 `config.yml` has some entries for QRZ.com username & password, and Clublog API keys.

 ### nginx Reverse Proxy configuration
 
-It's best not to serve Spothole directly on port 80, as that requires root privileges and prevents us using HTTPS, amongst other reasons.

+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.

 ### Extending the server
 
-Spothole is designed to be easily extensible. If you want to write your own provider, simply add a module to the `providers` 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.)

(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 `Provider` 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.

     <h4 class="mt-4">What are "DX", "DE" and modes?</h4>
     <p>In amateur radio terminology, the "DX" contact is the "interesting" one that is using the frequency shown and looking for callers. They might be on a remote island or just in a local park, but either way it's interesting enough that someone has "spotted" them. The callsign listed under "DE" is the person who entered the spot of the "DX" operator. "Modes" are the type of communication they are using. For example you might see "CW" which is Morse Code, or voice "modes" like SSB or FM, or more exotic "data" modes which are used for computer-to-computer communication.</p>
     <h4 class="mt-4">What data sources are supported?</h4>
-    <p>Spothole can retrieve spots from: Telnet-based DX clusters, the Reverse Beacon Network (RBN), the APRS Internet Service (APRS-IS), POTA, SOTA, WWFF, GMA, WWBOTA, HEMA, Parks 'n' Peaks, ZLOTA, WOTA, the UK Packet Repeater Network, and any site based on the xOTA software by nischu.</p>
-    <p>Spothole can retrieve alerts from: NG3K, POTA, SOTA, WWFF, Parks 'n' Peaks, WOTA and BOTA.</p>
+    <p>Spothole can retrieve spots from: <a href="https://www.dxcluster.info/telnet/">Telnet-based DX clusters</a>, the <a href="https://www.reversebeacon.net/">Reverse Beacon Network (RBN)</a>, the <a href="https://www.aprs-is.net/">APRS Internet Service (APRS-IS)</a>, <a href="https://pota.app">POTA</a>, <a href="https://www.sota.org.uk/">SOTA</a>, <a href="https://wwff.co/">WWFF</a>, <a href="https://www.cqgma.org/">GMA</a>, <a href="https://wwbota.net/">WWBOTA</a>, <a href="http://www.hema.org.uk/">HEMA</a>, <a href="https://www.parksnpeaks.org/">Parks 'n' Peaks</a>, <a href="https://ontheair.nz">ZLOTA</a>, <a href="https://www.wota.org.uk/">WOTA</a>, the <a href="https://ukpacketradio.network/">UK Packet Repeater Network</a>, and any site based on the <a href="https://github.com/nischu/xOTA">xOTA software by nischu</a>.</p>
+    <p>Spothole can retrieve alerts from: <a href="https://www.ng3k.com/">NG3K</a>, <a href="https://pota.app">POTA</a>, <a href="https://www.sota.org.uk/">SOTA</a>, <a href="https://wwff.co/">WWFF</a>, <a href="https://www.parksnpeaks.org/">Parks 'n' Peaks</a>, <a href="https://www.wota.org.uk/">WOTA</a> and <a href="https://www.beachesontheair.com/">BOTA</a>.</p>
     <p>Note that the server owner has not necessarily enabled all these data sources. In particular it is common to disable RBN, to avoid the server being swamped with FT8 traffic, and to disable APRS-IS and UK Packet Net so that the server only displays stations where there is likely to be an operator physically present for a QSO.</p>
     <p>Between the various data sources, the following Special Interest Groups (SIGs) are supported: Parks on the Air (POTA), Summits on the Air (SOTA), Worldwide Flora & Fauna (WWFF), Global Mountain Activity (GMA), Worldwide Bunkers on the Air (WWBOTA), HuMPs Excluding Marilyns Award (HEMA), Islands on the Air (IOTA), Mills on the Air (MOTA), the Amateur Radio Lighthouse Socirty (ARLHS), International Lighthouse Lightship Weekend (ILLW), Silos on the Air (SIOTA), World Castles Award (WCA), New Zealand on the Air (ZLOTA), Keith Roget Memorial National Parks Award (KRMNPA), Wainwrights on the Air (WOTA), Beaches on the Air (BOTA), Worked All Britain (WAB), Worked All Ireland (WAI), and Toilets on the Air (TOTA).</p>
+    <p>As of the time of writing in November 2025, I think Spothole captures essentially all outdoor radio programmes that have a defined reference list, and almost certainly those that have a spotting/alerting API. If you know of one I've missed, please let me know!</p>
+    <h4 class="mt-4">Why can I filter spots by both SIG and Source? Isn't that basically the same thing?</h4>
+    <p>Mostly, but not quite. While POTA spots generally come from the POTA source and so on, there are a few exceptions:</p>
+    <ol><li>Sources like GMA and Parks 'n' Peaks provide spots for multiple different programmes (SIGs).</li>
+    <li>Cluster spots may name SIGs in their comment, in which case the source remains the Cluster, but a SIG is assigned.</li>
+    <li>Some SIGs, such as Worked all Britain (WAB), don't have their own spotting site and can <em>only</em> be identified through comments on spots retrieved from other sources.</li>
+    <li>SIGs have well-defined names, whereas the server owner may name the sources as they see fit.</li></ol>
+    <p>Spothole's web interface exists not just for the end user, but also as a reference implementation for the API, so I have chosen to demonstrate both methods of filtering.</p>
     <h4 class="mt-4">How is this better than DXheat, DXsummit, POTA's own website, etc?</h4>
     <p>It's probably not? But it's nice to have choice.</p>
     <p>I think it's got three key advantages over those sites:</p>
