+## Development
+
+To work on the codebase you have to install all the dependencies:
+
+```sh
+# npm install
+```
+
+To run the tests:
+
+```sh
+# npm run test
+```
+
+## Enable verbose logging for a pipeline
+Additional log events with the prefix ::debug:: can be enabled by setting the secret `ACTIONS_STEP_DEBUG` to `true`.
+
+See [step-debug-logs](https://github.com/actions/toolkit/blob/master/docs/action-debugging.md#step-debug-logs) for reference.
+
+## Release
+
+To release a new version of the Action the workflow should be the following:
+
+1. `npm install` to install the dependencies.
+1. `npm run test` to see everything works as expected.
+1. `npm run build` to build the Action under the `./lib` folder.
+1. `npm run pack` to package for distribution
+1. `git add src dist` to check in the code that matters.
+1. open a PR and request a review.
