+# Deprecation
+
+All projects have a useful lifespan. Quail was born during a time when accessibility
+testing, as a discipline, was maturing. There were numerous teams building solutions
+in parallel -- Quail was just one of these. In the end, we were all orbiting around
+the same general approach. Technology may have been a distinguishing factor a couple
+years ago, but even these advantages have largely dissolved as solutions have evolved
+and improved over time.
+
+Given the realities of the market and the limited time that the Quail team can
+devote to this project, we are initializing deprecation for this project. Folks
+are welcome to fork it or volunteer to maintain it, but realistically, there are
+better options out there.
+
+If you are looking for one, we recommend [aXe: the Accessibility Engine](https://github.com/dequelabs/axe-core) by [Deque Labs](https://github.com/dequelabs).
