 with your [dotfiles][].
 
 
+Setting a CHEATPATH
+----------------------
+By default, all cheatsheets are installed to `~/.cheat/`, but you can instruct
+`cheat` to look for cheatsheets in other directories by exporting a `CHEATPATH`
+environment variable:
+
+```bash
+export CHEATPATH=/path/to/my/cheats
+```
+
+You may, of course, append multiple directories to your `CHEATPATH`:
+
+```bash
+export CHEATPATH=$CHEATPATH:/path/to/more/cheats
+```
