 #### launcher.py
+This is the script to run to create the database from retrieved external data. The "writer.py" module is integrated within this one, creating a 
+log file with a short quantitative summary of the database's contents during construction. By default, the functions assume that the data
+has been processed and create the database automatically. Each function has a "preprocessing" boolean flag, that can be activated to repeat
+preprocessing for a given external source. If the user wants to update an already integrated external source, it can do so by running the launcher
+functions associated with that source (data will be duplicated in the Staging Area as intended, but not in the TRN Universal Graph unit).
+If the user has a file with the same structure as the file used to integrate the external source data in the TRN Universal Graph unit,
+there is no need to repeat preprocessing. If the user only has a newer version of the raw data retrieved from the external source, it is 
+mandatory to repeat the preprocessing stages (preprocessing=True).
