The setting up page can cause merge issues

[dpells]

The Initializing section of Setting Up has init, add, and commit on one line which can be confusing, and if the GitHub repo was created with a README, LICENSE, and gitignore, then the push will fail.

• Move the setup commands to different lines for clarity
• before the push command, add:
• git branch --set-upstream-to=origin/main so we can pull
• git pull --allow-unrelated-histories so that the pull won't interfere with our local files
• Either on this slide or later, we can talk about git init [proj_name]
• This brings up the possibility of two new slides: connecting to an existing GitHub repo with code; starting completely from scratch
