How to install planet packs?

[ruiluth]

I've been wondering about getting new solar systems to give me an excuse to build huge ships with tens of thousands of m/s of dV. Also I explored every planet back in 0.16 and they all feel a little too... familiar. I managed to figure out that such things exist, but I am really at a loss trying to understand how to make it happen. I'd really appreciate if anyone would be so kind as to answer a few questions I have:

1. Where do I get Kopernicus? There seem to be a few different threads and I'm not sure which is the "official" up to date one.
2. How do I install this? Is it as simple as putting folders in Gamedata like all the other mods?
3. Will I have to start a new save? I've already started over a few times due to discovering other mods, and I'd like if all my existing flights could just transfer smoothly into the new universe.

If someone can help me solve these things then I think I can figure the rest out on my own. Thanks to whoever can help.

Thank you, I'm glad it turned out to be that simple.
