Publishing a sheet for a newer system

I've made a custom sheet for a system which doesn't currently have one (Gestalt by Little Red Goblin Games). It's based on the Kitchen Sink example sheet currently in the repository (though it should largely be unrecognizable at this point). I want to allow them to test it in actual games, but they only have the Plus subscription level. Since the system doesn't have any sheet yet, I figured I could try to "publish" it to be listed for use by anyone, but I don't know how to do that (and Git intimidates me, tbh). Would it be appropriate/possible to publish this sheet for the main list, and if not, what are my options? If it would be appropriate, is there a step-by-step guide to do so?

Try following the wiki here; <a href="https://wiki.roll20.net/Building_Character_Sheets#Roll20_Character_Sheets_Repository" rel="nofollow">https://wiki.roll20.net/Building_Character_Sheets#Roll20_Character_Sheets_Repository</a> &nbsp; Once your sheet has been merged into the repository, it will show up on the list of character sheet templates available when creating a new game regardless of your subscription level. BTW: you can create a Custom game as a Pro user, invite anyone to the game and even make them a co-gm if needed. Good way to test out sheets.

Seconding Vince's suggestion about making a test game yourself for them. This is what I do for all of my clients.

I've made a test game, I figured out the sheetworkers using that. The person who actually runs games on the regular is who I want to stress-test them... they use Roll20 combined with google docs at the moment for their ongoing game. I'm hoping to let them use something easier, but I don't want them to have to re-create their whole game to do so. And it would be super useful to have feedback from their casual users on the design.
