Thank you againg for your time and effort... also everyone else...
So i go into that link and download the last file.. ( in pic )
then will need to SSH right?
I use ubuntu btw. Can i use putty for ssh? sorry if its noob question. If im using Linux as my main OS doesnt mean im sogood at command lines. it just means i pretend to be good 
Then After SSH. i need to do what again? im somewhat confused.
Thanks again for your time. i really appreciate this and I hope this thread can help others too who will be searching for it. in the future.
