# Browser Bridge Setup
> **⚠️ Important**: Browser commands reuse your Chrome login session. You must be logged into the target website in Chrome before running commands.
OpenCLI connects to your browser through a lightweight **Browser Bridge** Chrome Extension + micro-daemon (zero config, auto-start).
## Extension Installation
### Method 1: Download Pre-built Release (Recommended)
1. Go to the GitHub [Releases page](https://github.com/jackwener/opencli/releases) and download the latest `opencli-extension.zip`.
2. Unzip the file and open `chrome://extensions`, enable **Developer mode** (top-right toggle).
3. Click **Load unpacked** and select the unzipped folder.
### Method 2: Load Unpacked Source (For Developers)
1. Open `chrome://extensions` and enable **Developer mode**.
2. Click **Load unpacked** and select the `extension/` directory from the repository.
## Verification
That's it! The daemon auto-starts when you run any browser command. No tokens, no manual configuration.
```bash
opencli doctor # Check extension + daemon connectivity
```
## How It Works
```
┌─────────────┐ WebSocket ┌──────────────┐ Chrome API ┌─────────┐
│ opencli │ ◄──────────────► │ micro-daemon │ ◄──────────────► │ Chrome │
│ (Node.js) │ localhost:19825 │ (auto-start) │ Extension │ Browser │
└─────────────┘ └──────────────┘ └─────────┘
```
The daemon manages the WebSocket connection between your CLI commands and the Chrome extension. The extension executes JavaScript in the context of web pages, with access to the logged-in session.
