Colonizopedia is the in-game encyclopedia for Colonization and freecol. Here stands all facts about things that ain´t found in the manuals in a way to see them when you need them. A place to see what buildings, units, tiles and other stuff do and how they work so you later can use them in the right way. Observe that there´s no maximum use of the Colonizopedia so use it as much as possible when you are unsure of things so you learn about the game.
