Writing Room is an open source project, and most conversations about it happen in the open on GitHub.
Bugs and feature requests
Open an issue on GitHub. For a bug, it helps to say which version of the plugin and of Sanity Studio you are on, what you did, and what the room did instead. If the room shows an error, include its text.
Help setting it up
Start with Install and Troubleshooting, which cover the problems people meet most: a Studio with auto-updates still on, two copies of the SDK, and a type missing from the Lobby. If neither answers it, open an issue and describe your setup.
Everything else
For work with Zephyr Pixels, who make Writing Room, or anything that should not be public, such as a security problem, write through zephyrpixels.dev.
Before you write
There is no support contract and no promised reply time: Writing Room is free software, maintained alongside other work. Issues are read, and a clear report is the fastest way to a fix. More about the project is in About.
