 ## Intro
 
 This is a kernel module to provide `/system/xbin/su` to Android Kernel (especially to WSA).
+This is the best root solution if hidding is required. When GKI is ready, kernelsu is definitely the next generation of root.
 
-Only works on 4.17+ kernel. For older kernel, you can refer to the [origin repo](https://git.zx2c4.com/kernel-assisted-superuser).
+Only works on 4.17+ kernel (both WSA and GKI is 5.0+). For older kernel, you can refer to the [origin repo](https://git.zx2c4.com/kernel-assisted-superuser).
 
 ## How it works
 - Replace syscall `newfstatat`, `faccessat` and `execve` on `/system/xbin/su` to `/system/bin/sh`
-- When `execve` on `/system/xbin/su`, change SELinux to permissive, set all kinds of uids and gids to 0 and permit all capabilities.
-
-## Improvement
-- Instead of setting SELinux to permissive, we should set the target process to a permissive context
-- Instead of allowing all to access and execute `/system/xbin/su`, we should allow only permitive uid or gid.
