One of the biggest value of shellcheck is that all of its errors are documented on their wiki, and easily searchable. If you don't understand why there is an error, the wiki page will tell you why an idiom is bad, and in some cases point you to examples of how it might fail, and you'll learn something new. I wish the wiki was packaged into the tool for offline consumption.
