-### Adding a new repository to bors
-
-There are multiple steps needed to add a repository to our Bors instance:
-
-1. The [@bors] GitHub account needs to be granted write access to the
-   repository.
-
-2. Each CI provider needs to have a single GitHub Check Run to gate on. This is
-   not provided by default on GitHub Actions, but it can be simulated with
-   these two jobs, which will generate a `bors build finished` check:
-
-   ```yaml
-   end-success:
-     name: bors build finished
-     if: success()
-     runs-on: ubuntu-latest
-     needs: [ALL, OTHER, JOBS]
-     steps:
-       - name: Mark the job as successful
-         run: exit 0
-
-   end-failure:
-     name: bors build finished
-     if: "!success()"
-     runs-on: ubuntu-latest
-     needs: [ALL, OTHER, JOBS]
-     steps:
-       - name: Mark the job as a failure
-         run: exit 1
-   ```
-
-   Make sure to replace `[ALL, OTHER, JOBS]` with a list of all the jobs you
-   want to gate on.
-
-   These jobs need to run on specific branches (`auto` and `try`) so it's necessary
-   to add those branches to the list of branches tested by the CI provider. For GitHub
-   Actions that looks like this:
-
-   ```yaml
-   on:
-      push:
-          branches: [ 
-            auto,   # Added for bors
-            try     # Added for bors
-         ]
-   ```
-
-3. Add the repository name to the bors permissions array in the [team
-   repository][team-permissions.rs], and grant the `bors.REPOSITORY.review`
-   permission to the right teams or people. You can see an example of adding
-   bors permissions to a team [here][bors-permission].
-
-4. Add the repository to the `repositories` map in [the Terraform configuration
-   file][tf-repos]. This will create a webhook and inject its secret key in the
-   bors execution environment.
-
-5. Add the repository to the [Bors configuration][bors-config], taking
-   inspiration from other repositories. Note that the environment variables used
-   in that config will be set automatically as long as you completed step 3 above.
-
-6. Give it a test by commenting `@bors ping` in any PR. If you get a response back,
-   you can then try to approve the PR with `@bors r+`.
