Do we introduce the three options for doing the lessons and compare them?

[rkdarst]

• github web, VSCode, command line
• I was reading through things and it wasn't obvious where the three methods were compared and we make recommendations about which one to use in different cases. (Does this exist though?)
• This should be clarified before "configuring the github command line" since that's where people have to decide if they want to do the things on that page. (maybe the top of that page could have tabs with the there options, which will tell people for each option if you need to do the page's stuff and which option from the page to do).
• We probably covered it but would be good to make it more explicit so we don't forget. (is it there somewhere though?)
• For example we would say the options, and what we recommend for the course, and what we recommend for real life.
