 # Simulator package
 
-Here you can put the wrappers for simulator used with PET. 
+This folder contains simple models intended for testing the PET code. 
+For information about how to add wrappers for new simulators, see the repo: 
 
-You can build your wrapper (almost) any way you like, but you must follow the following rules:
-
-1. The wrapper must be a Class
-2. The Class must contain the following three methods:
-
-```
-__init__(self,input_dict):
-    # parse information from the input. 
-    # Needs to get datatype, reporttype and reportpoint
-```
-
-```
-Setup_fwd_run(self)
-   # do whatever initiallization you need.
-   # Useful to initiallize the self.pred_data variable.
-   # self.pred_data is a list of dictionaries. Where each list element represents
-   # a reportpoint and the dictionary should have the datatypes as keys. 
-   # Entries in the dictionary are numpy arrays.
-```
-
-```
-run_fwd_sim(self, state, member)
-  # run simulator. Called from the main function using p_map from p_tqdm package.
-  # Return pred_data if run is successfull, False if run failed.
-```
