 1. Create the container:
     - To run the container on a Github VM, follow the Codespace link above. You can connect to the Codespace using VSCode or the VSCode web editor.
     - Or follow instructions to [create a new Codespace.](https://docs.github.com/en/codespaces/developing-in-a-codespace/creating-a-codespace-for-a-repository)
     - To clone this repo and run the container locally, follow instructions to [install VSCode and Docker](https://code.visualstudio.com/docs/devcontainers/containers). Click the Dev Container link above. Don't forget to add a git remote pointing to your fork once the container is setup and you want to push changes.
 2. Wait for the container to start. This will take a few (10-15) minutes since Ruby needs to be installed, the database needs to be created, and the `bin/setup` script needs to run
