+# Open Lobby Demo
+
+Demo of [Open Lobby Server](https://github.com/openlobby/openlobby-server) and
+[Open Lobby App](https://github.com/openlobby/openlobby-app).
+
+You need [Docker Compose](https://docs.docker.com/compose/) for running this
+demo.
+
+## Run
+
+Clone this repository and then you can:
+- Run it: `make run`
+- Stop it: `make stop`
+- Stop and/or remove all data: `make destroy`
+
+It runs:
+ - Elasticsearch on port `9200`
+ - Open Lobby Server on port `8010` - GraphQL API endpoint and GraphiQL
+   interface are at `http://localhost:8010/graphql`
+ - Open Lobby App on port `8020` - web application is at `http://localhost:8020`
+
+You may notice some errors and crashes if you access it immediately because
+Elasticsearch starts slowly. But it should recover and eventually it will be all
+running fine.
