Improve OAuth documentation for easy configuration

- Add "Quick Setup" section showing simplest paths
- Add "Pre-configured MCP Host Setup" with examples
- Show Claude and VS Code configuration patterns
- Emphasize that port binding is straightforward and automated
- Provide ready-to-use config snippets for distribution

 - **Docker container**: Uses device flow (displays code + URL, no callback needed)
 - **Docker with port binding**: Can use PKCE flow with `--oauth-callback-port`
 
+#### Quick Setup
+
+**Option 1: Device Flow (Easiest for Docker)**
+```bash
+# 1. Create GitHub OAuth App at https://github.com/settings/developers
+# 2. Run with Docker (device flow automatic)
+docker run -i --rm -e GITHUB_OAUTH_CLIENT_ID=your_client_id ghcr.io/github/github-mcp-server
+# → Displays: Visit https://github.com/login/device and enter code: ABCD-1234
+```
+
+**Option 2: Interactive Flow (Best UX)**
+```bash
+# For native binary
+export GITHUB_OAUTH_CLIENT_ID=your_client_id
+./github-mcp-server stdio
+# → Browser opens automatically
+
+# For Docker with port binding (requires setup in OAuth app callback)
+docker run -i --rm -p 8080:8080 \
+  -e GITHUB_OAUTH_CLIENT_ID=your_client_id \
+  -e GITHUB_OAUTH_CALLBACK_PORT=8080 \
+  ghcr.io/github/github-mcp-server

+#### Pre-configured MCP Host Setup
+
+OAuth can be pre-configured for MCP hosts (similar to PAT distribution). For Docker with port binding:
+
+**Claude Desktop/Code:**
+```bash
+claude mcp add github \
+  -e GITHUB_OAUTH_CLIENT_ID=your_client_id \
+  -e GITHUB_OAUTH_CALLBACK_PORT=8080 \
+  -- docker run -i --rm -p 8080:8080 -e GITHUB_OAUTH_CLIENT_ID -e GITHUB_OAUTH_CALLBACK_PORT ghcr.io/github/github-mcp-server
+```
+
+**VS Code (settings.json):**
+```json
+{
+  "mcp": {
+    "servers": {
+      "github": {
+        "command": "docker",

+Port binding setup is straightforward and can be automated through installation instructions.
