HOW TO USE:

Glossary:  
 - "shelf": folder containing Python scripts  
 - "repository": folder containing "shelves"  

1. Install
First, you need to install this addon (from blender addon installer just pick the zip file) and initialize it (enable it).
This will create a shelfy folder in your user-home like:

"C:/Users/USERNAME/.studiosetup/blender/shelfy"
or  
"/home/USERNAME/.studiosetup/blender/shelfy)"

Also, "paths.txt" will be created in root of this folder.

2. Add your repository folders to paths.txt
Edit "paths.txt" located in root of this folder to add paths of your repositories like:  
 - studio wide repository  
 - personal shelves repository  
 - per project shelves repository  
 - per department repository

(do NOT mix this with paths.txt located at the addon installation location, that one is just used as a template)  
When you finish adding your paths, go to the next step.

3. Populate repos. with folders(shelves), and scripts
Now all you want to do is:
- create folders in your repository (folder names will be shelf names inside Blender)  
- fill those folders with scripts  

folder structure example:  

So, its allways: /repository/shelf/script.py

NAMING (optional):
- by default, buttons will be named simply by scripts filename  
- or you can add custom button labels by adding this as first line of your .py script (replace "My button" text, ofc):  
    #name:My button


4. Restart Blender
Finally, restart Blender, and Shelfy tab should appear on the side menu of 3D VIEW (shortcut "n")
Notice: if the Shelfy tab doesn't appear, it most likely means that you didn't populate your shelf-dirs with scripts. If that's not the case, check the system console for possible errors (Blender>>Window>>Toggle System Console)

Have in mind that scripts i used in these examples DO NOT come with addon. You have to populate your repository with your own scripts.
