+# Deployment Overview
+
+The MapSwipe Back-End is deployed using Docker.
+Every part of the back-end has a Dockerfile.
+All parts/ Dockerfiles come together in the docker-compose file.
+
+To setup the whole ecosystem of MapSwipe Workers it is easier to first make sure every part is configured and all keys are in place.
+
+MapSwipe utilizes a bunch of Google Cloud services:
+
+- [Firebase](https://firebase.google.com/) project with Realtime Database and Functions
+    - Create a project
+    - Create a database: `> Develop > Database > Create Database`
+- [Google Cloud Storage](https://cloud.google.com/storage/) for backup of Postgres
+
+[Configuration and Credentials]() describes all needed configuration and credentials.
+
+[Installation]() describes step-by-step how to setup the backend for the first time.
