+# Docker Installation
+
+Docker is a software development container tool that combines software and its dependencies into one standardized unit that contains everything needed to run it. This helps us to avoid problems with dependencies and makes installation easier.
+
+## General Installation of Docker
+
+There are [sevaral ways to install Docker CE](https://docs.docker.com/install/) on your computer or server.
+
+{% tabs %}
+{% tab title="Docker Desktop macOS" %}
+
+Follow these instructions to [install Docker Desktop on macOS](https://docs.docker.com/docker-for-mac/install/).
+
+{% endtab %}
+{% tab title="Docker Desktop Windows" %}
+
+Follow these instructions to [install Docker Desktop on Windows](https://docs.docker.com/docker-for-windows/install/).
+
+{% endtab %}
+{% tab title="Docker CE" %}
+
+Follow these instructions to [install Docker CE](https://docs.docker.com/install/).
+
+This is a great option for Linux users.
+
+{% endtab %}
+{% endtabs %}
+
+Check the correct Docker installation by checking the version before proceeding. E.g. we have the following versions:
+
+```bash
+$ docker --version
+Docker version 18.09.2
+$ docker-compose --version
+docker-compose version 1.23.2
+```
+## Install Nitro with Docker
+
+Run the following command to install Nitro as a Docker container. This installation includes Neo4j.
+
+The installation takes a bit longer on the first pass or on rebuild ...
+
+```bash
+$ docker-compose up
+
+# rebuild the containers for a cleanup
+$ docker-compose up --build
+```
+
+### Seed Neo4j in Docker
+
+To seed the Neo4j database with default data, that GraphQL requests or playing with our GraphQL Playground returns anything else than an empty response, run the command.
+
+Run the following command to seed the Neo4j database with default data requested by Nitro-Web through GraphQL or when you play with our GraphQL playground.
+
+```bash
+# open another terminal
+
+# create indices etc.
+$ docker-compose exec neo4j migrate
+
+# seed database
+$ docker-compose exec backend yarn run db:seed
+```
+
+#### Wipe out Neo4j database in Docker
+
+To wipe out your neo4j database and delete the volumes send command:
+
+```bash
+# open another terminal and run
+$ docker-compose down -v
+```
