+## Customisation
+
+### Run a command upon file creation
+
+If you which to run a commande upon file creation (or upload), you can add a custom script in `data/scripts/new_file.sh`, this script  **must** be executable, and **must** start with `/bin/sh` not `/bin/bash`.
+
+Then add to your `.env` :
+
+```
+FILE_CREATION_SCRIPT=/scripts/new_file.sh
+```
+
+It will be called each time a new file/directory is created with the file path as the first argument
+
+### Set default permissions
+
+It is possible to set a [umask](https://www.liquidweb.com/blog/what-is-umask-and-how-to-use-it-effectively/) on all files created but this is only compatible with filebrowser versions up to 2.27, so you must set in your `.env`
+
+```
+UMASK=007
+VERSION=v2.27.9
+```
+
+If you which that all new directories have permissions `770`  and files `660`
