Tomjp all gamer

Hello all, Listen, I'm having a lot of trouble installing this wonderful mod. I have downloaded it, extracted the Endurance files to the KSP game data folder (I use Winrar and Steam version of the game) and merged the "Ships" files with the Ships folder in the KSP directory. The problem is that I cannot get this mod to work and I have tried and tried again. The parts do not show up at all in any of the buildings e.g the Endurance module isn't in Pods. This kind of thing has happened with other 0.90 mods which I want to install. Can the person who reads this please give a DETAILED guide on EXACTLY what they did to install it properly. There is definitely something I am missing here. Thankyou so much.
