 > Disclaimer: This repository contains a demo of `Zava AI Shopping Assistant`, a multi-agent system implementing Agent-to-Agent (A2A) protocol for e-commerce. It features a fully automated `"Zero-Touch" deployment` pipeline orchestrated by Terraform, which `provisions infrastructure, ingests data, creates specialized AI agents with delegation patterns in MSFT Foundry, and deploys the complete A2A application stack.` Feel free to modify this as needed, it's just a reference. Please refer [TechWorkshop L300: AI Apps and Agents](https://microsoft.github.io/TechWorkshop-L300-AI-Apps-and-agents/), and if needed contact Microsoft directly: [Microsoft Sales and Support](https://support.microsoft.com/contactus?ContactUsExperienceEntryPointAssetId=S.HP.SMC-HOME) for more guidance. There are tons of free resources out there, all eager to support!
