Dino is an open source project, so your help is very welcome! I will be very happy to include patches from you. But hacking into code is not the only one way to help. Also you can translate Dino to your language. Or just share it with your friends.
The easiest way you can get Dino source is to clone it from github. You can do it by running this command
$ git clone git://github.com/Dino-project/dfm.git
and then you can start coding. You can send me your patches by e-mail or at github.
