It's more like a Manual(no, it doesn't have 100 pages .. yet) and I will send it to all players once the game starts.
However, if there is some part you want to know now then just ask.

Basically, hexes represent provinces. They are gathered into regions.
Each hex gives you fixed amount of money that can be increased with cities/ports and regional bonuses.
Hexes also show you how many units you can have. At the start of the game Savoy can have 5 but France 47 units.
Your Armies can move as fast as their slowest member. So, having artillery with you will slow your movement a lot since it can move only 1 hex per Order while Infantry can move 2, Cavalry 3-4 and Ships from 4 to 6.
This brings to Orders. Each game turn lasts 6 seasons. It's good if people could send their orders like this:
Orders
1. Move Royal army north 2 hexes.
2. Build City in Aquitane on hex 4
3. Send spy to Austria to Gather Info on their Economy.
4. Increase Royal Court
5. Recruit new General
6.Convert Region – Provence
Each point represents one season. Under these you can add what ever info you think is important(alliances etc).
Orders are carried out simultaneously.
Anything else you like to know?
Trust me, it's not that difficult. Once you start playing this will become really easy.
I also leave a lot of room for RP. You want to name your cities, generals or what ever? Then name them!

I'll keep the sign ups open for another day or two.
