# RuleSetContent

The rule set determines the two key elements of a match: your game's team structure and size, and how to group players together for the best possible match.

For example, a rule set might describe a match like this:
- Create a match with two teams of five players each, one team is the defenders and the other team the invaders.
- A team can have novice and experienced players, but the average skill of the two teams must be within 10 points of each other.
- If no match is made after 30 seconds, gradually relax the skill requirements.
