+
+Clone repository
+```
+git clone https://gitea.ekirin.com/Intis/prezentacija-komponiranje.git
+cd prezentacija-komponiranje
+```
+
+Start docker compose with all containers:
+```
+docker compose up -d
+```
+
+Wait until docker images are built and containers starts.
+
+Browse to [Local frontend application on port 8080](http://localhost:8080)
+
+List running containers:
+```
+docker compose ps
+```
+
+Attach to docker compose output:
+```
+docker compose logs -f
+```
+
+Stop running containers:
+```
+docker compose down
+```
+
+### Run on host network
+
