+### End-to-end deployment guides
+
+The Defender for IoT documentation now includes a new **Deploy** section, with a full set of deployment guides for the following scenarions:
+
+- [Standard deployment for OT monitoring](/ot-deploy/ot-deploy-path.md)
+- [Air-gapped deployment for OT monitoring with an on-premises sensor management](ot-deploy/air-gapped-deploy.md)
+- [Enterprise IoT deployment](eiot-defender-for-endpoint.md)
+
+For example, the recommended deployment for OT monitoring includes the following steps, which are all detailed in our new articles:

+
+The step-by-step instructions in each section are intended to help customers optimize for success and deploy for Zero Trust. Navigational elements on each page, including flow charts at the top and **Next steps** links at the bottom, indicate where you are in the process, what you’ve just completed, and what your next step should be.
+
+For example:
+ 
+:::image type="content" source="../media/deployment-paths/progress-network-level-deployment.png" alt-text="Diagram of a progress bar with Site networking setup highlighted." border="false" lightbox="../media/deployment-paths/progress-network-level-deployment.png":::
