+# SIMDe Without Test Cases
+
+This repository contains only the core of
+[SIMDe](https://github.com/simd-everywhere/simde/simde).
+It is generated automatically for every commit to master, and is
+intended to be used as a submodule in projects which don't want to
+include the (rather large) test cases.
+
+All development work happens in the main repository, please do not
+file issues or create pull requests against this repository.
