+# Update Helm Chart Dependencies GitHub Action
+
+This GitHub Action updates the version of a specific dependency in the `Chart` and `helmfile` yaml files for one or more directories in a remote repository, and for each creates a dedicated branch with the chart changes and opens a pull request.
+
+## Features
+
+- Accepts a dependency service name and version as inputs.
+- Finds all chart directories in a remote repository.
+- Updates the version of the specified chart in all Chart.yaml and helmfile.yaml files where it is listed as a dependency.
+- Creates new branches from a specified base branch.
+- Creates a dedicated branch for each change and opens a PR with a summary of the update details.
+- Uses only Node.js built-in modules and the official GitHub Actions toolkit.
+
+## Inputs
+
+| Name           | Description                                                      | Required | Default  |
+| -------------- | ---------------------------------------------------------------- | -------- | -------- |
+| `chart-name`   | Name of the dependency to update in Chart / helmfile yaml files. | true     |          |
+| `version`      | New version to set for the dependency.                           | true     |          |
+| `github-token` | GitHub token for authentication.                                 | true     |          |
+| `target-repo`  | Target repository to open the PRs in (format: owner/repo).       | true     |          |
+| `branch`       | Branch to base the PRs on (e.g. `master`).                       | false    | `master` |
+
+## Usage
+
+```yaml
+- name: Update Helm Chart Dependencies
+  uses: map-colonies/update-chart-dependency@v1
+  with:
+    chart-name: 'my-dependency'
+    version: '1.2.3'
+    github-token: ${{ secrets.GITHUB_TOKEN }}
+    target-repo: 'owner/repo'
+    branch: 'master'
+```
+
+## Notes
+
+- The action updates only the version of the specified dependency in each chart's `Chart` and `helmfile` yaml files.
+- The action opens a dedicated branch and PR for each updated chart.
+- If no charts require updating, no PR will be opened.
