 # PROOF OF CONCEPT. DO NOT USE IF YOU DON'T KNOW WHAT YOU'RE DOING
 
 ### Games and regions
-This project is in the proof-of-concept stage. Currently, only **3rd glb v6.6.0** is supported. It may be possilbe to completely remove the region and version-specific data in the future. Refer to the source code in `game_payload/src` for details.

 ### Information
 The anticheat the games use is fundamentally incompatible with Wine in multiple ways. This tool launches the game without it (`injector/launcher_payload`) and imitates it's behaviour (`game_payload`).
@@ -24,6 +28,13 @@ Manual usage instructions:
 
 This tool is capable of starting the games from a different process. This may be useful for spoofing the parent process (SR is known to report it). Use `wine jadeite.exe "Z:\\wine\\path\\to\\game.exe" "Z:\\wine\\path\\to\\launcher.exe"`. `explorer.exe` is used as the default.
 
+### Configuration
+These environment variables can be used to configure the behaviour of the tool.
+
+SR-exclusive:
+- `I_WANT_A_BAN=1` - allows to launch HSR. Please only use testing accounts, as there is an extremely high risk of getting banned
+- `SRFIX_DISABLE=1` - disable shared resources fix
+
 ### Internals
 This tool consists of three parts: the main injector (`injector`), the launcher payload (`injector/launcher_payload`) and the game payload (`game_payload`).
