What's a Port?
In this and the next appendix, you'll see references to network ports and Minecraft's
default port of 25565. A port is just an agreed-upon number that lets computers

with web servers.

And we're up and running!
Now tell your friends to download the same software and join your network
with the name you picked (like andys_minecraft_server ).
