+name: Deploy Application
+on:
+  push:
+    branches: [main]
+
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    steps:
+    - uses: actions/checkout@v4
+
+    - name: Install Go toolchain
+      uses: actions/setup-go@v5
+      with:
+          go-version: "1.23"
+
+    - name: Deploy to the Compute platform
+      uses: fastly/compute-actions@v5
+      env:
+        FASTLY_API_TOKEN: ${{ secrets.FASTLY_API_TOKEN }}
+```
