Where to find a complete Arduino KiCad library?

I gave up using Frietzing because of being to difficult for me to read its drawings.

Does anyone know where to find a complete KiCad Arduino library?

I am working on Arduino nano and various sensors and LCDs.

I came across this one:

And the tutorial to add libraries:

My attempts to install it according to the above failed: either unable to add a path or Kicad offering me only parts of the board - and not all the parts anyway.

Perhaps is just my lack of knowledge or inspiration.

Thank you very much for any hint/link!
