+
+# Viewing instance settings
+
+If the instance is in the [instances list](https://maid.zone/soundcloak/instances.html), then you can view a few of the settings there (ProxyStreams, ProxyImages, Restream)
+
+You can also visit `<instance>/_/info` to view some of the settings. This endpoint is only available if `InstanceInfo` is enabled by the maintainer.
+
+Example output: (from [soundcloak.fly.dev/_/info](https://soundcloak.fly.dev/_/info))

+
+# Preferences
+
+Click the "Preferences" button on the main page, or navigate to `<instance>/_/preferences` to get started.
+
+Instance maintainers can set their own default preferences.
+
+[Refer to here](PREFERENCES.md) for a full list of preferences. If you don't see certain preferences on the page, it means that you have to enable a different preference to configure this one, or this feature has been disabled on the backend.
+
+Those preferences are saved in a cookie.
+
+## Management
+
+Scroll down to the end of the preferences page. There you can see a management tab for preferences. You can export your preferences as a JSON file, import the preferences, or reset them.
+
+# Redirecting from SoundCloud to soundcloak
+
+soundcloak tries to keep the URL schemes same to SoundCloud's, so you can just replace `soundcloud.com` with your instance URL. For short links: `https://on.soundcloud.com/boiKDP46fayYDoVK9` -> `<instance>/on/boiKDP46fayYDoVK9`
