NEWBIE QUESTION - How do I download Multicas to Open Rsi

[bildav]

HELP Im STUCK- I'm a newbie - it took me ages to get my box working with the original firmware and I've been running this for over 12 months now.
I decided to take the plunge and update to Open RSi but I'm stuck.
Essentially all i want to do is find/ download MultiCas and install my c-line but I don't know how to do this.
I have tried but I'm just going round in circles
Is there a sticky anywhere or written guidance on using Open RSi (I can't find any)
If all else fails I will go back to the original firmware but I'm not even sure how would I would do this .
I cannot find a menu that could be used
Any help would be really appreciated.
many thanks

MultiCAS is only for Opensat firmware. For OpenRSI you don't need it.
Press
Menubutton - Applications - green button and choice the CAM you need.
