How to perform a pull request on GitHub

Today, I performed my first (insignifiant) pull request on GitHub, for an open-source project (akka-http, not to name it). Just to be sure to remember the steps I followed:

• read the project contributing guidelines
• on GitHub: fork the project
• clone it
• create a topic branch
• modify required files
• add, commit, push to my forked project
• on GitHub, on the original-project page: create the pull request (I had signed the Lightbend CLA beforehand)

Reference material:

• fork a repo
• creating a pull request from a fork
