+description: Useful context to use when talking about inlining Copilot Chat with VS Code.
+applyTo: '**'
+---
+
+We are working on inlining Copilot Chat into VS Code. This means we want to ship Copilot Chat as a built-in experience in VS Code, without requiring users to install a separate extension. This will allow us to reach more users and provide a more seamless experience.
+
+We need to figure out the build pipelines, the local dev setup and the UX around running VS Code with Copilot Chat as builtin.
+
+We've done the first step: simply add the vscode-copilot-chat repository as a submodule to extensions/copilot.
