+# LangFlow Demo Codespace Readme
+
+These instructions will walk you through the process of running a LangFlow demo via GitHub Codespaces.
+
+## Setup
+
+### Create a Codespace in GitHub
+
+To setup the demo, simply navigate to the Langflow repo, click the "+" button, and select "Create new Codespace". This will automatically create a new codespace in your browser, which you can use for the demo.
+
+### Wait for everything to install
+
+After the codespace is opened, you should see a new Terminal window in VS Code where langflow is installed. Once the install completes, `langflow` will launch the webserver and your application will be available via devcontainer port. 
+
+Note: VS Code should prompt you with a button to push once the port is available.
