+# CONTRIBUTING
+
+We are using [GitHub Actions](https://github.com/features/actions) as a continuous integration system.
+
+For details, take a look at the following workflow configuration files:
+
+- [`workflows/integrate.yaml`](workflows/integrate.yaml)
+
+## Coding Standards
+
+We are using [`yamllint`](https://github.com/adrienverge/yamllint) to enforce coding standards in YAML files.
+
+If you do not have `yamllint` installed yet, run
+
+```sh
+$ brew install yamllint
+```
+
+to install `yamllint`.
+
+Run
+
+```sh
+$ make coding-standards
+```
+
+to detect coding standard violations.
+
+## Extra lazy?
+
+Run
+
+```sh
+$ make
+```
+
+to detect coding standard violations!
+
+## Help
+
+:bulb: Run
+
+```sh
+$ make help
+```
+
+to display a list of available targets with corresponding descriptions.
