-C CGI Xonotic DeFrag
------------------
-A CGI program written in C to display data related to Race CTS leaderboards of Xonotic servers.
+# xdfcgi
+
+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.
+
+## Usage: CGI Query Strings
+The program queries the database `db/cts.db` (`./src/dbquery.c`, function `static bool executequery`)
 
-## Web Server Queries
 * `(none)`
     - Query file: `queries/mranks.sql`
-    - Requests the maplist of the server and related data.
+    - Requests the map list of the server and related data.
 
 * `?map=[map name]`

     - Query file: `queries/rplayers.sql`
     - Requests a player's ranks for all maps leaderboards s/he is present on.
 
+## Usage: Static Page Generation
+The CGI program is still invoked in static generation. The files `allmaps.py`, `output/leaderboard.css`, `template.html`, `template_map.html` help produce the output. 
+
+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/`.
+
+    python allmaps.py
+
 ## Game Versions Used Under:
    * Xonotic 0.8.1
    * Xonotic 0.8.2
 
 ## Compilers
+* gcc (GCC) 10.2.1
 * MinGW, GCC 4.7.1
