+## Quick start with Docker
+
+```shell
+git clone https://github.com/adhocteam/pushup.git
+cd pushup
+make build-docker
+```
+
+Then create a scaffolded new project in the current directory:
+
+```shell
+docker run --rm -v $(pwd):/usr/src/app --user $(id -u):$(id -g) pushup new myproject
+cd myproject
+docker run --rm -v $(pwd):/usr/src/app --user $(id -u):$(id -g) -p 8080:8080 pushup run
+```
+
+See [Creating a new Pushup project](#creating-a-new-pushup-project) for more information.
+
 ## Getting started
 
 To make a new Pushup app, first install the main Pushup executable.
