+Configuration Files
+~~~~~~~~~~~~~~~~~~~
+
+Upon startup, tig first reads the system wide configuration file
+(`{sysconfdir}/tigrc` by default) and then proceeds to read the user's
+configuration file (`~/.tigrc` by default). The paths to either of these files
+can be overridden through the following environment variables:
+
+TIGRC_USER::
+       Path of the user configuration file.
+
+TIGRC_SYSTEM::
+       Path of the system wide configuration file.
