TLDR

Most of the time you don't need to care about this repo.

Please to see the guide repo.

It can works with Prisma 4.x.x-5.x.x. But you must make the query engine to match Prisma version.

The guide repo is already resolve this question.

It will check Prisma Version and download the correct version when build the docker image.

Please don't use the Migration Engine in this repo.

Best practics ref the guide repo.
