 > This GitHub Action is under active development 🧑‍🏭  
 > Please, use https://github.com/grafana/k6-action instead
 
 This action allows you to easily execute k6 tests as part of your GitHub Actions workflow. 
 
-It is a wrapper over `k6 run`, with support for globs, parallel execution, and fail-fast.
+It is a wrapper over `k6 run`, with support for globs, parallel execution, fail-fast, and many other features.
 
 > This action won't setup/install k6. That functionality is provided by [grafana/setup-k6-action](https://github.com/grafana/setup-k6-action)
 
+## Inputs
+
+The following inputs can be used as `step.with` key:
+
+| Name | Type | Required | Description 
+| --- | --- | --- | --- |
+| `path` | string | `true` | Glob pattern to select one or multiple test scripts to run. <br/> e.g. `./tests/api*.js` <br/> One can also supply multiple patterns by separating them with new line.<br/><code>path: \|<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;./tests/api*.js<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;./tests/app*.js</code>
+| `cloud-run-locally` | boolean | `false` | If `true`, the tests are executed locally and the results are uploaded to Grafana Cloud k6
+| `parallel` | boolean | `false` | If `true` and multiple tests are executed, all them run in parallel. 
+| `fail-fast` | boolean | `false` | If `true`, the whole pipeline fails as soon as the first test fails 
+| `flags` | string | `false` | Additional flags to be passed on to the `k6 run` command.<br/>e.g. `--vus 10 --duration 20s`
+| `cloud-comment-on-pr` | boolean | `false` | If `true`, the workflow comments a link to the cloud test run on the pull request (if present)
+| `only-verify-scripts` | boolean | `false` | If `true`, only check if the test scripts are valid and skip the test execution'
+
