+## Updating Steps
+
+Updating is extremely easy however it's important to be aware that containers managed via the Docker Compose Manager plugin do not integrate with Unraid's native dockerman ui, the label "_update ready_" will always be present on containers installed via the Docker Compose Manager.
+

+/>
+
+You should ignore the "_update ready_" on the Unraid WebUI and update when you receive the notification within the Immich WebUI.

+/>
+
+1. Go to the "**Docker**" tab and scroll to the Compose section
+2. Next to Immich click the "**Update Stack**" button and Unraid will begin to update all Immmich related containers
+   > Note: **Do not** select Compose Down first, it is unecessary.
+3. Once complete you will see a "_Connection Closed_" message, select "**Done**".

+   alt="Wait for Connection Closed and click Done"

+4. Return back to the Immich WebUI and you will see the version has been updated to the latest
