+Welcome to the documentation about the Arctic Observation Operator!
+===================================================================
 
-**! Please be careful when using the code !**
+The Arctic Ocean Observation Operator (ARC3O) computes brightness temperatures at 6.9 GHz, 
+vertical polarization, based on climate model output. More information about the motivation, 
+structure and evaluation can be found in `Burgard et al., 2020a`_ and `Burgard et al., 2020b`_. 
 
-Especially, there might not be an error message when ran at another polarization or frequency than 6.9 GHz, vertical polarization,
-but the results have only be evaluated at that frequency and polarization!
+Currently, it is customized for output of the Max Planck Institute Earth System Model but can be 
+used for other models if the variable names are changed accordingly in the ARC3O functions.
 
-If you are interested in 6.9 GHz, vertical polarization, enjoy! :)
