First off, just claim 15 provinces. Pick a color and a name. The game begins in the winter of the year 0.
Now, the actual rules of the game are quite simple. Every province produces 1, 3, or 5 supply it will be marked on the map, after signups are closed. Supply is important. Every army requires 1 supply to function at full effectiveness: if it has no supply, it will fight with a 50% combat malus. You can also use 2, 4, or 8 supply to give your units a 25%, 50%, and 75% combat boost respectively. A unit costs 1 supply to build, and you can order for certain units not to receive supply for that turn. All units get an automatic +25% defensive bonus.
An army can move twice a turn, but can't attack then move or move then attack. The arrows in the sea are strait crossings, going both ways (thanks to Sone for making them)
The game has 4 turns per year. Summer, spring, autumn, winter. In winter, you cannot strengthen units being used for offensive purposes. In spring, all units receive an additional +25% defensive bonus. In summer, unit strengthening requirements are halved (1 extra supply for a +25% combat boost, for instance). Autumn has no bonuses or maluses.
Supply lines are special. You have to have a direction route from your supply producing provinces to the armies receiving those supplies, or they won't get them; if an army is encircled, the only supply it will get is from the province it's in (so if 2 armies get locked in a 1 supply province, only 1 will be fully supplied. Likewise, a surrounded province can't provide supply to armies outside of it
