+# Welcome to documentation repository for Confidential Containers 
+
+Confidential Containers is an open source community working to leverage 
+[Trusted Execution Environments](https://en.wikipedia.org/wiki/Trusted_execution_environment) 
+to protect containers and data and to deliver cloud native 
+confidential computing.
+
+Our key considerations are:
+- Allow cloud native application owners to enforce application security requirements
+- Transparent deployment of unmodified containers
+- Support for multiple TEE and hardware platforms
+- A trust model which separates Cloud Service Providers (CSPs) from guest applications
+- Least privilege principles for the Kubernetes Cluster administration capabilities which impact 
+delivering Confidential Computing for guest application or data inside the TEE.
