Too Long; Didn't Read
The sheer idea of the magnitude of impact you making by just contributing to an open-source project is breathtaking. Imagine software that runs on thousands and thousands of users’ machines and imagine that little feature you made last week is running on all of them. Even one line fix will be a huge benefit to the community. It is important to start early rather than waiting for a perfect moment. Pick first-contribution friendly issues. Read contribution guidelines and be sure that you comply with contribution guidelines before submitting your first Pull Request.
