Mention experimental protocol discovery in introduction

Let's suppose I found a way to improve intro. So I checked out origin/section/intro into a new branch "intro" and modified it. But I am not sure I should merge with master or with another branch, so I request a pull. Github already shows whether merging without conflicts is possible. You see changes below. Is this enough information to decide to pull, and merge with master? I also didn't see a way for requesting merging with another branch.
