+
+==========================================
+1. Compile Enviroment
+==========================================
+    My build envrioment is CentOS 7.8 x86_64. So here I first explain how to create the build environment from scratch.
+    Because Ventoy is based on many open source projects, so the envrioment is important. I suggest you test it on a virtual machine first.
+
+1.1 Install CentOS 7.8
+    I use CentOS-7-x86_64-Everything-2003.iso and select Minimal install
+    
+1.2 Install Packages    
+    yum install \
+        libXpm net-tools bzip2 wget vim gcc gcc-c++ samba dos2unix glibc-devel glibc.i686 glibc-devel.i686 \
+        mpfr.i686 mpfr-devel.i686 zlib.i686 rsync autogen autoconf automake libtool gettext* bison binutils \
+        flex device-mapper-devel SDL libpciaccess libusb freetype freetype-devel gnu-free-* qemu-* virt-* \
+        libvirt* vte* NetworkManager-bluetooth brlapi fuse-devel dejavu* gnu-efi* pesign shim \
+        iscsi-initiator-utils grub2-tools zip nasm acpica-tools glibc-static zlib-static
+    
+
+
+==========================================
+2. Download Source Code
+==========================================
+2.1 Download Ventoy source code from github and decompress it. 
+    Next I assume that you have unzipped the code into the /home directory (check /home/Ventoy-master/README.md file for the directory level).
+    
+2.2 Download third-part source code
+    
+    https://www.fefe.de/dietlibc/dietlibc-0.34.tar.xz                    ===>  /home/Ventoy-master/DOC/dietlibc-0.34.tar.xz
+    https://ftp.gnu.org/gnu/grub/grub-2.04.tar.xz                        ===>  /home/Ventoy-master/GRUB2/grub-2.04.tar.xz
+    https://codeload.github.com/tianocore/edk2/zip/edk2-stable201911     ===>  /home/Ventoy-master/EDK2/edk2-edk2-stable201911.zip
+    https://codeload.github.com/relan/exfat/zip/v1.3.0                   ===>  /home/Ventoy-master/ExFAT/exfat-1.3.0.zip
+    https://codeload.github.com/libfuse/libfuse/zip/fuse-2.9.9           ===>  /home/Ventoy-master/ExFAT/libfuse-fuse-2.9.9.zip
+
+
+
+==========================================
+3. All in one script
+==========================================
+    I have made the whole build process in all_in_one.sh, you can run this script to build and pack ventoy.
+    If you want to compile a certain part separately, you can continue to refer to the later chapters of this text.
+    
+    cd /home/Ventoy-master/INSTALL
+    sh all_in_one.sh
+
+    It should be noted that, some part of Ventoy has 32bit&64bit version (like 4.9 4.10 4.11 follows)
+    all_in_one.sh only build 64bit version of them, if you want to rebuild the 32bit verison. You should create a 32bit CentOS environment and build them.
+    Fortunately these parts are few modified, you only need to build once or you can directly use the binary I have built.
+
+    Besides, after a fully compile and pack, you can only build the part you modified (for example grub2) and run ventoy_pack.sh to generate the package.
+
+
+
+==========================================
+4. Build every part of Ventoy
+==========================================
+4.1 == Build grub2 ==
+    cd /home/Ventoy-master/GRUB2
+    sh buildgrub.sh
+      
+4.2 == Build ipxe.krn ==

+4.3 == Build Ventoy2Disk.exe ==
+    Ventoy2Disk.exe is the installer in Windows platform. And it must be built in Windows with Microsoft Visual Studio (2013+).   
+    Open /home/Ventoy-master/Ventoy2Disk/Ventoy2Disk.sln with Visual Studio and build it.
+   
+4.4 == Build vtoyjump64.exe/vtoyjump32.exe ==
+    vtoyjump64.exe/vtoyjump32.exe is used to mount iso file in windows PE. You should install Microsoft Visual Studio (2013+) to build it.
+    Open /home/Ventoy-master/vtoyjump/vtoyjump.sln with Visual Studio and build it (64&32).
