-Describe the purpose of the pull request.
+There are some simple steps to get your PR merged, that are the following:
+
+- Describe your PR and why a maintainer should merge it;
+- Put the same description inside the commit body otherwise if we change github hosting you application will be based on a instable source code;
+- Write the commit header in the way that it is following these simple rules [1]
+- Make sure that your PR will pass the CI
+- Wait for an review :smile: that will not happen if one of the previous step is missing.
