     There is a builtin command that can somewhat fake a datalogger::
 
-        docker exec -it dsmr-app poetry run /app/manage.py dsmr_fake_datasource --with-gas --with-electricity-returned
+        docker exec -it dsmr-app poetry run /usr/src/app/manage.py dsmr_fake_datasource --with-gas --with-electricity-returned
 
 It will generate random data every second in a certain pattern and should be fine for basic testing. 
 
 Please note that it only inserts unprocessed readings, so you'll still have to run the following command to have the readings processed::
 
-    docker exec -it dsmr-app poetry run /app/manage.py dsmr_backend --run-once
+    docker exec -it dsmr-app poetry run /usr/src/app/manage.py dsmr_backend --run-once
