+
+## What is included?
+
+The image is based on the Microsoft Hosted Ubuntu 22.04 image and contains the
+all tools included in the Microsoft Hosted image that include a license that
+allows redistribution. The image is built using the same scripts as the
+Microsoft Hosted image and is updated regularly. A 
+[full list of included tools](https://github.com/cloudyspells/ado-agent-ms-stack/wiki/Ubuntu2204-Readme)
+is available in the project wiki.
+
+## How to use it?
+
+The image is available in the Azure Marketplace and can be used in Azure
+DevOps pipelines as a self-hosted agent. The image is available in the
+all regions where Microsoft Hosted agents are available. You can also build
+your own image using the scripts in the GitHub repository. Building your own
+image is useful if you want to add additional tools or customize the image
+further.
+
+## What are the advantages?
+
+When connecting to a private network is required, the Microsoft Hosted agents
+cannot be used. This is a common requirement in many projects. As your
+organization grows, the need for various build and deployment tools increases.
+Building and maintaining your own agent images is a lot of work. Using the
+pre-built image removes the need to build and maintain your own images as it
+includes most popular tools. The image is also updated regularly with the
+latest versions of the tools.
