+### Enabling SSH on your Pi
+SSH access is turned of by default for security. We need to do a simple extra step to enable it.  
+
+The boot partition on a Pi should be accessible from any machine with an SD card reader, on Windows, Mac, or Linux. If you want to enable SSH, all you need to do is to put a file called ssh in the /boot/ directory. The contents of the file don’t matter: it can contain any text you like, or even nothing at all. When the Pi boots, it looks for this file; if it finds it, it enables SSH and then deletes the file. SSH can still be turned on or off from the Raspberry Pi Configuration application or raspi-config; this is simply an additional way to turn it on if you can’t easily run either of those applications.

 Once that’s done, connect your RPi to a DHCP network with an ethernet cable and power it on.  Depending on your network configuration, you can login to your RPi using it's hostname "raspberry", or use a network discovery tool to find it's IP address. 
 We will use nmap to scan our DHCP IP range for all hosts that are up. Replace 10.0.0.1/24 with your IP address range. You can also check you router's settings to see all devices connected to your network and their IPs.
