 * graphPaname
 
-This project aims to gather information about the smart city of Paris and
-organize it in different plots and tables.
+graphPaname is a system that collects real-time data, relevant to the COVID-19 epidemic de-escalation,  from the city of Paris.
+
+It works with 4 datasets about the de-escalation:
+
+- Retailers with home delivery
+- Additional parking places in relay parkings (parkings connected to public transportation)

+For each dataset, we offer a table with the data, and a map of Paris with markers.
