 # Get-Branch-Name Github Action
 
-This action outputs the current branch name and corresponding tag.
+This action outputs the current branch name and corresponding tag. Composite action: one `bash` step, no container build per run and no Node runtime to deprecate.
 
 ## Outputs
+
 ### `branch`
-The current branch name.
+
+The current branch name — `GITHUB_REF` with the `refs/heads/` prefix removed. Refs that are not branches (tags, pull requests) come through unchanged, e.g. `refs/tags/v1`.
 
 ### `tag`
-The corresponding tag name. If `master` -> `latest`, `branch-name` for the others.
+
+`master` on the master branch, `latest` when the ref is a tag, empty otherwise.
 
 ## Example usage
+
+```yaml
+- name: Get Current Branch
+  id: get-branch
+  uses: codio/get-branch-name-github-action@v2
+
+- run: echo "${{ steps.get-branch.outputs.branch }} / ${{ steps.get-branch.outputs.tag }}"
 ```
