Scoreboard Tutorial [video]

I've made a brief description on the new minecraft scoreboard that should make sense to you in a form of a video.

Questions?
Just ask me, and I'm sure I can answer them!

Snapshot:
www.mojang.com (need it)

Slightly outdated video, so there are command to make teams and join teams ; )

Make Teams: scoreboard teams add.
Do this first!
Join em': scoreboard teams join
when you don't specify player, the command will apply to you
Style: scoreboard teams option
Values:

1. friendly fire:
true: The default setting, true, has no impact on PvP mechanics. When set to false, players on this team cannot harm each other with melee, bow, or Splash Potion of Harming attacks, but may still inflict negative status effects on each other.

2. color:
Will color the name of all players on this team in chat, above their head, on the Tab menu, and on the sidebar. Valid color values are "black", "dark_blue", "dark_green", "dark_aqua", "dark_red", "dark_purple", "gold", "gray", "dark_gray", "blue", "green", "aqua", "red", "light_purple", "yellow", and "white". Other valid values are "reset" (names show in default color and formatting), "obfuscated" (same as effect seen in obfuscated parts of the End Poem), "bold", "strikethrough", "underline", and "italic". See Formatting Codes for information about how these will appear.
