 # VuePress
 
 > Minimalistic docs generator with Vue component based layout system
+
+## Why
+
+- **Writing First**: minimal setup, all you need is a markdown file.
+
+- **Vue-powered**: Use custom Vue components inside markdown, and develop custom themes using Vue single file components.
+
+- **Great Dev Experience**: enjoy the same enjoyable development experience of a Vue app. Leverage the full power of webpack (hot-reload, pre-processors), generate SEO-friendly static HTML, and works as an SPA after initial page load.
+
+- **Optimized for Docs**: many [built-in markdown extensions](./markdown.md) and default theme features for writing great documentation.
+
+- **GitHub Friendly**: source markdown files can link to each other using relative links that ends in `.md` so they are also readable on GitHub, auto-generates page edit links if a repo is provided.

-## Quickstart
-
-``` bash
-# install globally
-npm install -g vuepress
-
-# create a markdown file
-echo "# Hello VuePress!" > index.md
-
-# start writing
-vuepress dev .
-
-# build
-vuepress build .
-```
-
-## Inside an Existing Project
-
-``` bash
-# install as a dependency
-npm install -D vuepress
-
-# create a docs directory
-mkdir docs
-# create a markdown file
-echo "# Hello VuePress!" > docs/index.md
-
-# start writing
-npx vuepress dev docs
-```
-
-Or, add some scripts to `package.json`:
-
-``` json
-{
-  "scripts": {
-    "docs:dev": "vuepress dev docs",
-    "docs:build": "vuepress build docs"
-  }
-}
-```
-
-Then you can start writing with:
-
-``` bash
-npm run docs:dev
-```
-
-To generate static assets, run:
-
-``` bash
-npm run docs:build
-```
-
-By default the built files will be in `.vuepress/dist`. The files can be deployed to any static file server. See [Deployment Guide](./deploy.md) for guides on deploying to popular services.
