 Without any configuration, the page is pretty minimal, and the user has no way to navigate around the site. To customize your site, let's first create a `.vuepress` directory inside your docs directory. This is where all VuePress-specific files will be placed in. Your project structure is probably like this:
 
 ```
-cwd
-├─── docs
-│   ├── README.md
-│   └── .vuepress
-│       └── config.js
-└── package.json
