@@ -5,6 +5,12 @@ This repo has a tool which does two things:
 1. Handle clicks from iterm
 2. Generate files which the iterm click-handler can understand
 
+# Configuration
+
+The only configuration option is `ITERM2_CMD_DIR` which sets where the files are created. This defaults to `${TMPDIR}/it2cmd` but can be set to any directory.

+**I would suggest setting `ITERM2_CMD_DIR=/tmp/it2cmd`**

 ### 4. Use the script
 
 You can now use `iterm-cmd` to generate a file which contains a command that iTerm2 can then execute. For example, run:

handle-click
