I think I completed a pull request, my first one. But it was strange because each step involves guessing what to do; the tools don’t guide one through the entire process. My memory is not very good, but my first step (since I had no idea how to start) was to find a tutorial on the Web. It said to fork the repository and showed me where the tiny fork button was. I clicked that and the repo was imported into my Document directory and I was switched to the Windows Desktop (I wanted to do all operations in GitHub itself, but apparently that can’t be done). The WD application helped me to open the file I wanted to edit, so I edited in my change. Then I used WD to release the change (it is not called releasing, though). I have no idea what that did. I went back to the GitHub repo and clicked Pull Requests, but did not see my request. I kept looking around and discovered a tiny button next to the file itself in Code > Master to submit a pull request, so I clicked that. I saw a comparison that highlighted the change I had made. There was a button to Close Pull Request, but I had no idea what that meant, so I didn’t click it.
Is this the usual experience of a newcomer? Did I do okay? Did I miss any easier way to get this done? Is there a really good tutorial out there for doing simple things like this on Windows or on GitHub (I don’t want to use the “git” command line)?
