Hello and welcome,
Yes, all the information on KODI can be overwhelming. Right now you are at the only OFFICIAL Kodi forum and help site. On here you will come across a mix of fanatical users (like me) and the people that actually write the program who can be recognised by their "Team-Kodi" badges under their username. There is no better place to be for help.
What is Kodi? Basically it is a media player. It will play your videos, music, TV and photos. You can also download Official Kodi Add-ons that allow you to legally access media on-line.
It is important to remember that Kodi does not provide you any content whatsoever. It expects you to have your own music, videos etc.
As most of us know, there are unofficial piracy Add-Ons that have been created to access pirated content on the internet. This site does not support any of that and the mere mention of one of those add-ons is enough to have your question sent to the bin. (check out the garbage bin forum).
So, when you say you would like to access the YES Network... of course you mean legally with a paid subscription (if one is required) and not via a piracy add-on, right??
Anyway, a quick search shows no official app for that network.
Also, there is an incomplete list of banned add-ons here
