+This repository is the companion of an article on Arduino's blog about tools for continuous integration testing of Arduino sketches with GitHub Actions.
+
+It only serves as a basic demonstration of the [`arduino/compile-sketches` GitHub Actions action](https://github.com/arduino/compile-sketches).
