+## How does this PR impact the user?
+Describe (in plain English, not technical Jargon) how this improves the user experience. If you can't tie it back to a real tangible, user goal or describe it in plain english, it's a hint that this is likely not needed and is probably and "engineering nit". 
+
+### GOOD:
+"As a user, I need to serve models faster. This PR focuses on enabling speed gains by using GPUs"
+
+### BAD:
+"This PR enables GPUs". 
+This is bad becuase the *user problem* is not clear... instead it just jumps to the solution without any context. 
+
+PRs without this will not be merged.
