All languages can have a learning curve and having a reference sheet can make understanding a language like Jekyll that much easier.
CloudCannon has an easy cheat sheet you can reference for everything related to Jekyll.
It's generally difficult to learn every nuance of a programming language, but sometimes these small things can make the difference you need in a project. With a little bit of frontloaded study, you can turn hours of work in to minutes: every little trick adds up.
We highly encourage you to review the Jekyll documentation or keep the Jekyll cheat sheet handy so you can easily reference these things instead of keeping them all in your head.
