One of the things you can see, if you go to the store page here and click on digital items is a strategy guide that you can purchase separately or get with certain pledge packages.
That being said, we don't know what it will contain.
CoE is not meant to be a game where min-maxing stats is encouraged (although players will always try) so giving numbers like how much skill gain you get from successfully grown crops isn't likely to be included and is likely going to be discovered via gameplay.
The studio has been pretty consistent about their desire to leave the fun of discovery to the players themselves (through experimentation and exploration). That being said, it stands to reason that some knowledge will already exist in the world, and so while it is unlikely that we are going to find formulas in a strategy guide or any other official documentation, there may be books and NPC's in the world from whom we can learn things.
