1. Download, and unzip the latest release of Prim.zip in a location of your choosing.

2. Adding the module to maya's environment file:

   1. Find the Maya.env file in your Maya installation.

      • Windows: C:\Users\<YourUsername>\Documents\maya\<MayaVersion>\Maya.env
      • MacOS: /Users/<YourUsernamer>/Library/Preferences/Autodesk/maya/2<MayaVersion>/Maya.env
      • Linux: /home/<YourUsername>/maya/<MayaVersion>/Maya.env

   2. Edit the Maya.env file with a text editor and add this line:

      • MAYA_MODULE_PATH = <Path to your prim installation folder>
      • Example: MAYA_MODULE_PATH = /Users/rafa/Documents/Dev/Prim

3. Open maya's plug-in manager in Windows > Settings/Preferences > Plug-in manager

5. Search for PrimPlugin.py and ONLY check Loaded. Do not check Auto load, this will duplicate icons in your shelf every time you open Maya.

6. Prim will be added to your Custom shelf
