+### Tag push events
+
+An `on: push` workflow will also trigger when tags are pushed.
+During these events, the `actions/checkout` action will check out the `ref/tags/<tag>` git ref by default.
+This means the repository will *not* be checked out on an active branch.
+
+If you would like to run `create-pull-request` action on the tagged commit you can achieve this by creating a temporary branch as follows.
+
+```yml
+on:
+  push:
+    tags:
+      - 'v*.*.*'
+jobs:
+  example:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+
+      - name: Create a temporary tag branch
+        run: |
+          git config --global user.name 'GitHub'
+          git config --global user.email 'noreply@github.com'
+          git checkout -b temp-${GITHUB_REF:10}
+          git push --set-upstream origin temp-${GITHUB_REF:10}
+
+      - name: Create changes to pull request
+        run: <create changes here>
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v2
+        with:
+          token: ${{ secrets.GITHUB_TOKEN }}
+          base: master
+
+      - name: Delete tag branch
+        run: |
+          git push --delete origin temp-${GITHUB_REF:10}
+```
+
+This is an alternative, simpler workflow to the one above. However, this is not guaranteed to checkout the tagged commit.
+There is a chance that in between the tag being pushed and checking out the `master` branch in the workflow, another commit is made to `master`. If that possibility is not a concern, this workflow will work fine.
+
+```yml
+on:
+  push:
+    tags:
+      - 'v*.*.*'
+jobs:
+  example:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+        with:
+          ref: master

+      - name: Create changes to pull request
