# Setup Helm
#### Install a specific version of helm binary on the runner.
Acceptable values are latest or any semantic version string like 1.15.0. Use this action in workflow to define which version of helm will be used.
```yaml
- uses: azure/setup-helm@v1
with:
version: '<version>' # default is latest stable
id: install
```
Refer to the action metadata file for details about all the inputs https://github.com/Azure/setup-helm/blob/master/action.yml
