+# AVD and CVaaS Provisioning Demo
+
+## How to Run the Demo
+
+> **WARNING**: A CVaaS instance is required to run this demo.
+
+The lab network can be created using Containerlab inside the provided Dev Container.  
+The Dev Container can be started on any machine with Docker using [supporting tool](https://containers.dev/supporting) (for example [VSCode](https://code.visualstudio.com/)) or as a [Codespace](https://github.com/features/codespaces) on forked Github repository.
+
+Before you start the Dev Container, you must set following environment variables on your system:
+
+- ARTOKEN - token required to download cEOS image from [arista.com](https://www.arista.com/). You can find it in your arista.com profile settings if it's enabled for your account.
+- CVTOKEN - CVaaS streaming token. This token must be created in advance and remain valid during the demo runtime.
+- CV_API_TOKEN - CVaaS API token. This token must be created in advance and remain valid during the demo runtime.
+
+> **NOTE**: When using Github Codespaces, these variables must be set in `Settings > Secrets and variables > Codespaces`
+
+## Security Considerations
+
+> **WARNING**: Make sure that nobody else has access to your Codespace / Container and that it is destroyed after the demo as environment variables will be cached in the container memory.
