+## Project Setup
+
+### Setup with [Docker](https://www.docker.com/get-started)
+
+1. `git clone https://gitlab.mi.hdm-stuttgart.de/jh257/hae.wtf.git`
+2. `cd hae.wtf`
+3. `docker-compose up`
+
+Now both the client and server containers should be running and you can start developing.
+
+**Note:** For local development you must also run `yarn install` in both the `client` and `server` folders.
+
+**Fixing issues with Docker:**  
+If you get errors about missing modules after adding a dependency try running `docker-compose down` **or** `docker-compose build` before running `docker-compose up`.
