 ## OpenAPI 3.0 Generated Flask project
 
-All the routes are defined in 'project/api' folder. 
+The code was originally created by exporting the API from Postman. Selecting the API on the left (root element) the code generation icon becomes visible on the right.
+
+![image](../../docs/export_flask_project.png)
+
+If the API gets updated I think it makes most sense to export again into a API helper branch and then merge this branch back into the project. Please do not forget to update the [index.yaml](../../misc/index.yaml) file.
+The branch is named yaml_export.
+
+All the routes are defined in 'project/api' folder.
 Each route parses the request and calls the corresponding function in the 'project/impl' directory passing all the parameters and request body as function arguments.
 
 To run this project:
-```
+
+```bash
 pip install -r requirements.txt
 export FLASK_APP='BreCal'
 export FLASK_ENV=development
 flask run
-```
