 # API Enhancement Proposals
 
-The [AEP Project](https://aep.dev) is an API design specification and ecosystem
-of clients and tooling for protobuf and HTTP REST APIs.
+**TL;DR:** AIPs are lots of documents on how we do APIs.
 
 ## Overview
 
-See [GOVERNANCE.md](./GOVERNANCE.md).
+AEP stands for **API Enhancement Proposal**, which is a design document
+providing high-level, concise documentation for API development. The goal is
+for these documents to serve as the source of truth for API-related
+documentation at Thryv and the way API teams discuss and come to consensus on
+API guidance. The program is named and styled after Python's enhancement
+proposals (PEPs) which have seemed to work pretty well over the years.
