 # Ventoy
-A new bootable USB solution.
+Ventoy is an open source tool to create bootable USB drive for ISO files.   
+With ventoy, you don't need to format the disk again and again, you just need to copy the iso file 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.  
+Both Legacy BIOS and UEFI are supported in the same way. 100+ ISO files are tested.  
+A "Ventoy Compatible" concept is introduced by ventoy, which can help to support any ISO file.  
+
+See http://www.ventoy.net for detail.
