+You can use either of these two agents for Antigravity:
+- [Antigravity CLI](https://github.com/google-gemini/gemini-cli) version **v1.6.0** or higher
+- [Antigravity 2.0](https://antigravity.google/product/antigravity-2) version **v2.0.0** or higher.
 
-**1. Install the extension:**
+> [!TIP]
+> **Migrating from Gemini CLI?**
+> If you previously installed this extension with `gemini extensions install`, you can convert it to an Antigravity plugin instead of reinstalling from scratch:
+>
+> - **On first launch of Antigravity CLI**, accept the Migration Options prompt to automatically convert your installed Gemini CLI extensions to Antigravity plugins.
+> - **Or, from your terminal**, run:
+>
+>   ```bash
+>   agy plugin import gemini
+>   ```
+> See the [official Gemini CLI → Antigravity migration guide](https://antigravity.google/docs/gcli-migration) for details on plugins, context files (`GEMINI.md` / `AGENTS.md`), and MCP server config differences (note: Antigravity uses `mcp_config.json` and the `serverUrl` field instead of `url`).
