+### Failed to find where HEAD diverged from master
+
+You may sometimes see the following error when trying to generate changeset on your feature branch.
+
+```
+❯ pnpm changeset
+🦋  error Error: Failed to find where HEAD diverged from master. Does master exist?
+```
+
+**How to fix:**
+
+1. First you need to checkout to master branch.
+`git checkout master`
+
+2. Then get the latest changes from upstream.
+`git pull upstream master`
+
+3. Rebase the feature branch on master branch, and try generating changesets again.
+`git checkout <your_feature_branch>`
+`git rebase master`
