maryo is a proxy program intended to be as easy as possible to use, the user interface comes first, then the features. if i were to focus more on the features, i could end up with a program that works, but i'd then have a bunch of people asking me how to use it.
go to the releases, and download the correct binary for your system. just double-click it and follow the instructions (it's that easy!)
$ go get github.com/ReverseTeam/maryo
