 ### macOS
 
-> **NOTE**: macOS 11 or higher is required. The app is not universal. It should run on Apple Silicon under Rosetta 2, but I haven't tried it. The app is neither signed, nor notarized.
+> **NOTE**: macOS 10.11 (El Capitan) or higher is required. Runs natively on Intel-based Macs and Apple Silicon.
 
 - Use Windows installation as a base - it contains data assets needed to play. Copy `Fallout2` folder somewhere, for example `/Applications/Fallout2`.
 
+- Alternatively you can use Fallout 2 from Macplay/The Omni Group as a base - you need to extract game assets from the original bundle. Mount CD/DMG, right click `Fallout 2` -> `Show Package Contents`, navigate to `Contents/Resources`. Copy `GameData` folder somewhere, for example `/Applications/Fallout2`.
+
 - Download and copy `fallout2-ce.app` to this folder.
 
 - Run `fallout2-ce.app`.
 
-- When running for the first time, macOS will complain that the app is not signed and you'll be present two options - `Move to bin`, and `Cancel`. Click `Cancel`, open `System Preferences`, go to `Security & Privacy`. The pane at the bottom will say `fallout2-ce was blocked from use because it is not from an identified developer`. Click `Open Anyway`. Confirm once again. Alternatively you can remove quarantine attribute from terminal:
+### Android
 
-```console
-$ xattr -d com.apple.quarantine /Applications/Fallout2/fallout2-ce.app
-```
+> **NOTE**: Fallout 2 was designed with mouse in mind. There are many controls that require precise cursor positioning, which is not possible with fingers. When playing on Android you'll use fingers to move mouse cursor, not a character, or a map. Double tap to "click" left mouse button in the current cursor position, triple tap to "click" right mouse button. It might feel awkward at first, but it's super handy - you can play with just a thumb. This is not set in stone and might change in the future.
+
+- Use Windows installation as a base - it contains data assets needed to play. Copy `Fallout2` folder to your device, for example to `Downloads`. You need `master.dat`, `critter.dat`, `patch000.dat`, and `data` folder.
+
+- Download `fallout2-ce.apk` and copy it to your device. Open it with file explorer, follow instructions (install from unknown source).
+
+- When you run the game for the first time it will immediately present file picker. Select the folder from the first step. Wait until this data is copied. A loading dialog will appear, just wait for about 30 seconds. The game will start automatically.
 
 ## Contributing
 
-For now there are three major areas.
+Integrating Sfall goodies is the top priority. Quality of life updates are OK too. Please no large scale refactorings at this time as we need to reconcile changes from Reference Edition, which will make this process slow and error-prone. In any case open up an issue with your suggestion or to notify other people that something is being worked on.
 
 ### Intergrating Sfall
 
 There are literally hundreds if not thousands of fixes and features in sfall. I guess not all of them are needed in Community Edition, but for the sake of compatibility with big mods out there, let's integrate them all.
 
-### SDL
+## License
 
-Migrate DirectX stuff to SDL. This is the shortest path to native Linux version.
-
-### Prepare to 64-bit
-
-Modern macOS requires apps to be 64-bit, so even if we have SDL, the scripting part of the game will not work, because of builtin SSL interpreter. It stores pointers (both functions and variables) as 32-bit integers, so 64-bit pointers will not fit into stack. Since the stack is shared for both instructions and data, it needs some attention.
