[JOSS REVIEW] Simplify installation instructions

[finsberg]

Thanks for a great package!

I think the installation instruction could be simplified a lot which would make the library much more appealing to a greater audience.

• [x] #3

• [x] Create an ambit docker image: Instead to asking the user to first pull the dolfinx docker image, it would be better if you could build your own ambit image on top of dolfinx. That way, users could pull your image directly without the need to care about dolfinx. Also, this has another advantage that if dolfinx updates and breaks ambit you can still ship your own docker image that is based on an earlier version of dolfinx and then build new images when you have fixed all issues with the new version of dolfinx. You can see how this was can be set up here: https://github.com/finsberg/fenicsx-pulse/blob/main/.github/workflows/docker-image.yml

• [ ] Conda package: Since dolfinx is also availabel on conda it would be good to also upload ambit to conda forge. You read how to do this here

Thanks for identifying this. This has helped a lot. I'm closing the issue now since you've mentioned that it has been satisfactorily addressed.
