# Installation

Let's start with the installation.

## Requirements

Please make sure your computer/server meets the following requirements:
 - [Node.js](https://nodejs.org) >= 8: Node.js is a server platform which runs JavaScript. Installation guide [here](https://nodejs.org/en/download/).
 - [MongoDB](https://www.mongodb.com/): MongoDB is a powerful document store. Installation guide [here](https://www.mongodb.com/download-center?j#community).

## Setup

Time to install Strapi!

```bash
npm install strapi@alpha -g
```

Note: if you encounter npm permissions issues, [change the permissions to npms default directory](https://docs.npmjs.com/getting-started/fixing-npm-permissions#option-1-change-the-permission-to-npms-default-directory).

It takes about 20 seconds with a good Internet connection. You can take a coffee ☕️ if you have a slow one.

Having troubles during the installation? Check if someone already had the same issue https://github.com/strapi/strapi/issues. If not, you can [post one](https://github.com/strapi/strapi/issues/new), or ask for help https://strapi.io/support.

## Check installation

Once completed, please check that the installation went well, by running:

```bash
strapi -v
```

That should print `3.0.0-alpha.x`.
