Hey. I struggle to find some basic documentation. Not sure if it's a SEO issue but I couldn't find documentation on how to open an existing project. A team member created a meltano project git repo, trying to use that but it doesn't seem to find the project definition.

All docs are located here: https://docs.meltano.com/. If you're launching meltano inside a folder with a meltano.yml, then it should work.
