In this video, we'll learn how to create custom minor modes and hooks in Emacs Lisp! We'll also continue with our dotcrafter.el project by creating a minor mode that will cause our Org Mode configuration files to be automatically tangled when saved.

Check out the show notes here: https://systemcrafters.cc/learning-emacs-lisp/creating-minor-modes

The code for dotcrafter.el can be found here: https://github.com/daviwil/dotcrafter.el
