 ### Collecting statics for production:
 
+We use scss in the project. In development environment (DEBUG=True), scss is compiled every time the file is needed. For production, it assumes you have already compiled every files and to do so, you need to use the following commands : 
+
 ```
-./manage.py collectstatic
-./manage.py compilestatic
+./manage.py collectstatic # To collect statics
+./manage.py compilestatic # To compile scss in those statics
 ```
