.yml`), which you can
+  automatically use to generate a client skeleton using various software.
+* Call the main "spots" or "alerts" API endpoints to get the data you want. For example, your app could call
+  `https://spothole.app/api/v1/spots` once every few minutes. Apply filters if necessary.
+* Call the "options" API to get an idea of which bands, modes etc. the server knows about. You might want to do that
+  first before calling the spots/alerts APIs, to allow you to populate your filters correctly.
+* Refer to the provided HTML/JS interface for a reference on different approaches. For example, the "alerts"/"upcoming"
+  page simply query the main spot API on a timer, whereas the spots, map and bands pages combine this approach with
+  using the Server-Sent Events (SSE) endpoint to update live.
+* Let me know if you get stuck, I'm happy to help.
+
+Please don't hammer the API with an unnecessarily high request rate. For example, Spothole only queries the POTA API
+once every two minutes, so if your client is interested in POTA data there's no need to poll Spothole any more often
+than that.
+
+If you absolutely must be informed within seconds of a spot arriving in Spothole, please use the SSE endpoints instead,
+e.g. `https://spothole.app/api/v1/spots/stream`.
+
+If you want to handle different types of spot or alert differently within your client, please consider making a single
+request to the Spothole API to retrieve all the data, then filtering on your side. For example, call
+`https://spothole.app/api/v1/spots?sig=POTA,SOTA` rather than making two separate calls to
+`https://spothole.app/api/v1/spots?sig=POTA` and `https://spothole.app/api/v1/spots?sig=SOTA`.
+
+Remember, here at Spothole Inc. we offer an industry-standard "five nines" uptime on our server, with our own unique
+twist: we don't tell you which side of the decimal point the nines start! (Translation: This is a hobby project.
+`spothole.app` runs on the same server as my blog and other stuff. It might go down without warning. By all means base
+your own project on data from the main server if you like, but if you want any control over reliability and downtime,
+please run your own copy instead.)

+## Running using Docker
+
+Spothole comes with a Docker configuration to make it easy to run it in a containerised environment. To set it up using
+Docker, the easiest way is to use a Docker Compose file. Create a new directory such as `/opt/docker/spothole` and
+create a `compose.yaml` file inside it with the following contents:
+
+```yaml
+services:
+  spothole:
+    container_name: spothole
+    build:
+      context: https://git.ianrenton.com/ian/spothole.git#main
+    restart: unless-stopped
+    ports:
+      - "8080:8080"
+    volumes:
+      - ./config.yml:/app/config.yml
+      - ./cache:/app/cache
+```
+
+You can replace `#main` with any other branch or tag reference, for example `#1.5` to pin the build to tagged version
+1.5.
+
+Save the file. You will still need to create a copy of `config-example.yml` and name it `config.yml`, though with the
+Docker setup nothing has actually been downloaded yet, so you will have to copy the example from the repository some
+other way, e.g. [from the repo in a web browser](https://git.ianrenton.com/ian/spothole/src/branch/main/config-example.yml).
+
+With that in place, run `docker compose up` and you should be good to go. To detach, press `d` or run the command with
+the `-d` flag.
+
+### nginx Reverse Proxy with Docker
+
+In a containerised setup, it's typical to run an nginx reverse proxy in one container, alongside certbot for renewal
+of HTTPS certificates, and then applications like Spothole in a separate container. In this case, there are a couple of
+variations of the docker compose file above, and the nginx reverse proxy configuration covered [here](./nginx.md), that
+you will want to make.
+
+1. A port mapping is no longer required in the docker compose file; nginx will access into the docker container directly
+   on e.g. `http://spothole:8080`
+2. Spothole and nginx will need to be on the same docker network.
+
+So your `compose.yaml` might look like this:
+
+```yaml
+services:
+  spothole:
+    container_name: spothole
+    build:
+      context: https://git.ianrenton.com/ian/spothole.git#main
+    restart: unless-stopped
+    networks:
+      - docker-network
+    volumes:
+      - ./config.yml:/app/config.yml
+      - ./cache:/app/cache
+
+networks:
+  docker-network:
+    external: true
+```
+
+In your nginx site configuration, you'll want to refer to the Spothole container directly, and drop the block that
+allows nginx to access static files directly, as these will be inaccessible in another container. So you may end up
+with something like:
+
+```nginx

+
+If desired, you could even change the port on which Spothole runs from 8080 to a plain 80, in which case your
+`proxy_pass` statements could drop the `:8080` suffix. Since Spothole is in a container, it can serve HTTP on port 80
+if desired, because it doesn't conflict with the host system.

+## Embedding Spothole in another website
+
+You can embed Spothole's web interface in another website, e.g. for use as part of a ham radio custom dashboard.
+
+URL parameters can be used to trigger an "embedded" mode which hides the headers, footers and settings. In this mode,
+you provide configuration for the various filter and display options via additional URL parameters. Any settings that
+the user has set for Spothole are ignored. This is so that the embedding site can select, for example, their choice of
+dark mode or SIG filters, which will not impact how Spothole appears when the user accesses it directly. Effectively, it
+becomes separate to their normal Spothole settings.
+
+Setting `embedded` to true is important for the rest of the settings to be applied; otherwise, the user's defaults will
+be used in preference to the URL params.
+
+These are supplied with the URL to the page you want to embed, for example for an embedded version of the band map in
+dark mode, use `https://spothole.app/bands?embedded=true&dark-mode=true`. For an embedded version of the main spots/home
+page in the system light/dark mode, use `https://spothole.app/?embedded=true`. For dark mode showing 70cm TOTA spots
+only, use `https://spothole.app/?embedded=true&dark-mode=true&sig=TOTA&band=70cm`. Providing no URL params causes the
+page to be loaded in the normal way it would when accessed directly in the user's browser.
+
+The supported parameters are as follows. Generally these match the equivalent parameters in the real Spothole API, where
+a mapping exists.
+
+| Name             | Allowed Values          | Default | Example                 | Description                                                                                                                                                           |

+## Modifying the source code
+
+Spothole is Public Domain licenced, so you can grab the source code and start modifying it for your own needs.
+Contributions of code back to the main repository are encouraged, but completely optional.
+
+### Code structure
+
+To navigate your way around the source code, this list may help.
+
+*Python back-end code*
+
+* `/core` - Core classes and scripts
+* `/data` - Data storage classes
+* `/spotproviders` - Classes providing spots by accessing the APIs of other services
+* `/alertproviders` - Classes providing alerts by accessing the APIs of other services
+* `/solarconditionsproviders` - Classes providing solar and propagation by accessing the APIs of other services
+* `/server` - Classes for running Spothole's own web server
+
+*Templates*
+
+* `/templates` - Templates used for constructing Spothole's user-targeted HTML pages
+
+*HTML/JS/CSS front-end code*
+
+* `/static` - Root for static files served by the web server. These are all served from a path starting `/static/`.
+* `/static/apidocs` - Contains the OpenAPI spec (`openapi.yml`)
+* `/static/css` - CSS files used by the web front-end
+* `/static/img` - image files used by the web front-end
+* `/static/js` - JavaScript used by the web front-end
+* `/static/vendor` - Third-party libraries (CSS, JS, fonts and images)
+
+*Miscellaneous*
+
+* `/` - Main script (`spothole.py`), pip `requirements.txt`, config, README, etc.
+* `/docs` - Documentation
+* `/images` - Image sources
+* `/datafiles` - Local data sources (differentiated from the majority of data files which are loaded from URLs and
+  cached in `/cache`)
+* `/cache` - Directory where static-ish data downloaded from the internet is cached to avoid rapid re-requests, and
+  where spot/alert data is cached so that it survives a software restart. Created on first run.
+
+### Extending the server
+
+Spothole is designed to be easily extensible. If you want to write your own spot provider, for example, simply add a
+module to the `spotproviders` package containing your class. (Currently, in order to be loaded correctly, the module (
+file) name should be the same as the class name, but lower case.)
+
+Your class should extend "SpotProvider"; if it operates by polling an HTTP Server on a timer, it can instead extend "
+HTTPSpotProvider" where some of the work is done for you.
+
+The class will need to implement a constructor that takes in the `provider_config` and provides it to the superclass
+constructor, while also taking any other config parameters it needs.
+
+If you're extending the base `SpotProvider` class, you will need to implement `start()` and `stop()` methods that start
+and stop a separate thread which handles the provider's processing needs. The thread should call `submit()` or
+`submit_batch()` when it has one or more spots to report.
+
+If you're extending the `HTTPSpotProvider` class, you will need to provide a URI to query and an interval to the
+superclass constructor. You'll then need to implement the `http_response_to_spots()` method which is called when new
+data is retrieved. Your implementation should then call `submit()` or `submit_batch()` when it has one or more spots to
+report.
+
+When constructing spots, use the comments in the Spot class and the existing implementations as an example. All
+parameters are optional, but you will at least want to provide a `time` (which must be timezone-aware) and a `dx_call`.
+
+Finally, simply add the appropriate config to the `spot_providers` section of `config.yml`, and your provider should be
+instantiated on startup.
+
+The same approach as above is also used for alert providers.

+## nginx Reverse Proxy configuration
+
+Web servers generally serve their pages from port 80. However, it's best not to serve Spothole's web interface directly
+on port 80, as that requires root privileges on a Linux system. It also and prevents us using HTTPS to serve a secure
+site, since Spothole itself doesn't directly support acting as an HTTPS server. The normal solution to this is to use
+a "reverse proxy" setup, where a general web server handles HTTP and HTTP requests (to port 80 & 443 respectively), then
+passes on the request to the back-end application (in this case Spothole). nginx is a common choice for this general web
+server.
+
+To set up nginx as a reverse proxy that sits in front of Spothole, first ensure it's installed e.g.
+`sudo apt install nginx`, and enabled e.g. `sudo systemd enable nginx`.
+
+Create a file at `/etc/nginx/sites-available/` called `spothole`. Give it the following contents, replacing
+`spothole.app` with the domain name on which you want to run Spothole. If you changed the port on which Spothole runs,
+update that on the "proxy_pass" line, and if you installed Spothole somewhere other than `/home/spothole/spothole`,
+adjust the alias location for serving static files.
+
+(The latter section, configuring the nginx server to serve static files directly, improves efficiency because it saves
+Spothole itself from serving JS, CSS etc. files. If you can't do this for some reason, e.g. your nginx and spothole are
+on different computers, you can omit the `location /static/ {}` block.)
+
+```nginx

+        proxy_read_timeout 30s;
+        add_header Cache-Control "no-cache, must-revalidate" always;
+    }
+}
+```
+
+One further change you might want to make to the file above is the `add_header Access-Control-Allow-Origin` statements.
+These are what's used on
+my own Spothole server to make sure that other third-party web-based software can get the data from my instance, and
+applies to any endpoint underneath `/api`. If you want
+*your* Spothole instance to be set up the same way, so that others can write software in JavaScript that can access it,
+leave this intact. But if you want your Spothole instance to only be usable by scripts running on the web server you
+write,
+you can remove these lines. (Note that this doesn't stop other people writing *non-web-based* software that accesses
+your
+Spothole API&mdash;the enforcement of cross-origin headers only happens within the user's browser. If you need to lock
+your
+instance down so that no-one else can access it with *any* software, that's an aspect of nginx or firewall config that
+you will need
+to find help with elsewhere.)
+
+Now, make a symbolic link to enable the site:
+
+```bash
+cd /etc/nginx/sites-enabled
+sudo ln -sf ../sites-available/spothole
+```
+
+Test that your nginx config isn't broken using `nginx -t`. If it works, restart nginx with
+`sudo systemctl restart nginx`.
+
+If you haven't already done so, set up a DNS entry to make sure requests for your domain name end up at the server
+that's running Spothole.
+
+You should now be able to access the web interface by going to the domain from your browser.
+
+Once that's working, [install certbot](https://certbot.eff.org/instructions?ws=nginx&os=snap) onto your server. Run it
+as root, and when prompted pick your domain name from the list. After a few seconds, it should successfully provision a
+certificate and modify your nginx config files automatically. You should then be able to access the site via HTTPS.

+## Running your own copy
+
+If you want to run a copy of Spothole with different configuration settings than the main instance, you can download it
+and run it on your own local machine or server.
+
+You will require Python version 3.8 or later. If you encounter an error about `gdal-config` during the following
+process, you will also need `libgdal-dev` installed.
+
+To download and set up Spothole on a Debian server, run the following commands. Other operating systems will likely be
+similar.
+
+```bash
+git clone ssh://git@git.ianrenton.com/ian/spothole.git
+cd spothole
+python3 -m venv ./.venv
+source .venv/bin/activate
+pip install -r requirements.txt
+deactivate
+cp config-example.yml config.yml
+```
+
+Then edit `config.yml` in your text editor of choice to set up the software as you like it. Mostly, this will involve
+enabling or disabling the various providers of spot and alert data.
+
+By default, all outdoor programme providers are enabled, as is one cluster node and the NG3K DXpedition data. The RBN
+spot providers are turned off by default due to the volume of traffic from CW/RTTY/FT8 skimmers, and the APRS and Packet
+spot providers are off by default on the assumption that Spothole users want a spot with a human at the other end of it,
+but all can be easily re-enabled.
+
+Other parameters you will want to update include the base URL to your instance, and whether you want to serve a full
+web-based DX cluster interface or just the API endpoints for client software to use.
+
+`config.yml` has an entry for a Clublog API key. If provided, this will allow Spothole to retrieve some more information
+about DX spots. The software will work just fine without it, but you may find a few country flags etc. are less accurate
+or missing. Clublog API keys are free, but you'll need to get your own by submitting a helpdesk ticket and explaining
+what you'll use it for. The admin team are happy with the rate of requests made by my Spothole server, so unless you
+change the source code of yours to radically increase the rate of querying Clublog, I'm sure they will be fine with your
+server too.
+
+Once you're happy with the content of `config.yml`, you can proceed to running the software.
+
+To run the software this time and any future times you want to run it directly from the command line:
+
+```bash
+source .venv/bin/activate
+python3 spothole.py
+```
+
+The software can take a few seconds to start up, mostly because it is downloading an updated file to match callsigns to
+countries. This is normal, don't panic!
+
+If you see some errors on startup, check your configuration, e.g. in case you have specified a port for the web server
+that is already in use by something else.

+If you want Spothole to run automatically on startup on a Linux distribution that uses `systemd`, follow the
+instructions here. For distros that don't use `systemd`, or Windows/OSX/etc., you can find generic instructions for your
+OS online.
+
+Create a file at `/etc/systemd/system/spothole.service`. Give it the following content, adjusting for the user you want

    ## Changelog
    
    ### 1.4
    
    * Spots can now include a "propagation_mode" field, and the `/options` call enumerates the options that can have.
+    * Added support for the Diploma de Municipios Españoles (DME) SIG
+    * Renamed some SIGs to avoid confusion between Towers, Tiles and Toilets
+    * Added `comment_names` to SIGs in the `/options`, to reflect how they might be referred to in spot comments where
+      it differs from their `name`.
+    * Added `propagation_mode` field to spots
