Install the Studio plugin

Download RippleStudioPlugin.lua from the Studio page.

In Roblox Studio:

1. Plugins → Plugins Folder

2. Drop the file in, or paste it into a Script and save as a local plugin

3. Game Settings → Security → enable HttpService

4. Set the Ripple URL to this site's public origin

5. Open a project here, click Connect Studio, enter the six-character code

The plugin talks only to this origin. It cannot invent a project id and pull someone else's tree.
