+
+### How do I use it?
+
+The most barebones configuration would be:
+
+```yaml
+- name: Install Arturo
+  uses: arturo-lang/arturo-action@main
+  with: 
+      token: ${{ secrets.GITHUB_TOKEN }}
+```
+
+Based on the runner, the action will compile and setup the appropriate, native *full* version of Arturo:
+
+| runner | binary |
+|--------|--------|
+| ubuntu-latest | amd64 / Linux |
+| macos-12 | amd64 / macOS |
+| macos-latest | arm64 (M1) / macOS |
+| windows-latest | amd64 / Windows |
+
+#### More options
+
+| option | description |
+|--------|-------------|
+| mode   | this can be either `full` or `mini` for now (default: `full`) |
+| arch   | the target architecture (default: `native`) - the main use is to compile for `arm64` on Linux |
