This directory contains a `src.sketch` file from which all other assets are exported or derived.
## Requirements
You'll need [Sketch](https://www.sketchapp.com/) to make any changes to this directory.
Sketch is only available for macOS, and several processes in `generate.sh` require utilities that ship with the OS, so this process must be performed on macOS.
## Install sketchtool
If you do not have `sketchtool` installed, you'll first need to install it.
