 Vue components, Vue directives, Design Token and Scss files to build interfaces for demosPlan.
+
+### Using the local Docker container
+
+To have a consistent environment for building demosplan-ui, a Docker configuration exists.
+For Docker Compose 1, the syntax has to be adapted to `docker-compose` instead of `docker compose`. 
+The below commands use Docker Compose 2 syntax.
+
+```shell
+# Start the container
+docker compose -f docker-compose.local.yml up -d
+
+# Shell into the container
+docker compose -f docker-compose.local.yml exec demosplan_ui_local sh
+
+# Stop container
+docker compose -f docker-compose.local.yml down
+```

docker-compose.local.yml
