Assuming you have git and the Xcode Developer Command Line Tools installed…

1. Clone the repository
2. Install Yarn
3. Run npm install from within the repository
4. Run yarn docs:dev to run the site locally in dev mode

Be sure to preface all code samples with ```glsl to have proper syntax highlighting. If you only use ``` it assumes the code is plaintext and disables highlighting.

Static assets, like images, should be put in /doc/.vuepress/public and linked to via a normal HTML <img /> element. Look in quickstart.md for examples.
