You will need to install these tools on your machine:
- Node.js v8.11.4
- Python 2.7
- Xcode and Xcode Command Line Tools (Xcode -> Preferences -> Downloads)

## Node.js
2018-09-03 18:28:44 +00:00
2018-09-14 20:22:58 +00:00
There are two approaches to installing Node.js, **manual** and **managed** . If you're not sure which route to go, we recommend the managed route, but do whatever makes the most sense for your development process!

### Managed

We recommend using [nvm ](https://github.com/creationix/nvm ) to manage your Node.js version. This makes it easier to know you are running the correct version of node for this project without affecting setup for other projects on your machine.

- Install nvm from https://github.com/creationix/nvm#install-script
- At the top level of this repo:
- Install the version of Node.js for GitHub Desktop with `nvm install`
- Use that version with `nvm use`
- You're good to go!

Suitable alternatives include (but aren't limited to) [n ](https://github.com/tj/n ) and [asdf-nodejs ](https://github.com/asdf-vm/asdf-nodejs ).

## Python
2018-09-10 20:22:57 +00:00
macOS comes with Python pre-installed, and it happens to be the right version, so you're probably fine! But if you use other versions of Python, here's how to get started.
