 # Spin up a lite-node
 
-In this guide, we’re going to use the [Lotus](../implementations/lotus.md) Filecoin implementation. We’ll show how to install a lite-node on MacOS and Ubuntu. For other Linux distributions, check out the [Lotus documentation](https://lotus.filecoin.io/lotus/install/linux/#building-from-source). To run a lite-node on Windows, install [WLS with Ubuntu](https://ubuntu.com/tutorials/install-ubuntu-on-wsl2-on-windows-10#1-overview) on your system and follow the _Ubuntu_ instructions below.
