+## Design Notes
+
+Portal.js is a React and NextJS based framework for building dataset/resources pages and catalogs. It consists of:
+
+* React components for data portal functionality e.g. data tables, graphs, dataset pages etc
+* Tooling to load data (based on Frictionless)
+* Template sites you can reuse using `create-next-app`
+  * Single dataset micro-site
+  * Github backed catalog
+  * CKAN backed catalog
+  * ...
+* Local development environment
+* Deployment integration with DataHub.io
+
+In summary, technically PortalJS is: NextJS + data specific react components + data loading glue (mostly using frictionless-js).
