Last week, I wrote about my experience working with the team at Cloud Four, and in particular some of their great practices around PR management. Today, I wanted to talk specifically about a habit my friend Gerardo Rodriguez got me into: reviewing your own pull request. It’s pretty simple. When you create a pull request in GitHub, click on the Files changed tab, and scroll through the diff. Anywhere you’ve done something new that’s not already explained by in-code comments, add a comment in the GUI about what you did and why.
