-# ets_tutorial
-This repository contains an Enthought Tool Suite tutorial submitted for the 
-SciPy2019 conference.
+# Sharing your scientific tools: from a script to a desktop application
+This repository contains a GUI building and packaging tutorial using the 
+[Enthought Tool Suite](https://docs.enthought.com/ets/) accepted for the 
+SciPy2022 conference.
 
-## Tutorial
+## Tutorial summary
 
-## Requirements
+In this workshop, we will learn to embed scientific tools into a robust 
+scientific application that can scale from a tiny UI to a large platform. As an 
+example, attendees will build an image browser application (including 
+face-detection capabilities), allowing users to search through their pictures, 
+based on various criteria. We will start from a simple jupyter notebook and 
+progressively turn it into a complete application using Matplotlib and several 
+packages from the Enthought Tool Suite such as Traits, TraitsUI and Pyface. In 
+the process, attendees will learn how to design clean, maintainable and 
+scalable applications, and package them into an installer.
