 ### What is the "optirrigBEET" package ?
 
-The optirrigBEET package in R is a specialized adaptation of the Optirrig model, originally developed as part of the optirrigCORE package. Its main objective is to optimize the simulation of sugar yield for sugar beet crops. This package facilitates the extraction and formatting of observation data required by the model, as well as the integration of specific descriptions of plants, soil, and yields relevant to sugar beet cultivation.
+The **optirrigBEET** package in R is a specialized adaptation of the Optirrig model, originally developed as part of the optirrigCORE package. Its main objective is to optimize the simulation of sugar yield for sugar beet crops. This package facilitates the extraction and formatting of observation data required by the model, as well as the integration of specific descriptions of plants, soil, and yields relevant to sugar beet cultivation.
 
 As an adaptation of optirrigCORE, optirrigBEET inherits its core functionalities and relies on optirrigCORE as a dependency. It supports various analytical methods, such as Ex-Post and Ex-Ante analyses, with the aim of designing optimized irrigation schedules based on precise criteria for sugar beet production. The package includes all necessary calculation tools to describe biophysical processes with a generalist approach, while also catering to the specific needs of sugar beet cultivation.
