+.Sh DESCRIPTION
+See your system's manual page for
+.Xr queue
+for additional information. ck_queue is a queue.h-compatible
+implementation of many-reader-single-writer queues. It allows
+for safe concurrent iteration, peeking and read-side access
+in the presence of a single concurrent writer without any
+usage of locks. In many cases, adoption of ck_queue will
+simply require prefixing all queue operations with CK_.
