-
-==========================================
-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 environment 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-* \

-        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

-
-
-
-==========================================
-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.

+==========================================
+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 environment is important. I suggest you test it on a virtual machine firstly.
+
+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 xorriso
+    
+
+
+==========================================
+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 layout).
+    
+2.2 Download third-part source code and tool

+    better to add this line to /root/.bashrc and relogin as root
+
+
+==========================================
+3. All in one script
+==========================================
+    I have made a 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:
+    1. Only grub2/EDK2/IPXE will be recompiled in all_in_one.sh. Other part contains the binaries and are few modified, so will no be recompiled everytime.
+       You can rebuild these parts separately if you want.
+       
+    2. 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
