+Qubes specific VM config files
+==============================
+
+Those files are placed in /rw, which survives VM restart, so can be used to customize single VM (not all VMs based on the same template).
+
+-   `/rw/config/rc.local` - script run at VM startup. Good place to change some service settings, replace config files with its copy stored in /rw/config etc. Example usage:
+
+    ``` {.wiki}
+    # Store bluetooth keys in /rw to keep them across VM restarts
+    rm -rf /var/lib/bluetooth 
+    ln -s /rw/config/var-lib-bluetooth /var/lib/bluetooth
+    ```
+
+-   `/rw/config/qubes-ip-change-hook` - script run in NetVM after external IP change (or connection to the network)
+-   `/rw/config/qubes-firewall-user-script` - script run in ProxyVM after firewall update. Good place to write own custom firewall rules
+
+Note that scripts need to be executable (chmod +x) to be used.
