Great book, great rules

I am new to tabletop RPG, and as a master of the game.
However, thanks to this book I could carry some fun family parties and I intend to lead as with my club JDR.
For now, in taking care, the book object itself seems to have no default.

The rules are fully in English but the information is relatively simple to follow (a moderate level in English is still required).
At my level of relative novice as a player and GM, rules seem interesting, uncomplicated and yet sufficiently open to be able to judge each possible situation.
Considering the PDF supplements available on the website of Wizards of the Coast, it will launch its own scenario / campaign effectively and fairly easy.
