 ## What is GitHub Copilot?
 
 GitHub Copilot is GitHub's AI coding assistant. It provides access to Copilot
 models for your GitHub account and plan. OpenClaw can use Copilot as a model

-## Two ways to use Copilot in OpenClaw
+This is the recommended and supported path for integrating Copilot with
-
+OpenClaw.
-### 1) Built-in GitHub Copilot provider (`github-copilot`)
-
-Use the native device-login flow to obtain a GitHub token, then exchange it for
-Copilot API tokens when OpenClaw runs. This is the **default** and simplest path
-because it does not require VS Code.
-
-### 2) Copilot Proxy plugin (`copilot-proxy`)
-
-Use the **Copilot Proxy** VS Code extension as a local bridge. OpenClaw talks to
-the proxy’s `/v1` endpoint and uses the model list you configure there. Choose
-this when you already run Copilot Proxy in VS Code or need to route through it.
-You must enable the plugin and keep the VS Code extension running.

 ## CLI setup
 
+Run the OpenClaw login flow to create an auth profile:

 ```bash

-## Enable
-
-Bundled plugins are disabled by default. Enable this one:
-
-```bash
-openclaw plugins enable copilot-proxy

-
-Restart the Gateway after enabling.

-## Authenticate
-
-```bash

-
-- Copilot Proxy must be running in VS Code.
-- Base URL must include `/v1`.
