 # @arcgis/core
 
-A minified, unbuilt version of the [ArcGIS API for JavaScript](https://developers.arcgis.com/javascript/) ES modules.
+A minified, unbuilt version of the [ArcGIS Maps SDK for JavaScript](https://developers.arcgis.com/javascript/) ES modules.
 
 ## Features
 
-You can install these modules via [npm](https://npmjs.org/) and then use them directly in a framework such as [React](https://reactjs.org/), [Vue.js](https://vuejs.org) or [Angular](https://cli.angular.io/). Or, you can also create your own custom builds with [Webpack](https://webpackjs.org) or [rollup.js](https://rollupjs.org/guide/en/).
+For an overview of the SDK, visit the [developer documentation](https://developers.arcgis.com/javascript/latest/key-features/) site.

 ## Configure CSS
 
-Set the CSS to the same version as the installed API modules. You can verify the installed API version by running `npm list @arcgis/core`.  If you are working with local assets skip to the *Manage assets locally* section.

 ## Working with assets
 
-For most local builds, the API's assets are automatically pulled from a CDN at runtime and there is no need for additional configuration. The assets include styles, images, web workers, wasm and localization files. Production versions of the API use the ArcGIS CDN, and `next` builds (e.g. `4.19.0-next.20210324`) use jsDelivr, similar to the CSS example above. 
+The default configuration for local builds is for the SDK to automatically pull assets from a CDN at runtime, there is no need for additional configuration. The assets include styles, images, web workers, wasm and localization files. Production versions of the SDK's assets are hosted on the ArcGIS CDN, and `next` builds (e.g. `4.25.0-next.20220921`) use assets hosted on the jsDelivr CDN.
 
 ### Manage assets locally
 
 If you need to manage the assets locally, copy them into your project from `/node_modules/@arcgis/core/assets`, and then set `config.assetsPath` to insure requests for assets are resolved correctly. A simple way to accomplish this is to configure an npm script that runs during your build process. For example, use npm to install `ncp` and configure a script in package.json to copy the folder. 
 
+**Important:** Every time you upgrade the SDK, be sure to recopy the new version of the assets to your project. This ensures the assets stay synchronized.
