-A utility to aggregate spots from amateur radio DX clusters and xOTA spotting sites, and provide an open JSON API as well as a website to browse the data.
+(S)pothole is a utility to aggregate "spots" from amateur radio DX clusters and xOTA spotting sites, and provide an open JSON API as well as a website to browse the data.
 
-Currently supports:
+While there are several other web-based interfaces to DX clusters, and sites that aggregate spots from various outfoor activity programmes for amateur radio, (S)pothole differentiates itself by supporting a large number of data sources, and by being "API first" rather than just providing a web front-end. This allows other software to be built on top of it.
-* DX Clusters
+
-* POTA
+The API is deliberately well-defined with an OpenAPI specification and auto-generated API documentation. The API delivers spots in a consistent format regardless of the data source, freeing developers from needing to know how each individual data source presents its data.
-* WWFF
+
-* SOTA
+(S)pothole itself is also open source, Public Domain licenced code that anyone can take and modify.
-* GMA
+
-* HEMA
+Supported data sources include DX Clusters, the Reverse Beacon Network (RBN), the APRS Internet Service (APRS-IS), POTA, SOTA, WWFF, GMA, WWBOTA, HEMA, and Parks 'n' Peaks.
