Add new env vars to readme

Installs apprise and allows config of alerting for successful or failed renewals. Currently only supports renewals, not inital issuing. Not necessarily a problem as I'd hope you'd be watching the logs on first run.
I don't love how I create /config/.renew-list.sh. I should readdress this somehow

 ## Tags
 
-I use the [Feature Branch](https://www.atlassian.com/git/tutorials/comparing-workflows/feature-branch-workflow) workflow. The `latest` tag contains all of the latest changes that have been merged from individual feature branches. Feature branches are squashed into `master`.
-
-Pinned releases are created by creating a tag off `master` to capture the repo in a particular state. They are recommended for stability.
+|Tag    |Description|
+|-------|-----------|
+|latest |Latest image built from the main branch. Usually coincides with a tagged release.|
+|develop|Latest image built from the develop branch. Commits are made to the develop branch before being merged to main. Old versions of `develop` are removed after 14 days.|
