-
-🌀 `Portal` is a framework for rapidly building rich data portal frontends using a modern frontend approach (javascript, React, SSR).
-
-`Portal` assumes a "decoupled" approach where the frontend is a separate service from the backend and interacts with backend(s) via an API. It can be used with any backend and has out of the box support for [CKAN][]. `portal` is built in Javascript and React on top of the popular [Next.js][] framework.

-## Getting Started
-
-### Setup
-
-Install a recent version of Node. You'll need Node 10.13 or later.
-
-### Create a Portal app
-
-To create a Portal app, open your terminal, cd into the directory you'd like to create the app in, and run the following command:
-
-```console
-npm init portal-app my-data-portal
-```
-
-> NB: Under the hood, this uses the tool called create-next-app, which bootstraps a Next.js app for you. It uses this template through the --example flag.

-> If it doesn’t work, please open an issue.
+**🚩 UPDATE April 2023: This example is now deprecated - though still works!. Please use the [new CKAN examples](https://github.com/datopian/portaljs/tree/main/examples)**
