With Luke's help, I've got my Pi mining with my ASIC.   
Currently, I start it by
1) opening a terminal
2) changing to the bfgminer-3.2.1 directory
3) entering sudo ./bfgminer

I'd like it to start mining automatically when powered up.
I found this post
https://bitcointalk.org/index.php?topic=168174.msg2689279#msg2689279
but I don't think everything I need is there.

Could someone please tell me what to do, and keep in mind that Linux is a foreign language to me.
Thanks
