Docsy is a pre-configured Hugo theme that provides the core features and behaviors needed to create a technical documentation site.
Use Docsy to set up your documentation website, including an optional Blog section, and then spend your time focusing on authoring technical content. Depending on how you choose to configure Docsy and whether you use a hosting service that supports continuous builds, you can even just add your Markdown or HTML content file into a folder on your source repository, and then sit back while it automatically gets added to your site - complete with updated menus.
