+### Exposing variables to BMI interface
 
 The variables which are exposed to the Python BMI are defined in `STEMMUS_SCOPE_exe.m`.
 To add more variables, update the `bmiVarNames` variable.
-After this, you will need to update the BMI in [PyStemmusScope](https://github.com/EcoExtreML/STEMMUS_SCOPE_Processing/) so it can make use of these exposed variables.
