+# Sleep container image
+
+A container image that just sleeps 10 on repeat (will output the sleep command
+so you know it's running).
+
+## Usage
+
+For interactive use, specify `-it` so you ctrl+c the container:
+
+```
+docker run -it --name sleep registry.shore.co.il/sleep
+```
+
+You can also specify a more complex command:
+
+```
+docker run -it --name sleep registry.shore.co.il/sleep date '&&' sleep 5
+```
