-A CGI program written in C to display data related to Race CTS leaderboards of Xonotic servers.
+A common gateway inferface (CGI) program written in C to display data related to Race CTS leaderboards of Xonotic servers. It may also serve as a static page generator.
 
 ## Requirements
-* SQLite3
+    sqlite-devel python3 python-sqlite
+
+The first is only needed for compilation of the C program. The latter two are only for the auxiliary script `allmaps.py`.
+
+## Compiling
+`make` makes a cgi program.
+
+`make staticgen` makes a static page generator.
+
+## CGI Query Strings
+The program queries the database `db/cts.db` (`./src/dbquery.c`, function `static bool executequery`)

+## Static Page Generation
+The files `allmaps.py`, `output/leaderboard.css`, `template-generic.html`, `template_map-generic.html` are for static page generation. Before executing `allmaps.py`, copy and modify the templates.
+
+    cp ./template-generic.html ./template.html
+    cp ./template_map-generic.html ./template_map.html
+
+`allmaps.py` outputs an html file for all distinct maps in the database. The leaderboards for each map (equivalent to `?map=[map name]`) are in `output/maps/`.
