Docker instructions are broken

[giacecco]

Colonizers looks fantastic, it would be great if you found a way to make it into a viable project and work on it regularly.

In the meantime, I've checked out the Docker instructions and they're not working, as if you had unpublished the colonizers/colonizers image. Running docker-compose up in the docker folder in fact fails saying: ERROR: Error: image colonizers/colonizers not found. I've checked on Docker hub and nothing comes up searching for colonizer.

If you're not maintaining the project that it is probably better to write that somewhere. Thanks!

Partially solved by https://github.com/Digital-Contraptions-Imaginarium/colonizers/commit/acea6fcaf3816400834217b4c70d902420e53702 . There are more problems outstanding.
