+Configuration for Docker Compose
+--------------------------------
+
+Configuration of the `/deployment` Docker Compose setup consists of
+three port numbers.
+
+* `ULOCOMPOSE_DBPORT` is the port the GraphDB instance listens on.
+
+* `ULOCOMPOSE_COLLECTPORT` is the port the collector listens on.
+
+* `ULOCOMPOSE_APPPORT` is the port the application listens on.
+
+Configuration for Local Installs
+--------------------------------
 
 The `src/ulo-storage-applications` web interface listens on
 `0.0.0.0:7400`. If you wish to change this, you can set the

deployment/.env

+ULOCOMPOSE_DBPORT=7200
+ULOCOMPOSE_COLLECTPORT=7300
+ULOCOMPOSE_APPPORT=7400
