There is no "starter kit" to bootstrap a new country, but the project architecture is designed to clearly separate the core engine from the modeled country. As this question has occured many times, we're certainly going to work on this topic and add a chapter to the documentation "Howto bootstrap a new country". For now starting a new country consists of creating a new repository like openfisca-<country_name>, implement what we call entities (ways to group people together like households, families, etc.) and implement the formulas corresponding to the legislation taxes and/or benefits you want to compute. This involves a lot of reverse-engineering work! If someone is interested, please contact us by opening a thread on the forum (https://forum.openfisca.fr/) or a GitHub issue (https://github.com/openfisca/openfisca-core/issues)

It's used today in France for notably : - estimating the taxes on salaries eg. before hiring (1) - estimating one's (as a citizen) social benefits on a centralized web page (2) - for various economic studies (where the numpy implementation helps working on large inputs) The core (https://github.com/openfisca/openfisca-core) package defines abstract structures used primarily but not specific to the France-specific package (-france), where the law is coded. Unfortunately, I don't think there is a way to bootstrap a new country (eg. generating templates for different kinds of taxes). -tunisia is the second country implemented, but much less maintained. "Extensions" enable local specifics to be added (e.g. specific to Paris). "Reforms" enable the simulation of experiments (e.g. simulating a basic income). (1) http://sgmap.github.io/cout-emba
