 1. Compile Environment
 ==========================================
     My build environment 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.
