+### Docker based Setup
+Use the following command to start all containers (First run takes a lot of time):
+
+    docker-compose up --build
+
+Afterwards the following services are available:
+
+  * Port 8080: ktor-server
+  * Port 8000: nlp_server
+  * Port 27017: MongoDB-Server
+
+To access the OpenAPI documentation of nlp_server open **http://localhost:8080/docs**.
+
+The following paths are mounted by default:
+
+  * nltk_data: to store nltk-data, e.g. big models, which we don't want to download every time we start our container.
+  * mongodb_data: stores the data of the mongodb container.
