2. Connect and play
3. Summary of global hotkeys

1 - Preparation
Before being able to play, you must have an account on the website.
If it is not the case, go to http://qcsalon.net/en/register or click on the « create account » button on first run of the program.
Choose an username and a password. You will then receive an e-mail containing a validation link which will definitely activate your account.
All that should not take you more than 5 minutes.

2 - Connect and play
At program start, enter your username and password in the corresponding edit zones, then press enter or click on the « connect » button.
You will then be inside the playroom and you will be able to start playing, either by creating a new table and waiting for your friends, or by joining an existing one.
The rest of the interface works essentially with menus where you make your choice with arrow keys and enter.
There are also many hotkeys, specific to the game you are playing, or in general in the playroom.

To look at the game rules and specific hotkeys of a particular game, go to http://qcsalon.net/ in the corresponding subtopic, or press Ctrl+F1 to directly open the game rule page during a game.

It doesn't need to be updated. And it helps of course, if he wants to ask us. Personally I'm willing to help as I can
