I added a troubleshooting guild to my Spacemacs book, to highlight some simple things you can do if you are having issues with Spacemacs. I also linked to the very useful Spacemacs debugging guide, to help you get more information when reporting issues. https://practicalli.github.io/spacemacs/install-spacemacs/troubleshooting.html

Is there a way to pretty-print the value of a variable in comments, sort of like REPL evaluating, in spacemacs?
