Aquamin is a minimal starting point for custom WordPress theme development. It starts off with a white page with blue links that turn purple when you click them—in other words, practically nothing—allowing you to add your own code rather than wrestling with a bunch of pre-fab stuff. But, it also comes with some handy, commonly-used features and tooling so you needn't waste time building them from scratch.
Checkout the aquamin docs to get started. Happy coding!
💡 Hint: To open the docs up locally, run
npm install && npm run docswithin the theme's directory.
