# Recommended Hardware & Software

**Setup**

* We recommend using Linux or MacOS
* A wallet with the WAN you wish to stake + a small amount of WAN for service fees.
* You may use a cloud server such as AWS or run on bare metal. See our AWS getting started guide for more information.
* If using AWS, we recommend AWS m4.xlarge with the following configuration
  * CPU: 4
  * RAM:16G
  * Disk 600G

*For manual setup you also need:*

* [<mark style="color:blue;">Docker</mark>](https://www.docker.com/)
* Install Golang from <https://golang.org/> and set GO environment variables `$GOPATH` and `$GOROOT` if you want to build from source code.
