Unity's plugin adds a set of Unity skills to Codex, so you can ask for Unity work in plain language instead of supplying the same context each time. Install the plugin, then verify that Codex loads the skills. For a description of the skills and how to prompt them, refer to [About Unity's plugin](./about-unity-plugin.md).
