Modding Techs

[AThousandYoung]

Hello,

I want to rewrite the tech tree. However there are so many entries for each tech; "Flavor", "TXT_KEY"... I don't know what to change and what not to. For example, let's say I want to have one of the first techs be called "Stoneworking I". This would lead to Stoneworking II and provide +1 food for unimproved animal plots, because early stone tools used for scraping meat from the bones of a big animal.

How do I make that happen?

Food is a yield.
stoneworking I is a tech prereq of stoneworking II.

I'm sure you will be able to found out.
