 We use GitHub actions to rerender feedstocks and also run our pull request automerge service. We do not currently support builds on
 GitHub Actions.

+#### Webservices Rerendering, Version Updates, and Automerge
 
-The automerge service uses the GitHub action in this [repo](https://github.com/conda-forge/automerge-action). This action runs out of a
-Docker [container](https://hub.docker.com/repository/docker/condaforge/automerge-action) on the `prod` tag. See the

+The webservices Heroku app uses GitHub Actions to run compute-intensive background jobs, including rerendering, version updates,
+and automerge jobs. The GitHub actions runs happen on the [conda-forge-webservices repo](https://github.com/conda-forge/conda-forge-webservices).
+These runs use the [webservices-dispatch-action Docker container](https://hub.docker.com/r/condaforge/webservices-dispatch-action) for some
+operations. This container is tagged with the latest webservices version.

+PRs are automatically merged if they satisfy either of the two following sets of conditions:
 
 1. are from the `regro-cf-autotick-bot`, have `[bot-automerge]` in the title, all statuses are passing, and the feedstock allows automerge
 2. have the `automerge` label and all statuses are passing.
 
 For PRs from the `regro-cf-autotick-bot`, it can be useful to remove the `[bot-automerge]` slug from the PR title if you are making
 edits to the PR.
