+### GitHub Actions
+
+You can use `bump-my-version` as part of a GHA workflow. Here is an example of a workflow that bumps the version, commits the change, and tags the commit.
+
+```yaml title="GitHub Actions Workflow"
+name: Bump version
+
+on:
+  workflow_dispatch:
+      bump-type:
+        description: 'Bump type'
+        required: true
+        default: 'patch'
+        type: choice
+        options:
+        - major
+        - minor
+        - patch
+
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+      - name: Checkout the code
+        uses: actions/checkout@v4
+
+      - name: Bump version
+        id: bump
+        uses: callowayproject/bump-my-version@master
+        env:
+          BUMPVERSION_TAG: "true"
+        with:
+          args: ${{ inputs.bump-type }}
+          github-token: ${{ secrets.GH_TOKEN }}
+
+      - name: Check
+        if: steps.bump.outputs.bumped == 'true'
+        run: |
+          echo "Version was bumped from ${{ steps.bump.outputs.previous-version }} to ${{ steps.bump.outputs.current-version }}!"
+```
+
+Inputs for the bump-my-version action are:
+1. `args` - The arguments to pass to the `bump-my-version bump [args]` command. See the CLI documentation for more information.
+2. `github-token` - The GitHub token to use for committing and tagging. This is optional.
+
+Output:
+1. `bumped` - Boolean flag for whether the version was bumped.
+2. `previous-version` - Version before bump was performed.
+3. `current-version` - Version after performing bump.
+
+If you want to ensure that workflows set up with on-push trigger will also start based on those newly pushed commits or tags, you need to provide a custom PAT (`github-token`). See [here](https://github.com/orgs/community/discussions/25702).
