 By default WebDAV is disabled by default, as per [upstream docs](https://manual.seafile.com/extension/webdav/). Here's some simple instructions to modify your `seafdav.conf` to enable WebDAV if you wish to use it with Traefik.
 
+ **Option 1:** 
 - Enter Seafile Pod Shell
 - Use the CLI to enter the Seafile WebDAV (`seafdav.conf`) config file
 - Use vi commands to edit the `Enabled` to `true` and change the share name as desired (default is `/seafdav`).
 > Use `i` to insert text and and `:wq`, and `ESC key` to exit insert mode
-
 - Restart Seafile and your WebDAV share will be accessible using your domain.com/seafdav
 
+**Option 2:**
+- Add [codeserver](https://truecharts.org/guides/addons/code-server/) as addon to the deplyment.
+- Browse to `/shared/seafile/conf/seafdav.conf`
+- Change `enabled = false` to `enabled = true`
+- Restart Seafile and your WebDAV share will be accessible using your domain.com/seafdav
