Yes.
I wrote this in a similar thread yesterday.
I also wrote this FAQ.
There is also this official Kicad tutorial.
My advise is to temporarily forget GIT.
Learn to create and use personal libraries with your computer first. When you have mastered this, move to GIT.
Basically, to organize personal libraries, as mentioned in all the above links, you:
1/ Create a Folder with your Operating System, NOT Kicad.
2/ Create more Folders with your Operating System, to place in your original Folder.
3/ Maybe create even more Folders to place in your Folders in your Folders in your Folder; again with your Operating System.
4/ THEN you open Kicad, go to the Symbol/Footprint Editors and use File > New Library > Global > give the new Library a name and steer to the folder (created with your OS in 2/ or 3/ ) in which you wish the library to reside, then click Save.
5/ Repeat 4/ as required. Personally, I have 25 symbol libraries. @Piotr has 26… he beats me 
6/ Use the same procedure (4/ & 5/ ) to create footprint libraries.
7/ 3D libraries are not created with Kicad. 3D libraries are created with your OS. They are another set of named folders in one of the other folders created with your OS.
Copy, Import and Create symbols or footprints or 3D images and place them in their appropriate libraries.
Your tree should end up looking something like this:
*My Kicad Libraries
> *My Schematic Libraries > Various named Libraries > Symbols
> *My Footprint Libraries > Various named Libraries > Footprints
> *My 3D Images > *Various named Libraries > Images
NOTE: everything with a * is created with your OS.
When you have all the above sorted and correct and understood, it is time to move it all to GIT.
Please ask any questions if you do not understand something in this post.
