summary: Fast and Flexible Static Site Generator
description: |
  Hugo is a static site generator written in Go, optimized for speed and
  designed for flexibility. With its advanced templating system and fast asset
  pipelines, Hugo renders a complete site in seconds, often less.

  Due to its flexible framework, multilingual support, and powerful taxonomy
  system, Hugo is widely used to create:

  * Corporate, government, nonprofit, education, news, event, and project sites
  * Documentation sites
  * Image portfolios
  * Landing pages
  * Business, professional, and personal blogs
  * Resumes and CVs

  Use Hugo's embedded web server during development to instantly see changes to
  content, structure, behavior, and presentation. Then deploy the site to your
  host, or push changes to your Git provider for automated builds and
  deployment.
