 # Getting Started

+\* _If your project is using webpack 3.x, you may notice some installation issues with npm. In this case, we recommend using Yarn._
 
 ## Quick Start

+The fastest way to get your VuePress project setup is to use our [create-vuepress-site generator](https://github.com/vuepressjs/create-vuepress-site/) which will help scaffold the basic VuePress site structure for you.
 
 To use it, open up your terminal in the desired directory and run the following command:
 
 ```bash
-yarn create vuepress [directoryName]

-## Manual Setup
+## Manual Installation
 
 This section will help you build a basic VuePress documentation site from ground up. If you already have an existing project and would like to keep documentation inside the project, start from Step 3.
 
 1. Create and change into a new directory
 
-   ``` bash
+   ```bash
    mkdir vuepress-starter && cd vuepress-starter
    ```
 
 2. Initialize with your preferred package manager
 
-   ``` bash
+   ```bash
    yarn init # npm init
    ```
 
 3. Install VuePress locally
 
-   ``` bash
+   ```bash
    yarn add -D vuepress # npm install -D vuepress
    ```
 
-   ::: warning
-   We currently recommend using [Yarn](https://classic.yarnpkg.com/lang/en/) instead of npm when installing VuePress into an existing project that has webpack 3.x as a dependency, because npm fails to generate the correct dependency tree in this case.
-   :::
-
 4. Create your first document
 
-   ``` bash
+   ```bash
    mkdir docs && echo '# Hello VuePress' > docs/README.md
    ```
 
 5. Add some [scripts](https://classic.yarnpkg.com/en/docs/package-json#toc-scripts) to `package.json`
 
    This step is optional but highly recommended, the rest of the documentation will assume those scripts being added.

        "docs:dev": "vuepress dev docs",
