+All submissions MUST have the binary, binary signature, and the hash of this binary. 
+Source code must also be submitted as default. 
+This allows users to compile for themselves and verify the integrity of the package. 
+(Latest versions can be different compared to main therefor for verification, only download the latest release and verify source by building yourself.) 
+(Do not clone main unless modifying / contributing / users download from releases)
