+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/crush_action@v1.0
+      with:
+        branch: ${{ github.head_ref }}
+      env:
+        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+```
+
+#### Example - On Push
+
+```yaml
+name: Optimising Pictures
+
+on:
+  push:
+    branches: [master]
+
+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
