+### OpenCode
+
+#### Installation
+
+Add the plugin to your `opencode.json`:
+
+```json
+{
+  "plugin": ["opencode-devglobe"]
+}
+```
+
+OpenCode installs it automatically on startup via npm.
+
+#### Setup
+
+Restart OpenCode and ask:
+
+```
+setup devglobe with my key YOUR_API_KEY
+```
+
+Get your API key at [devglobe.xyz](https://devglobe.xyz) — sign in, then open your **profile settings**.
+
+#### Features
+
+| Feature | Description |
+|---------|-------------|
+| **Live heartbeat** | Hooks into `tool.execute.after` and `file.edited` events. Sends a heartbeat at most once per minute. |
+| **Language detection** | Detects the language from exact file paths provided by OpenCode tool calls. |
+| **Git integration** | Detects your repo from the git remote. |
+| **Anonymous mode** | **Enabled by default.** Hides your exact location — placed on a random city in your country (from a database of 152,000+ cities worldwide). |
+| **Repo sharing** | Ask "share my repo on devglobe" to toggle (disabled by default). |
+
+#### Commands
+
+Just ask in natural language — the plugin registers tools that the AI agent calls on your behalf:
+
+| What you say | Tool | Description |
+|--------------|------|-------------|
+| "setup devglobe with key X" | `devglobe_setup` | Configure API key and create settings |
+| "enable anonymous mode" | `devglobe_anonymous` | Toggle anonymous mode |
+| "share my repo on devglobe" | `devglobe_share_repo` | Toggle repo sharing |
+| "set my devglobe status to X" | `devglobe_status` | Set a status message on the globe |
+| "check devglobe" | `devglobe_check` | Verify installation |
