 # About Microsoft
 
-Open Source enables Microsoft products and services to bring choice, technology
-and community to our customers.
+Microsoft is proud to be back as a returning sponsor of EuroPython this year.
+We’re excited to continue supporting the Python community by building tools and
+services that developers rely on every day, whether you're working on data
+science projects, web apps, or exploring AI.
+
+This year, we’re committed to helping Python developers succeed with AI app
+development. Our new AI extension pack in VS Code brings together tools like
+GitHub Copilot, the AI Toolkit, and Azure AI Foundry to support you through the
+development lifecycle—from building and testing to deploying intelligent apps.
+These tools are designed to help you move quickly, whether you’re experimenting
+locally or scaling in the cloud. Explore Microsoft’s sessions and demos, and
+visit our booth to connect with the team and learn how we’re shaping the future
+of Python development.
