+# Customizing CryptPad
+
+In order allow a variety of features to be changed and to allow site-specific changes
+to CryptPad apps while still keeping the git repository pristine, this directory exists
+to allow a set of hooks to be run.
+
+The server is configured to load files from the `/customize/` path preferentially from
+`cryptpad/customize/`, and to fall back to `cryptpad/customize.dist/` if they are not found
+
+If you wish to customize cryptpad, please **copy**
+`/customize.dist/` to `/customize` and then edit it there, this way you will still be able
+to pull from (and make pull requests to (!) the git repository.
