Seconding Gitpod, I really wish every repo would take the couple of seconds (to minutes, depending on how complicated) to just create the Docker config for developing it.

I use VS Code devcontainers a lot locally, and it's the same concept. This really ought to be something we aspire to as a standard IMO.

I've submitted several Gitpod + VS Code Devcontainer setup PR's to projects to spare others the pain of having to figure it out.
