Creating a Docker Hub Access Token

During the initial AppPack set up, you'll be prompted for a Docker Hub username and access token. These are required to download the base images for the Heroku buildpacks used by AppPack while avoiding Docker Hub's anonymous download rate limits.

1. Create a free Personal account at https://hub.docker.com/signup
2. Click "New Access Token" at https://hub.docker.com/settings/security
3. In the pop-up, give your token a description ("apppack" is fine), select Public Repo Read-only, and click "Generate"
4. Copy the person access token (it should start with dckr_pat_)
