+# Theme Config: Homepage
+
+VitePress provides a homepage layout. To use it, specify `home: true` plus some other metadata in your root `index.md`'s [YAML frontmatter](../guide/frontmatter). This is an example of how it works:
+
+```yaml
+---
+home: true
+heroImage: /logo.png
+heroAlt: Logo image
+heroText: Hero Title
+tagline: Hero subtitle
+actionText: Get Started
+actionLink: /guide/
+features:
+- title: Simplicity First
+  details: Minimal setup with markdown-centered project structure helps you focus on writing.
+- title: Vue-Powered
+  details: Enjoy the dev experience of Vue + webpack, use Vue components in markdown, and develop custom themes with Vue.
+- title: Performant
+  details: VitePress generates pre-rendered static HTML for each page, and runs as an SPA once a page is loaded.
