+This directory includes a few programs that demonstrate how to use io_uring
+in an application. The examples are:
+
+io_uring-cp
+	A very basic io_uring implementation of cp(1). It takes two
+	arguments, copies the first argument to the second. This example
+	is part of liburing, and hence uses the simplified liburing API
+	for setting up an io_uring instance, submitting IO, completing IO,
+	etc. The support functions in queue.c and setup.c are straight
+	out of liburing.
+
+io_uring-bench
+	Benchmark program that does random reads on a number of files. This
+	app demonstrates the various features of io_uring, like fixed files,
+	fixed buffers, and polled IO. There are options in the program to
+	control which features to use. Arguments is the file (or files) that
+	io_uring-bench should operate on. This uses the raw io_uring
+	interface.
+
+liburing can be cloned with git here:
+
+	git://git.kernel.dk/liburing
+
+and contains a number of unit tests as well for testing io_uring. It also
+comes with man pages for the three system calls.
+
+Fio includes an io_uring engine, you can clone fio here:
+
+	git://git.kernel.dk/fio
