# Default Branch Update Master to Main

If you choose to switch over the default branch, for instance from master to main, a few steps must be taken to update Stacked PRs CLI to handle this change:

### 1. Ensure that local remote HEAD is updated

You can do this with `git remote set-head origin --auto`.

You can read the git man page for more details:\
<https://git-scm.com/docs/git-remote#Documentation/git-remote.txt-emset-headem>

### 2. Modify .git/av/av.db file to replace the parent

In your repository `.git` directory has a file named `.git/av/av.db`. This file is a JSON document. If you open that, you can see sections like this:<br>

<figure><img src="/files/Mg44mUf3MA50NsGuHffF" alt=""><figcaption></figcaption></figure>

This file is used by the `av` CLI to track each branch's parent. You can change `master` to `main` or whatever default branch name change you are making for all existing branches. If you are unsure, please take a backup.

\
With these two steps, av should recognize main as master, including existing branches.
