-# AG X (Antigravity fork) v2.0.3
+# AG X — Antigravity Fork
 
-AI-Powered Code Intelligence — agentic desktop application with multi-provider AI support.
+**AG X** is a fork of the Antigravity desktop application with enhanced multi-provider support. It allows you to use Google OAuth or any custom OpenAI-compatible API provider.
 
-## What's New in v2.0.3
+![AG X Icon](icon.png)
-
-### 🐛 Critical Fix: Provider Selection Flow
-- **Welcome screen now shows BEFORE the Language Server starts** — on first run, the user picks a provider before the LS launches, preventing the Google OAuth prompt from appearing for non-Google providers.
-- **Provider config syncs to `~/.codex/endpoints.json`** — the provider choice from the welcome screen and settings panel is properly synced to the endpoints config that the translation proxy reads.
-- **"Another AI Provider" flow fixed** — when user picks a custom provider, the settings panel opens and the app waits for the user to configure and save their provider before starting the Language Server.
-
-### Changes
-| File | Change |
-|---|---|
-| `main.js` | Restructured startup: welcome screen before LS start |
-| `main.js` | Added `syncProviderToEndpoints()` function |
-| `main.js` | Google Gemini handler sets active endpoint in `endpoints.json` |
-| `main.js` | Custom provider handler waits for settings save before continuing |
-| `providerSettings.js` | Save handler syncs to `endpoints.json` and emits `provider:settings-saved` |
-| `providerSettings.js` | Added close-settings IPC listener |
-| `settings.html` | Save handler shows restart notification and auto-closes |
