 ## Features
 
-+ Nothing, I haven't written any code yet.
+### Turn-based game / Open-world game / Proxy game
+- [x] Cross-platform support
+    > Tested on Windows and Linux myself, although should work on most major OSes where `HDiffPatch` is supported.
+- [x] Does *not* require administrator/root privileges
+    > Though if issues occur during installation/upgrading process, you can always try running the program with elevated privileges to fix them.
+- [x] Download the game update (including pre-downloads if available)
+- [x] Get the game version
+- [x] Get installed voicepacks
+- [x] Installation
+- [x] Patch the game for unsupported platforms (with telemetry checking)
+    > Not applicable for the "Open-world game", since patching is unneeded to play the game.
+- [x] Repair the game (Smarter than the official launcher!)
+- [x] Update the game
+- [x] Update voicepacks 
+- [ ] Uninstall the game (Just remove the game directory lol)
+- [x] Voicepacks installation
+#### Advanced features
+- [x] Apply the update archives
+- [x] Download the update archives
+- [x] Easy to use API
 
-### Notes
+### Other games (Dreamseeker game)
+I haven't developed for them yet, but since most of the code is shared I'll do that when I have the motivation to do so.
