The first step is to get the Raspberry Pi ready to SSH in. This allows us to do all the typing on a bigger, more comfortable computer. Its not essential but we found it pretty darn handy!

Setting up the pi to allow remote log-ins only has to be done once!

• Be sure to have a SD card with a working Linux distribution (we wont cover this here)
• Be sure to have a micro USB cable to power the Pi
• Connect a monitor (Television or HDMI), USB keyboard, and working Ethernet cable to the Pi

Power up the Pi. Make sure you can start up the Pi, see the white loading text and the login: prompt. Login with user name pi and password raspberry
Then type in the following commands in order

1. sudo bash
   
2. ssh-keygen -t rsa (hit enter twice when prompted)
3. mv /boot/boot_enable_ssh.rc /boot/boot.rc
   

Then reboot by typing in reboot. Now look for the IP address on boot up. Its circled in red above. 
Now you can use an SSH client on a windows/mac/linux computer (there are lots of free ones out there) and log in to that ip address (for example, 192.168.1.106 or whatever yours is) with the same username pi and password raspberry

Now you can control the Pi from your desktop computer! Remember that this IP address can only be accessed from within the local network (that is, your home or office with a shared router) - you can't get to it from the outside world if you have a 192. or 10.  IP address. Ask your friendly IT/Network admin if you have questions about this.
