 ### Example Config
 
-This is a small example of what your `action.yml` could look like:
-
 ```yaml
-name: Prettier for JS Code
+name: Continuous Integration
 
-on: [pull_request]
+# This action works with pull requests and pushes
+on:
+  pull_request:
+  push:
+    branches:
+    - master
 
 jobs:
-  cleanup_tasks:
+  prettier:
     runs-on: ubuntu-latest
 
     steps:
-    - name: Cloning the repository
+    - name: Checkout
-      uses: actions/checkout@v1
+      uses: actions/checkout@v2
       with:
-        fetch-depth: 1
+        # Make sure the actual branch is checked out when running on pull requests
-    - name: Prettify the JS Code
+        ref: ${{ github.head_ref }}
-      uses: creyD/prettier_action@v1.0
+
+    - name: Prettify code
+      uses: creyD/prettier_action@v2.2
       with:
-        prettier_options: '--no-semi --write src/**/*.js'
+        # This part is also where you can pass other options, for example:
-        branch: ${{ github.head_ref }}
+        prettier_options: --write **/*.{js,md}
-      env:
-        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
 ```
 
-This simple example executes `prettier --no-semi --write src/**/*.js` after someone created a Pull Request on your repository. More documentation can be found [here](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/workflow-syntax-for-github-actions).
