[New Video] How to Build Your First RAG Agent with Agent Development Kit (ADK + Vertex AI RAG Service)

You can now build your own Retrieval-Augmented Generation (RAG) agent that answers questions using your documents from Google Drive—and it only takes a few minutes with Google’s Agent Development Kit (ADK).

In this brand-new tutorial, I’ll walk you through a complete ADK workflow that:

✅ Connects your agent to Google Cloud and sets up a knowledge base

✅ Uploads and manages your documents for smarter responses

✅ Instantly answers questions with citations from your actual files

✅ Expands easily with new docs to make your agent even more powerful

This is the perfect crash course if you're looking to break into real-world AI development and learn RAG from the ground up. And yes—I'm giving away the entire source code for free.
