+## Configuration file
+
+You can use the configuration file to change the behaviour of haur. By default, the configuration file is stored in `/etc/haurrc`. However, you can also copy it to `~/.config/haurrc`. These are currently the only supported options.
+
+To disable colors (even if your terminal supports them), set `HAUR_NO_COLORS="y"`
+
+To clear cache even without specifying `-c`, set `HAUR_ALWAYS_CLEAR_CACHE="y"`
+
+If you think of another useful configuration option, tell me in a GitHub issue/pull request and/or an AUR comment.
