Can't do anything with Interstellar mod.

[Lucky90]

Ok so I've installed the Interstellar mod Scott Manley has been using in his videos maybe like a month or two ago and to be honest I haven't really used it yet. I created a new career game and unlocked serval parts already. Still, I have no idea how to use them properly. I've watched a few videos, but the good tutorials are very scarce. I've read the Wikia page. I've tried it a bit but for some reasons I can't do anything with that mod that would be worth it. I know it's a great mod with great possibilities, but seriously the best I can do is rocket that has virtually no delta v and can gain about 1 m/s every few seconds. I can't launch anything using Interstellar parts; I can only use them on my last stage.

Anyone can either help me or give me a link to an actual good tutorial?

What I know:

1. Engines/thrusters can use different types of fuel, yet I can only manage to use LFO or Liquid and they are far from efficient. Used the way I do, the stock parts are much better.
   
2. 
   
3. I think that Interstellar thrusters require a reactor to function. I get it that reactors generate energy. How is this energy used I have no idea and why is it even useful to have them considering I get 1 m/s per second acceleration, I have no idea.
   
4. 
   
5. I know that you can attach an electric power generator to your reactor. What this electric power does is still unknown to me.
   
6. 
   
7. There are tons of different types of ressources tanks that none of the engines I have unlocked can even use.
