 The Hugo **Documentation Template** empowers with everything you need to build a beautiful documentation website, including a customizable block-based homepage and blog. It's ultra-fast and easy, letting you focus on your content. It's also no-code by default, so no JavaScript knowledge is required unlike other templates!
