 After making changes, you can test your local build in OpenCode:
 
 1. **Build the project**:
+
    ```bash
    bun run build
    ```
 
 2. **Update your OpenCode config** (`~/.config/opencode/opencode.json` or `opencode.jsonc`):
+
    ```json
    {
-     "plugin": [
+     "plugin": ["file:///absolute/path/to/oh-my-opencode/dist/index.js"]
-       "file:///absolute/path/to/oh-my-opencode/dist/index.js"
-     ]
    }
    ```
-   
+
    For example, if your project is at `/Users/yourname/projects/oh-my-opencode`:
+
    ```json
    {
-     "plugin": [
