+_This action can be performed by any member of the docs team._
+
+If you use the [tagged branching strategy](/contribute/branching-strategy.md), and your release corresponds with a new branch in the repository that holds your documentation, then you also need to bump the `current` and `next` branch in the docs configuration.
+
+This step is not always required, depending on your branching strategy. For example, if you only have branches for major versions of your product (e.g. 1 and 2), and you're already publishing your docs from the `1` branch, then you don't need to bump the version branch to release version 1.2 or 1.2.3 of your documentation.
+
+1. In `assembler.yml`, specifying the new `current` and `next` branches for your repository:
+   
+    ```yml
+    your-product:
+    current: 1.1
+    next: 1.2
+    ```
+
+    Some people use `main` or `master` for their `next` branch. In this case, the `next` value doesn't need to be changed.
+
+2. Tag the PR with the `ci` label. After CI runs, confirm that the intended version branches are publishing to the link service. When links are being published as intended, they can be found at the following URL, where repo is your repo name and branch is your newly configured branch:
