+This folder contains a Docker image to allow the building of
+`afl-frida-trace.so` using the `many-linux` docker image. This docker image is
+based on CentOS Linux 5. By building `afl-frida-trace.so` for such an old
+version of Linux, given the strong backward compatibility of Linux, this should
+work on the majority of Linux environments. This may be useful for targetting
+Linux distributions other than your development environment.
