 # Jest Github Action
 
-> Jest action adding checks to your pull requests
+Main features:
+
+- Add status checks with code annotations to your pull requests
+- Comment your pull requests with code coverage table (if tests succeeded)
 
 ## Usage
 
 You can now consume the action by referencing the v1 branch
 
 ```yaml
-uses: actions/javascript-action@v1
+uses: mattallty/jest-github-action@v1
+env:
+  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+```
+
+### Overriding the test command
+
+By default, this action will execute `npm test` to run your tests.
+You can change this behavior by providing a custom `test-command` like this:
+
+```yaml
+uses: mattallty/jest-github-action@v1
+env:
+  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+with:
+  # this is just an example, this could be any command that will trigger jest
+  test-command: "yarn test"
+```
+
+### Running tests only on changed files
+
+```yaml
+uses: mattallty/jest-github-action@v1
+env:
+  GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
 with:
-  milliseconds: 1000
+  # Runs tests related to the changes since the base branch of your pull request
+  # Default to false if not set
+  changes-only: true
 ```
 
 See the [actions tab](https://github.com/mattallty/jest-github-action/actions) for runs of this action! :rocket:
