š Keep your action's README.md up to date with the `title` and `description` from the [`action.yml`](./action.yml) file, while also automatically generating sections for the inputs, outputs, and a usage example for the action. Additionally the Action's usage example is updated to match the Action's current release.
This is both a CLI tool and GitHub Action that will read the details from a GitHub Action's [`action.yml`](./action.yml) file. Configuration can be provided through a [`.ghadocs.json`](./.ghadocs.json) file stored in the root directory of the Action's repository, via the command line when using the CLI, or through the `with:` section of this Action.
**_HOW_** š This tool uses markdown comments like this `<!-- start section --><!-- stop section -->` as delimiting tokens within your README.md file to determine where to place the generated content. You can find an example README template with all fields filled-in in the [`README.example.md`](./README.example.md) file.\*\*\*

### Stand Alone Usage - if you have a Docker Action
```sh
npx --yes github-action-readme-generator@latest
```
### Install with Yarn or NPM as a dev dependency
```sh
yarn add -D github-action-readme-generator
# or
npm i --save-dev github-action-readme-generator
```
### Add a script to your project file
You can modify the script below to include any extra variables you like or use none, and instead use a `.ghadocs.json` file.
```json
{
"scripts": {
"ghadocs": "github-action-readme-generator --readme README.md && git add README.md"
}
}
```
### Using as a Pre-commit Hook
You can automate README generation on every commit by using this tool as a pre-commit hook. This ensures your documentation stays up-to-date automatically.
1. **Install the tool locally** (if you haven't already):
```sh
npm install --save-dev github-action-readme-generator
# or
yarn add -D github-action-readme-generator
```
2. **Configure pre-commit**:
Add the following to your `.pre-commit-config.yaml` file:
```yaml
repos:
- repo: local
hooks:
- id: github-action-readme-generator
name: Generate README from action.yml
entry: npx github-action-readme-generator
language: system
files: ^(action\.yml|\.ghadocs\.json)$
pass_filenames: false
```
This configuration will automatically regenerate your README whenever `action.yml` or `.ghadocs.json` changes.
## Configuration
### Example `.ghadocs.json` with all possible values
