 ## Introduction 
 - [MBCP (MBBank CorePatch)](https://t.me/mbbpatch) are closed source before, and many people don't like it because worry about security & privacy issues. 
-- In order to support community and make MBCP open source, We spend days to rewritten whole `MBCPApp` patches in Bash and open it so you can patch it yourself on (Bare metal/VM, not WSL) Linux environment (where we used to patch `MBCP`) 
+- In order to support community and make MBCP open source, We spend days to rewritten whole `MBCPApp` patches in Bash and open it so you can patch it yourself on (Bare metal, not WSL) Linux environment (where we used to patch `MBCP`) 
+
+## Requirements
+- Actual Linux environment (not on virtualized environment like WSL) and any compatible distro (Arch Linux based recommended)
+- Little knowledge about `bash` commands 
+- `git` installed
+- `java` or `jdk-openjdk` installed
+
+## Usage
+- Go to home directory, then clone repository first
+```
+cd ~
+git clone https://gitlab.com/cuynu/mbbpatch.git
+cd ~/mbbpatch/MBCPApp
+```
+
+- Since MB Bank are now using split APK (*.apks) since `v5.3 (135)` so you have to convert it to regular APK first
+- Get MB Bank apks from [eMBee APKs](https://t.me/embeeapks) and copy it to `~/mbbpatch/MBCPApp/mbapk`
+
+- Run bash `mbcpapp.sh` script
+```
+cd ~/mbbpatch/MBCPApp
+./mbcpapp.sh
+```
+- Download necessary tools first with `Download tools` function (otherwise other function with unlikely to work!)
+- Convert apks to apk first using `Convert apks to apk` function
+- Unpack apk with `Unpack apk` function
+- Check if MBShield present on unpacked APK with `Check MBShield` function 
+(if MBShield present then you have to extract assets from Android device with `Extract assets [ROOT]`)
+- After extracted assets (if MBShield present), use `Patch App` function and select the patches you want to apply to unpacked app
+- When done, use `Repack APK` function to recompile apk (You must have Android device connected with debugging mode enabled!)
+- Output will be `MBCP_Flutter.zip` on `~/mbbpatch/MBCPApp/mbcpapp_apk/` and `mbsig.apk` will be copied to Android internal storage
+- Use [MT Manager](https://mt2.cn/), put all files inside `MBCP_Flutter.zip` to `mbsig.apk` and untick `AUTO SIGN`
+- Install it to your device (requires [MBCP Helper](https://gitlab.com/cuynu/mbcp-helper/-/releases) / [CorePatch](https://github.com/lsposed/corepatch/releases) ) due to unsigned APK
+- Profit :)
