Cisco Router - IOS Version 15: How To Upgrade/Add A License File For More Features

I had to do this today on a router because I needed VPN capability, but I didn't have it because we had not bought a security license on this particular 2901 router.  I had to buy a license and get it sent electronically (because that is the fastest way) so I could get this done today.  Well, here are the steps I had to take to get this done:
Get the PAK key.
Go to the Cisco license page and login.
Put the PAK key in and get add your UDI Product and Serial ID.  Find this by doing a 'show license UDI' command on the router.
Download your license.
TFTP the license to your router flash.
Use the 'license install flash:licensename.lic' to install the license.
Reboot the router.

It looked like this when installing the license:
2901#license install flash:licensename.lic
Installing licenses from "flash:licensename.lic"
Installing...Feature:securityk9...Successful:Supported
1/1 licenses were successfully installed
0/1 licenses were existing licenses
0/1 licenses were failed to install

Verify with the 'show license all' command:
2901#sh license all
