 The MOSAIC R package is designed to be used within a triad of Github repos where all functions are documented here at [MOSAIC-pkg](https://github.com/InstituteforDiseaseModeling/MOSAIC-pkg). The package downloads and processes all required data to be saved in [MOSAIC-data](https://github.com/InstituteforDiseaseModeling/MOSAIC-data) and prepares model quantities to run MOSAIC which are saved in [MOSAIC-pkg/model/input](https://github.com/InstituteforDiseaseModeling/MOSAIC-pkg/model/input). The package also produces all figures and tables used to make the documentation located at [MOSAIC-docs](https://github.com/InstituteforDiseaseModeling/MOSAIC-docs).
