+# DuckDB
+
+DuckDB is an in-process SQL OLAP database management system. It is designed to
+support analytical query workloads and is optimized for fast query performance
+on large datasets. DuckDB can be embedded directly into applications, making it
+a popular choice for data analysis tasks in various programming environments.
+
+
+## What is it?
+
+1. `patients.ipynb`: A Jupyter notebook that demonstrates how to use DuckDB for
+   analyzing patient data. It includes examples of loading data and executing
+   SQL queries.
+1. `data/`: CSV files to use with the notebook.
