# Prerequisites

**No-Go Zones:** Keep it out of Professional and Group Edition Orgs, like avoiding pineapple on pizza. \
\
**Peek-a-Boo Files**: Make sure files aren't playing hide and seek; enable them in settings! \
\
**Test Before you Fest:** Sandbox it before you plant it in production. No take-backsies! \
\
**Techie Stuff for 3.47+:** Post version 3.47, it's gadget time - set up a connected app, auth. provider and named credentials for the cool features.
