+# Caluma: Guide
+
+## About this guide
+
+Goals:
+- get a simple app running
+- understand concepts behind caluma
+  - build a form
+  - design a simple workflow
+
+## Installation
+
+To install Caluma, you'll need to have [Docker]() and [docker-compose]() installed on your system.
+
+Afterwards, create a new directory for your project, copy our [example docker-compose.yml file](https://github.com/projectcaluma/caluma/blob/master/docker-compose.yml) into it and finally run the following command:
+
+Per default, Caluma is running with production settings. To bypass the security-related configuration steps needed for a prodoction system, create a new file called `docker-compose.override.yml` with the following content:
+
+```yml
+version: "3.4"
+services:
+  caluma:
+    environment:
+      - ENV=development
+```
+
+Afterwards, start the containers by running
+
+```bash
+docker-compose up -d
+```
+
+You can now access [GraphiQL](https://github.com/graphql/graphiql) at [http://localhost:8000/graphql](http://localhost:8000/graphql). We'll use graphiql to interact with the Caluma service in the coming sections.
