+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.
