+
+3. Quick Start
+==============
+
+You need a version 1.0 or later of v4l2-ctl, available from:
+	git://git.linuxtv.org/v4l-utils.git
+
+$ sudo modprobe bcm2835-v4l2
+
+Turn on the overlay:
+
+$ v4l2-ctl --overlay=1
+
+Turn off the overlay:
+
+$ v4l2-ctl --overlay=0
+
+Set the capture format for video:
+
+$ v4l2-ctl  --set-fmt-video=width=1920,height=1088,pixelformat=4
+
+(Note: 1088 not 1080).
+
+Capture:
+
+$ v4l2-ctl --stream-mmap=3 --stream-count=100 --stream-to=somefile.h264
+
+Stills capture:
+
+$ v4l2-ctl  --set-fmt-video=width=2592,height=1944,pixelformat=3
+$ v4l2-ctl --stream-mmap=3 --stream-count=1 --stream-to=somefile.jpg
+
+List of available formats:
+
+$ v4l2-ctl --list-formats
