 ## Configuration
 
+### Version 1.x.x vs. Version 2.x.x
+
+In version 2.0.0 the PV Info build tool was changed from [Create React App](https://github.com/facebook/create-react-app) to [Vite](https://github.com/vitejs/vite). Create React App has been deprecated by Facebook and is no longer maintained. This can cause some issues with security vulnerabilities and isn't good for the long term so we have switched to Vite. Vite is mostly a drop-in replacement but see here for differences in PV Info 1.x.x and 2.x.x - [Version 2 notes](docs/v2-migration.md).
+
+It is important to delete the node_modules directory and do an `npm install` to regenerate all the dependencies when converting an existing application to version 2.0.0.
