So you want to use Ninja? It's a very clean interface!

If you still want so, you MUST have a already working Shinken installation before linking it to Ninja of course. It's you Shinken is not working, look at the installation forum

The Ninja configuration is not so hard. For this, you need to read the installation documentation available HERE.

If you follow it and you got some troubles, then you can post here, we will be glad to help you ;D
