Thank you, mod @oups
I admit it is wrong, can not determine which PNG they can use, because I do not include the type into the folder.
brother, moderator @oups, I've tried to do what you want, please check.
I have added the PNG logomart and logotype files, which they can use on their website.
if necessary i will fix it again, hopefully you taught me
thank you, success is always for you.
