1.0.28 release

虽然 Ventoy 显示了 Unofficial 的标注信息，但是用户并不会关心，仍然会认为是 Ventoy 的问题。

Ventoy 从一开始就是一个整体的设计，并没有考虑过集成在其他bootloader或分区环境中。
Ventoy 的验证和后续新功能开发也都不会考虑这种非标准的使用方式。

因此，我决定禁止 Ventoy 在非标准环境下的使用，并且不再接受放开检查的请求。

当然，这个只是Ventoy的默认行为。Ventoy仍然是100%开源的，如果你希望把Ventoy应用在自己的环境中，你可以fork一个分支，然后修改源代码实现。

 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.

+Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files. <br/>
 With ventoy, you don't need to format the disk over and over, you just need to copy the image files to the USB drive and boot it.   
 You can copy many iso files at a time and ventoy will give you a boot menu to select them. <br/> 
 Both Legacy BIOS and UEFI are supported in the same way.<br/>
 Both MBR and GPT partition style are supported in the same way.<br/>
-Most type of OS supported(Windows/WinPE/Linux/Unix/Vmware/Xen...), 550+ ISO files are tested.  <br/>
+Most type of OS supported(Windows/WinPE/Linux/Unix/Vmware/Xen...) <br/>
-A "Ventoy Compatible" concept is introduced by ventoy, which can help to support any ISO file.
+560+ ISO files are tested. 90%+ distros in distrowatch.com supported. <br/>
 </h4>
 
 # Features
 * 100% open source
 * Simple to use
 * Fast (limited only by the speed of copying iso file)
-* Directly boot from iso/wim/img file, no extraction needed
+* Can be installed in USB/Local Disk/SSD/NVMe/SD Card
-* Legacy + UEFI supported in the same way
+* Directly boot from ISO/WIM/IMG/VHD(x)/EFI files, no extraction needed
-* UEFI Secure Boot supported (since 1.0.07+)
+* No need to be continuous in disk for ISO/IMG files
-* Persistence supported (since 1.0.11+)
 * MBR and GPT partition style supported (1.0.15+)
-* WIM files boot supported (Legacy + UEFI) (1.0.12+)
+* Legacy + UEFI supported in the same way
-* IMG files boot supported (Legacy + UEFI) (1.0.19+)
+* UEFI Secure Boot supported (1.0.07+)
-* Auto installation supported (1.0.09+)
+* Persistence supported (1.0.11+)
-* File injection supported (1.0.16+)
+* Windows/Linux auto installation supported (1.0.09+)
 * ISO files larger than 4GB supported
 * Native boot menu style for Legacy & UEFI
-* Most type of OS supported(Windows/WinPE/Linux/Unix/Vmware/Xen...), 550+ iso files tested
+* Most type of OS supported, 560+ iso files tested
+* Linux vDisk boot supported
 * Not only boot but also complete installation process
 * ISO files can be listed in List mode/TreeView mode
 * "Ventoy Compatible" concept
 * Plugin Framework
-* Menu Alias/Menu Style/Customized Menu supported
+* Injection files to runtime enviroment
+* Boot configuration file dynamically replacement
+* Highly customizable theme and menu
 * USB drive write-protected support
 * USB normal use unaffected
 * Data nondestructive during version upgrade
