Hamachi Minecraft server: How do I do it?

Download Logmein Hamachi and install it - https://secure.logmein.com/products/hamachi/download.aspx
Click the power button once it is opened.
Make an account or whatever, name your system I think, I forgot this step.
Go to Network > Create a new network
Enter the Network ID (login your friends will use) and password you want
Your friends will download it, open it, click the power button, then go to Network > Join a network > Enter your Network ID and password, and then you guys will be in together.
Go to the Minecraft.net website
Click "Download it here" on the bottom right of the screen
Click and download "minecraft_server.1.7.4.exe"
Put it in a folder on your desktop
Run it while its in the folder
Close the window that pops up once it is done loading and creating the server
Re-open it, and your server's up!
Now, the IP your friends join is not YOUR Ip address, it is the Hamachi one. Where you/they go to find this is next to your name in the list of people in your Network group on the Hamachi window.
You're all ready to play now!
