-Threadless I/O
+
+## Concurrent I/O without threads
+
+`threadless.io` will present multiple mechanisms to perform I/O operations concurrently without threads. Eventually, this will include the following:
+* Event loops
+ * `select`
+ * `epoll`
+ * `kqueue`
+* Asynchronous callback-based I/O
+* Psuedo-blocking I/O with coroutines
