 This plugin provides a bridge between neovim and the [opencode](https://github.com/sst/opencode) AI agent, creating a chat interface while capturing editor context (current file, selections) to enhance your prompts. It maintains persistent sessions tied to your workspace, allowing for continuous conversations with the AI assistant similar to what tools like Cursor AI offer.

+### Model Sorting and Favorites
+
+The provider/model picker supports intelligent sorting based on your favorites and usage history:
+
+#### Sorting Priority
+
+When you open the model picker (`<leader>op`), models are sorted in the following order:
+
+1. **Favorite models** - shown with a ⭐ icon and sorted by the order they were favorited
+2. **Recently accessed models** - sorted by most recent usage
+3. **Other models** - sorted alphabetically
+
+#### Managing Favorites
+
+In the model picker, press **`<C-f>`** to toggle the currently selected model as a favorite. Favorite models will:
+
+- Display with a ⭐ star icon prefix
+- Always appear at the top of the list
+- Persist across Neovim sessions
+
+No configuration is needed - the plugin respects and updates the OpenCode CLI format automatically.
+
 ### UI icons (disable emojis or customize)
 
 By default, opencode.nvim uses emojis for icons in the UI. If you prefer a plain, emoji-free interface, you can switch to the `text` preset or override icons individually.
