-AstroDX (Formerly named MaipadDX), is a mobile maimai simulator that builds on top of the traditional arcade experience and brings optimizations for mobile devices.
+AstroDX (Formerly named MaipadDX), is a mobile maimai simulator intended for those who don't yet have access to a cabinet, those who want to practice, and everyone interested in maimai.

+# Open-source status
+
+We initially intended for AstroDX to be fully open-source after it's uploaded to official app stores, but as the game contains paid assets, we might be only able to partially open-source AstroDX.
 
-Since AstroDX isn't published to any app stores, we wanted to make sure it's hard to be recompiled and sold unofficially (this game is free after all).
 However, If you have issues, please don't hesitate to point it out in issues and we'll try to answer them as best as we can.
 
 # Q&A
 
-Q. Which version should I download?
+## Which version should I download?
 
-> As of now, v1.1.1 is the latest stable version. You should use this if you prefer having less bugs.  
-> If you want more optimizations, a better navigation experience and reworked features (though unstable), you might want to give v2.0 a shot!
+![GitHub release (latest by date including pre-releases)](https://img.shields.io/github/v/release/2394425147/maipaddx?include_prereleases)  
+v2.0 is the latest version cycle, with full support for festival features, and a superset of simai3 syntaxes (deserialized via [SimaiSharp](https://github.com/reflektone-games/SimaiSharp)).  
+v2.0 also includes optimizations, better interfaces, and more customizations. However, it's still in its pre-beta cycle, which means features aren't fully settled, and is prone to changes.  
 
-**v2.0** is currently undergoing many changes, including a massive UI overhaul, runtime optimizations, vfx / audio system reworks, just to name a few.
-However, new features are unstable and will eventually be updated as time progresses. If you live on cutting-edge technology, this is the version for you.
+![GitHub release (latest by date)](https://img.shields.io/github/v/release/2394425147/maipaddx?label=stable)  
+If you prefer a stable build instead, v1.1.1 is the **latest stable version**. You should use this if you prefer a long-term support experience.
+
+## Wait, is there version for iOS?
+Yes (kind of)! You can join the test at [TestFlight Group A](https://testflight.apple.com/join/rACTLjPL) or [TestFlight Group B](https://testflight.apple.com/join/ocj3yptn).

+
+Due to restriction of Apple, developer must be 18 (or 19 depends on local law) to publish Applications on App Store. Currently, we borrow JiNALE TEAM's developer account for bringing TestFlight up.
+
+Each public link only can hold 10k players (count by Apple ID), so please NOT duplicate join the test if you already have AstroDX installed.
