# Introduction to fact-models

fact-models is the starting point for the standard analysis process. The downstream dependencies of fact-models are outlined in the diagram below.

fact-models contains a library of dhall configuration files that define Fact and Model information. These files are meant to be shareable and re-combinable.

fact-models also contains a haskell library of the same name that ingests the dhall package to create haskell types. These haskell types can then be imported into a project’s cohort building application.

See the user guide for information on defining fact and model information and using these definitions in downstream dependencies.

See the developer guide for information on contributing to the project.
