+## Continue
+
+[Continue](https://www.continue.dev/) is an open-source AI coding assistant for VS Code and JetBrains. It supports MCP servers natively via `config.yaml` (preferred) or the legacy `config.json`.
+
+### Option A — Global config · `config.yaml` (recommended)
+
+Add to `~/.continue/config.yaml` on macOS/Linux, or `%USERPROFILE%\.continue\config.yaml` on Windows:
+
+```yaml
+mcpServers:
+  - name: react-debugger
+    command: npx
+    args:
+      - -y
+      - "@nhonh/react-debugger@latest"
+      - mcp
+```
+
+### Option B — Workspace-scoped config
+
+Create `.continue/mcpServers/react-debugger.yaml` at the root of your project:
+
+```yaml
+name: react-debugger
+version: 1.0.0
+schema: v1
+mcpServers:
+  - name: react-debugger
+    command: npx
+    args:
+      - -y
+      - "@nhonh/react-debugger@latest"
+      - mcp
+```
+
+### Option C — Legacy `config.json`
+
+If you haven't migrated to YAML yet, add to `~/.continue/config.json`:
+
+```json
+{
+  "mcpServers": [
+    {
+      "name": "react-debugger",
+      "command": "npx",
+      "args": ["-y", "@nhonh/react-debugger@latest", "mcp"]
+    }
+  ]
+}
+```
+
+### Verify the tools loaded
+
+1. Open VS Code with the Continue extension installed.
+2. Switch Continue to **Agent** mode (MCP tools only work in Agent mode, not Chat mode).
+3. In the Continue chat panel, type:
