I created a WordPress plugin development boilerplate on Github to jumpstart WordPress plugin projects.
I focused on having a clean, local Docker environment which includes an automated setup of WordPress with a configurable admin user and password. Also, it has a proper Github workflow, which builds an installable zip to make releases easy.
It comes with an example for an admin page and shortcode, to get small plugin projects started quickly.
Hope to help some people to get started ✌️.
