-## Developing the application (ie. express/React)
-1. Uncomment the pipeline-ui container from `docker-compose.yml`
-2. Find the IP of your machine with ie `ifconfig` or `ip addr`
-3. Run `export BACKEND_IP=192.168.1.10` where `192.168.1.10` is your main IP if the client
-2. Start logstash with `BACKEND_ENDPOINT=http://${BACKEND_IP}:8080/api/v1/receiveLogstashOutput docker compose up`
-3. In another terminal, start backend with `cd pipeline-ui/backend; npm run dev`
-4. In yet another terminal, start frontend with `cd pipeline-ui/frontend`
+## Contributing to the application (express/React)
+If you want to to develop the application you'll need a local development environment
+on your client. Follow these steps to get started:
+
+1. Find the IP of your machine with ie `ifconfig` or `ip addr`
+2. Run `export BACKEND_IP=192.168.1.10` where `192.168.1.10` is your main IP if the client
+3. Start logstash with `BACKEND_ENDPOINT=http://${BACKEND_IP}:8080/api/v1/receiveLogstashOutput docker compose up logstash`
+
+    *Note that some flavors uses `docker compose` instead of `docker-compose`*
+4. In another terminal, start backend with `cd pipeline-ui/backend; npm run dev`
+5. In yet another terminal, start frontend with `cd pipeline-ui/frontend`
 
 Now you can update the code freely and both backend and frontend should refresh automatically.
