 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.

 `config.yml` has some entries for QRZ.com username & password, and Clublog API keys. If provided, these allow Spothole to retrieve more information about DX spots, such as the country their callsign corresponds to. The software will work just fine without them, 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.

     <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>

     <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), Lagos y Lagunas On the Air (LLOTA), Towers on the Air (WWTOTA), Worked All Britain (WAB), Worked All Ireland (WAI), and Toilets on the Air (TOTA).</p>

     <p>Spothole collects no data about you, and there is no way to enter personally identifying information into the site apart from by spotting and alerting through Spothole or the various services it connects to. All spots and alerts are "timed out" and deleted from the system after a set interval, which by default is one hour for spots and one week for alerts.</p>
     <p>Settings you select from Spothole's menus are sent to the server, in order to provide the data with the requested filters. They are also stored in your browser's local storage, so that your preferences are remembered between sessions.</p>

While these enumerated options are defined in this spec anyway, providing them in an API call allows us to define extra parameters, like the colours associated with bands, and also allows clients to set up their filters and features without having to have internal knowledge about, for example, what bands the server knows about. The call also returns a variety of other parameters that may be of use to a web UI, including the contents of the "web-ui-options" config section, which provides guidance for web UI implementations such as the built-in one on sensible configuration options such as the number of spots/alerts to retrieve, or the maximum age of spots to retrieve.
