# Installation ### Direct Download / CDN [https://unpkg.com/vuex](https://unpkg.com/vuex) [Unpkg.com](https://unpkg.com) provides NPM-based CDN links. The above link will always point to the latest release on NPM. You can also use a specific version/tag via URLs like `https://unpkg.com/vuex@2.0.0`. Include `vuex` after Vue and it will install itself automatically: ``` html ``` ### NPM ``` bash npm install vuex --save ``` ### Yarn ``` bash yarn add vuex ``` When used with a module system, you must explicitly install Vuex via `Vue.use()`: ``` js import Vue from 'vue' import Vuex from 'vuex' Vue.use(Vuex) ``` You don't need to do this when using global script tags. ### Dev Build You will have to clone directly from GitHub and build `vuex` yourself if you want to use the latest dev build. ``` bash git clone https://github.com/vuejs/vuex.git node_modules/vuex cd node_modules/vuex npm install npm run build ```
