Installation Instruction:

• download the shimmy repository
  https://github.com/r4inm4ker/shimmy

• put that in your maya scripts directory for example like the snapshot below

• And then in your maya scene, 

  select your root joint, 

• and in script editor, 
  specify the .psa animation path and run:
