When I go to add my meltano project to git, what do I actually need to add and what will be recreated when I do a

meltano install

? Perhaps a

meltano clean

command would be useful?

https://meltano.com/docs/plugin-management.html#removing-a-plugin-from-your-project is the closest direct answer. For some tangents 😄 : https://gitlab.com/meltano/meltano/-/issues/2353 I think is pretty close to what you're asking for. I thought the same thing when I spun up Meltano. Figured out that removing isn't really needed based on the Meltano architecture. Running meltano install on whatever you're trying to install / upgrade does everything you need.

https://meltano.com/docs/project.html#gitignore is related too:

A newly initialized project comes with a `.gitignore` file

to ensure that environment-specific and potentially sensitive configuration stored inside the `.meltano` directory and `.env` file is not leaked accidentally.

All other files are recommended to be checked into the repository and shared between all users and environments that may use the project.
