-# 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.
+- **3rd**: glb/sea/tw/kr/jp **v7.1.0+**, cn **v7.2.0+**
+- **SR**: os/cn **v1.6.0** (potentially unsafe, but no bans were reported since v1.1.0)
+
+You can expect newer versions to work immediately after release with the same jadeite binary if the version is specified with a + above.
 
 ### Information
-The anticheat the games use is fundamentally incompatible with Wine in multiple ways. This tool launches the game without it (`inject/launcher_payload`) and imitates it's behaviour (`game_payload`).
+The anticheat the games use is fundamentally incompatible with Wine in multiple ways. This tool launches the game without it (`injector`) and imitates it's behaviour (`game_payload`).
 
-Does not work on Windows.
+**Using third-party software (such as this tool) with the games violates their Terms of Service**. Therefore, **you may receive a ban**. No bans were ever reported with 3rd, however the legacy patch for SR did cause many. **Use at your own risk and only if you understand all the possible consequences**.
+
+**This is not a cheating tool**. Using it with Windows is not possible, and Windows support is not planned or intended in any way. However, as it does not perform any on-disk file modifications, you may reuse the same game install for Windows if you have a dual-boot setup.
 
 ### Usage
-**Refer to [Third-party launchers](#third-party-launchers) (will be written later)** for convenient usage. If you don't want to (or can't) use third-party launchers, continue reading the section below.
+**Refer to [third-party launchers](#third-party-launchers)** for convenient usage. If you don't want to (or can't) use third-party launchers, continue reading the section below.
 
 **Wine 8.0+ is recommended**, as lower versions leak "The Wine project" as the device identifier. Not critical, but taking a precaution never hurt anyone. **DXVK is strongly recommended.**
 
-3rd-specific: In some cases, and if you're not using Proton GE, **a fix for Media Foundation may be required to play videos. The Game may crash without it.** You can download it from [here](https://github.com/z0z0z/mf-install). You might need to [limit the number of cores available to the game](https://github.com/z0z0z/mf-install/issues/44) if your CPU has more than 8.
+**3rd-specific**: 
+- **Wine 8.21+ or [Wine-GE-Proton](https://github.com/GloriousEggroll/wine-ge-custom) is required to play videos. The game may show a black screen or crash on lower versions.** 
+- You might need to [limit the number of cores available to the game](https://github.com/z0z0z/mf-install/issues/44) if your CPU has more than 8.
 
 Manual usage instructions:
 - Download the game you want to run
-- Download a release from this repository
+- Download the latest release from this repository
 - Extract the archive (**NOT INTO THE GAME DIRECTORY! THIS IS IMPORTANT!**)
-- Block analytics servers in your `hosts` file. You can find the list in SERVERS.txt
-- Run `wine jadeite.exe "Z:\\wine\\path\\to\\game.exe"`
+- Run `./block_analytics.sh` from the archive to block the games from accessing analytics servers (you might have to do a `chmod +x block_analytics.sh` first). This will require superuser privileges 
+- Run `wine jadeite.exe 'Z:\wine\path\to\game.exe'`
 
-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.

+
+To pass commandline arguments to the game, append them after the launcher path: `wine jadeite.exe 'Z:\wine\path\to\game.exe' 'Z:\wine\path\to\launcher.exe' -arg1 -arg2 -arg3`. To use the default launcher process, use `--`: `wine jadeite.exe 'Z:\wine\path\to\game.exe' -- -arg1 -arg2 -arg3`.
+
+### Configuration
+These environment variables can be used to configure the behaviour of the tool. Any value except empty string counts as set. `1` will be used in all examples.
+
+- `WAIT_BEFORE_RESUME=1` - show a messagebox and wait for user input before resuming the game process. Useful on my side for debugging
 
 ### Internals
-This tool consists of three parts: the main injector (`injector`), the launcher payload (`injector/launcher_payload`) and the game payload (`game_payload`).
