-# REST API Usage
+# REST API & FreqUI
+
+## FreqUI
+
+Freqtrade provides a builtin webserver, which can serve [FreqUI](https://github.com/freqtrade/frequi), the freqtrade UI.
+
+By default, the UI is not included in the installation (except for docker images), and must be installed explicitly with `freqtrade install-ui`.
+This same command can also be used to update freqUI, should there be a new release.
+
+Once the bot is started in trade / dry-run mode (with `freqtrade trade`) - the UI will be available under the configured port below (usually `http://127.0.0.1:8080`).
+
+!!! info "Alpha release"
+    FreqUI is still considered an alpha release - if you encounter bugs or inconsistencies please open a [FreqUI issue](https://github.com/freqtrade/frequi/issues/new/choose).
+
+!!! Note "developers"
+    Developers should not use this method, but instead use the method described in the [freqUI repository](https://github.com/freqtrade/frequi) to get the source-code of freqUI.

 Also, the standard disallows `*` CORS policies for requests with credentials, so this setting must be set appropriately.
