Hello All,

I am a beginner, and I will be receiving my S9 antminers in a couple weeks and was wondering about the firmware update. First of all, what is cgminer and will I need to be using that? Second of all, when it comes to firmware updates, do I need to do them all or just the latest? I see on BITMAIN's site they have 5 total updates for the S9. Any ideas on which one(s) I will need to download for a 13.5TH S9? Thank you in advance!
