Need instructions for how to create Firestore data source

[jhight]

I installed and enabled the plugin, but I don't see any firestore option in the data source menu. Can you please add instructions for how to set up a firestore data source?

For future viewers, the plugin adds a firebase panel menu on the side, from which you can add a firebase connection. I would still recommend adding instructions.

I've added instructions on how to create a connection in the 'Getting Started' section of the plugin page at https://plugins.jetbrains.com/plugin/23609-firebase-firestore

Might be a good idea to include an example. For example I can connect to the database using java/kotlin and the cloud webpage and gcloud command line. Just get this error from the plugin.....

Using same json file etc.
