+# Chapter 7
+
+Code accompanying Chapter 7 of the book [Data Pipelines with Apache Airflow](https://www.manning.com/books/data-pipelines-with-apache-airflow).
+
+## Contents
+
+
+## Usage
+
+To get started with the code examples, start Airflow with Docker Compose with the following command:
+
+```bash
+docker-compose up -d
+```
+
+The webserver initializes a few things, so wait for a few seconds, and you should be able to access the
+Airflow webserver at http://localhost:8080.
+
+To stop running the examples, run the following command:
+
+```bash
+docker-compose down -v
+```
