 ### QuickStart
 
+If you want to create a scaffold (with github action support) automatically you can run:
+
+```sh
+deno run --allow-read=. --allow-write=. https://deno.land/x/deno_bindgen/scaffold/scaffold.ts my_project_name
+```
+
 Annotate on top of Rust `fn`, `struct` and `enum` to make them available to Deno.
