+# go-sleep sleeps for some duration
+
+This unix tool is a thin wrapper around `time.Sleep()`.
+It aims to provide a portable way to sleep for an amount of time that
+need not to be a number of seconds.
+
+See https://godoc.org/time#ParseDuration for how the duration can be
+specified.
+
+### Install
+
+```sh
+go install github.com/chriscool/go-sleep
+```
+
+### Usage:
+
+```
+> go-sleep
+Usage: go-sleep <duration>
+Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
+See https://godoc.org/time#ParseDuration for more.
+> time go-sleep 100ms
+
+real    0m0.104s
+user    0m0.000s
+sys     0m0.007s
+```
