+# About the API
+
+## Prerequisite
+
+Current API was built throught Flask framework. In order to launch Flask server, some dependencies
+are needed, and should be installed (see requirements.txt)
+
+## API using
+
+Of course, you need to launch the flask server. On root folder, launch app.py.
+
+### First way : throught script
+
+Always on the root, a script called *launch_dummy_payload.py* init a request attempt to the server. To use it,
+just set the path to your file on the variable file_path, then launch it on CLI.
+
+### Second way : curl command
+
+Less convenient, curl command could be use, like this : *curl -X POST http://127.0.0.0:8888/production_plan -H "Content-Type: application/json" -d your_json_values*. Keep in mind that is not the most convenient way for large set of data. In this case, use the first option.
+
+## Interesting upgrade
+
+### CO2 cost inclusion
+
+Could be interesting to add in merit order this cost
+
+### Production quantity order
+
+Include production qty in using order, after cost;
+By instance, producing load of 400 with two powerplants (efficienty and cost equals) pmin and pmax respectively at 100/300 and 200/450.
+It makes sens to use second before, to avoid two powerplants activation (first cannot take the load completely, second is required,
+which oversize the asked load: 300 + 200 > 400).
