+This crate provides fuzzers based on [libfuzzer](https://llvm.org/docs/LibFuzzer.html).
+
+Available fuzzers:
+
+* packet\_recv\_client: Processes a single incoming packet (including frames) at
+  a time from the client side.
+
+* packet\_recv\_server: Processes a single incoming packet (including frames) at
+  a time from the server side.
