+## Built-in Environment Variables
+

+## Example: Manual Git Clone in a Job
+
+Sometimes you may want to **clone the repository manually** instead of using `actions/checkout` (which requires Node). You can do it with the built-in variables like this:
+
+```yaml
+name: Some job name
+
+on:
+  push:
+    branches:
+      - main
+  pull_request:
+
+jobs:
+  helm-lint:
+    runs-on: docker
+    container:
+      image: alpine:latest
+    steps:
+      - name: Clone repo
+        run: |
+          echo "Cloning repository $GITHUB_REPOSITORY..."
+          git clone "${GITHUB_SERVER_URL}/${GITHUB_REPOSITORY}.git" "$GITHUB_WORKSPACE"
+          cd "$GITHUB_WORKSPACE"
+```
+
+### ✅ Notes:
+
+* `$GITHUB_SERVER_URL` → your Gitea instance URL
+* `$GITHUB_REPOSITORY` → repository full name (`owner/repo`)
+* `$GITHUB_WORKSPACE` → clone target path inside the container
+* Works **without Node**, suitable for minimal containers like `alpine/helm`
