Describe the bug
There is a paragraph describing watchtower self-updates, but it appears under a heading for slack notifications.

To Reproduce

1. Go to https://containrrr.dev/watchtower/notifications/#slack
2. Read the first paragraph. Seems like this paragraph might belong elsewhere:

If watchtower is monitoring the same Docker daemon under which the watchtower container itself is running (i.e. if you volume-mounted /var/run/docker.sock into the watchtower container) then it has the ability to update itself. If a new version of the containrrr/watchtower image is pushed to the Docker Hub, your watchtower will pull down the new image and restart itself automatically.

Expected behavior
This paragraph might be better organized in a different section of the documentation. Maybe under Usage overview , or perhaps under its own dedicated heading.
