 ## Overview
 
-This package brings into R the hydrological modelling tools developed at INRAE-Antony ([Catchment Hydrology research group](https://webgr.inrae.fr/en/home/) of the HYCAR Research Unit, France), including rainfall-runoff models (**GR4H**, **GR5H**, **GR4J**, **GR5J**, **GR6J**, **GR2M**, **GR1A**) and a snow accumulation and melt model (**CemaNeige**). Each model core is coded in Fortran to ensure low computational time. The other package functions (i.e. mainly the calibration algorithm and the computation of the efficiency criteria) are coded in R.

 # Introduction
 
-**airGR** is a package that brings into the [**R software**](https://cran.r-project.org/) the hydrological modelling tools used and developed at the [Catchment Hydrology Research Group](https://webgr.inrae.fr/en/home/) at [INRAE (France)](https://www.inrae.fr/en), including the [**GR rainfall-runoff models**](https://webgr.inrae.fr/en/models/) and a snowmelt and accumulation model, [**CemaNeige**](https://webgr.inrae.fr/en/models/snow-model/). Each model core is coded in **Fortran** to ensure low computational time. The other package functions (i.e. mainly the calibration algorithm and the efficiency criteria calculation) are coded in **R**.

Each model core is coded in **Fortran** to ensure low computational time. The other package functions (i.e. mainly the calibration algorithm and the efficiency criteria calculation) are coded in **R**. 
 
 
 The **airGR** package has been designed to fulfill two major requirements: to facilitate the use by non-expert users and to allow flexibility regarding the addition of external criteria, models or calibration algorithms. The names of the functions and their arguments were chosen to this end. **airGR** also contains basics plotting facilities.
