 ### Example Config
 
-#### Example - On Pull Request
-
-This is a small example of what your `action.yml` could look like (on pull request mode):
-
 ```yaml
-name: Prettier for JS Code
+name: Continuous Integration
-
-on: [pull_request]
-
-jobs:
-  cleanup_tasks:
-    runs-on: ubuntu-latest
-
-    steps:
-    - name: Cloning the repository
-      uses: actions/checkout@v1
-      with:
-        fetch-depth: 1
-    - name: Prettify the JS Code
-      uses: creyD/prettier_action@v2.1
-      with:
-        prettier_options: '--no-semi --write *.js'
-        branch: ${{ github.head_ref }}
-      env:
-        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
-```
-
-#### Example - On Push
-
-```yaml
-name: Prettier for JS Code
 
+# This action works with pull requests and pushes
 on:
+  pull_request:
   push:
-    branches: [master]
+    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@v2.1
+
+    - name: Prettify code
+      uses: creyD/prettier_action@v2.2
       with:
-        prettier_options: '--no-semi --write *.js'
+        # Push back to the same branch that was checked out
-        branch: master
+        branch: ${{ github.head_ref }}
-      env:
-        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
 ```
