# Non-Compatible Salesforce Editions S-Docs requires the Unlimited Edition (UE), Enterprise Edition (EE), Performance Edition, or Developer Edition (DE). It is not compatible with Professional Edition (PE) or Salesforce Essentials because neither edition has all the basic objects and they are limited on Apex functionality. We have had support requests from people who have successfully installed S-Docs in their Professional Edition org and even generated documents. But when things get even slightly complex, things start going sideways and we can't support it. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
