  By default, the GitHub REST API has an anonymous user rate limit. This can be
  hit during heavy local docs development if the server is frequently restarted.
  Creating a GitHub token and storing it as the `GITHUB_TOKEN` environment
  variable allows the user to avoid the limit.
  +Visit
  +https://github.com/settings/tokens/new?description=Chakra+website+development to
  +create a new personal access token. Once it's created, be sure to copy the token
  +string.
  +
  +You'll then run the following command in the terminal that you'll start the docs
  +from:
  +
  +```sh
  +export GITHUB_TOKEN=<PASTE YOUR TOKEN HERE>
  +```
