 TerriaJS can be built and run on almost any macOS, Linux, or Windows system. The following are required to build TerriaJS:
 
 -   The Bash command shell. On macOS or Linux you almost certainly already have this. On Windows, you can easily get it by installing [Git for Windows](https://gitforwindows.org/). In the instructions below, we assume you're using a Bash command prompt.
--   [Node.js](https://nodejs.org) v14.0 or later. You can check your node version by running `node --version` on the command-line.
--   [npm](https://www.npmjs.com/) v6.0 or later. npm is usually installed automatically alongside the above. You can check your npm version by running `npm --version`.
