Hugo is a fast static site generator. Here are a few things that make it pleasant to use.
You write content in Markdown and keep structure in templates. The hugo server live reload is quick, and building a full site takes a second or two even for hundreds of pages. That makes it a good fit for blogs, docs, and personal sites.
Config lives in hugo.toml or config.toml. You define menus, taxonomies like tags, and custom params there. Content goes under content/ with front matter at the top of each file.
Sections (e.g. content/blog/) get their own list and single layouts when you add layouts/section/blog.html and layouts/blog/single.html. Use partials for the header and footer so you don’t repeat yourself.
If you’re hosting on GitHub Pages, a small workflow can build with Hugo and push the public/ output to the gh-pages branch. No need to commit generated files.
