+## Data Collection
+
+Log into the Raspberry Pi and enter the following commands:
+
+	# Go to wherever you installed ffmpeg
+	cd /usr/src/ffmpeg
+
+	# Run ffmpeg. I have no idea how this command works since I copy-and-pasted it from some website off of Google
+	sudo ffserver -f /etc/ff.conf_original & ffmpeg -v quiet -r 5 -s 320x240 -f video4linux2 -i /dev/video0 http://localhost/webcam.ffm
+
+At this point the streaming video should be available at the URL below (although you probably won't be able to just open/view it with a web browser). Note that the IP will probably be different for you.
+
+	http://192.168.0.35/webcam.mjpeg
+
+## FAQ
+
+**Q:** How do I log into the Pi?
+
+**A:** By default the id is ***pi*** and the password is ***raspberry***. I usually ssh into mine using the "Terminal" application on my Mac. On Windows you could probably use Putty. See example command below. Note: your IP will probably be different.
+
+	ssh [email protected]
+
+**Q:** How do I find the IP address for my PI?
+
+**A:** There are probably multiple ways to do this, but whenever I connect my Raspberry Pi to a wifi network for the first time I always have to plug in my keyboard, mouse, and HDMI cable so that I can view the Pi on a monitor or TV. Then open up the Pi console and type the command below, which will print the IP to your console.
+
+	hostname -I
