 SYNOPSIS
 --------
 Cgitrc contains all runtime settings for cgit, including the list of git
 repositories, formatted as a line-separated list of NAME=VALUE pairs. Blank
 lines, and lines starting with '#', are ignored.
 
 
+LOCATION
+--------
+The default location of cgitrc, defined at compile time, is /etc/cgitrc. At
+runtime, cgit will consult the environment variable CGIT_CONFIG and, if
+defined, use its value instead.
+
+
 GLOBAL SETTINGS
 ---------------
 about-filter::
         Specifies a command which will be invoked to format the content of
         about pages (both top-level and for each repository). The command will
         get the content of the about-file on its STDIN, and the STDOUT from the
         command will be included verbatim on the about page. Default value:
         none.
