+## Properties
+
+|  Property | Type | Description |
+|  --- | --- | --- |
+|  [get](./kibana-plugin-core-public.iuisettingsclient.get.md) | <code>&lt;T = any&gt;(key: string, defaultOverride?: T) =&gt; T</code> | Gets the value for a specific uiSetting. If this setting has no user-defined value then the <code>defaultOverride</code> parameter is returned (and parsed if setting is of type "json" or "number). If the parameter is not defined and the key is not registered by any plugin then an error is thrown, otherwise reads the default value defined by a plugin. |
+|  [get$](./kibana-plugin-core-public.iuisettingsclient.get_.md) | <code>&lt;T = any&gt;(key: string, defaultOverride?: T) =&gt; Observable&lt;T&gt;</code> | Gets an observable of the current value for a config key, and all updates to that config key in the future. Providing a <code>defaultOverride</code> argument behaves the same as it does in \#get() |
+|  [getAll](./kibana-plugin-core-public.iuisettingsclient.getall.md) | <code>() =&gt; Readonly&lt;Record&lt;string, PublicUiSettingsParams &amp; UserProvidedValues&gt;&gt;</code> | Gets the metadata about all uiSettings, including the type, default value, and user value for each key. |
+|  [getSaved$](./kibana-plugin-core-public.iuisettingsclient.getsaved_.md) | <code>&lt;T = any&gt;() =&gt; Observable&lt;{</code><br/><code>        key: string;</code><br/><code>        newValue: T;</code><br/><code>        oldValue: T;</code><br/><code>    }&gt;</code> | Returns an Observable that notifies subscribers of each update to the uiSettings, including the key, newValue, and oldValue of the setting that changed. |
+|  [getUpdate$](./kibana-plugin-core-public.iuisettingsclient.getupdate_.md) | <code>&lt;T = any&gt;() =&gt; Observable&lt;{</code><br/><code>        key: string;</code><br/><code>        newValue: T;</code><br/><code>        oldValue: T;</code><br/><code>    }&gt;</code> | Returns an Observable that notifies subscribers of each update to the uiSettings, including the key, newValue, and oldValue of the setting that changed. |
+|  [getUpdateErrors$](./kibana-plugin-core-public.iuisettingsclient.getupdateerrors_.md) | <code>() =&gt; Observable&lt;Error&gt;</code> | Returns an Observable that notifies subscribers of each error while trying to update the settings, containing the actual Error class. |
+|  [isCustom](./kibana-plugin-core-public.iuisettingsclient.iscustom.md) | <code>(key: string) =&gt; boolean</code> | Returns true if the setting wasn't registered by any plugin, but was either added directly via <code>set()</code>, or is an unknown setting found in the uiSettings saved object |
+|  [isDeclared](./kibana-plugin-core-public.iuisettingsclient.isdeclared.md) | <code>(key: string) =&gt; boolean</code> | Returns true if the key is a "known" uiSetting, meaning it is either registered by any plugin or was previously added as a custom setting via the <code>set()</code> method. |
+|  [isDefault](./kibana-plugin-core-public.iuisettingsclient.isdefault.md) | <code>(key: string) =&gt; boolean</code> | Returns true if the setting has no user-defined value or is unknown |
+|  [isOverridden](./kibana-plugin-core-public.iuisettingsclient.isoverridden.md) | <code>(key: string) =&gt; boolean</code> | Shows whether the uiSettings value set by the user. |
+|  [overrideLocalDefault](./kibana-plugin-core-public.iuisettingsclient.overridelocaldefault.md) | <code>(key: string, newDefault: any) =&gt; void</code> | Overrides the default value for a setting in this specific browser tab. If the page is reloaded the default override is lost. |
+|  [remove](./kibana-plugin-core-public.iuisettingsclient.remove.md) | <code>(key: string) =&gt; Promise&lt;boolean&gt;</code> | Removes the user-defined value for a setting, causing it to revert to the default. This method behaves the same as calling <code>set(key, null)</code>, including the synchronization, custom setting, and error behavior of that method. |
+|  [set](./kibana-plugin-core-public.iuisettingsclient.set.md) | <code>(key: string, value: any) =&gt; Promise&lt;boolean&gt;</code> | Sets the value for a uiSetting. If the setting is not registered by any plugin it will be stored as a custom setting. The new value will be synchronously available via the <code>get()</code> method and sent to the server in the background. If the request to the server fails then a updateErrors$ will be notified and the setting will be reverted to its value before <code>set()</code> was called. |

+## kibana-plugin-core-public package
+
+The Kibana Core APIs for client-side plugins.
+
+A plugin's `public/index` file must contain a named import, `plugin`<!-- -->, that implements [PluginInitializer](./kibana-plugin-core-public.plugininitializer.md) which returns an object that implements [Plugin](./kibana-plugin-core-public.plugin.md)<!-- -->.
+
+The plugin integrates with the core system via lifecycle events: `setup`<!-- -->, `start`<!-- -->, and `stop`<!-- -->. In each lifecycle method, the plugin will receive the corresponding core services available (either [CoreSetup](./kibana-plugin-core-public.coresetup.md) or [CoreStart](./kibana-plugin-core-public.corestart.md)<!-- -->) and any interfaces returned by dependency plugins' lifecycle method. Anything returned by the plugin's lifecycle method will be exposed to downstream dependencies when their corresponding lifecycle methods are invoked.

Behaves similarly to the <code>basename</code> option except that this wrapper hides any history stack entries from outside the scope of this base path.<!-- -->This wrapper also allows Core and Plugins to share a single underlying global <code>History</code> instance without exposing the history of other applications.<!-- -->The [createSubHistory](./kibana-plugin-core-public.scopedhistory.createsubhistory.md) method is particularly useful for applications that contain any number of "sub-apps" which should not have access to the main application's history or basePath. |
+|  [SimpleSavedObject](./kibana-plugin-core-public.simplesavedobject.md) | This class is a very simple wrapper for SavedObjects loaded from the server with the [SavedObjectsClient](./kibana-plugin-core-public.savedobjectsclient.md)<!-- -->.<!-- -->It provides basic functionality for creating/saving/deleting saved objects, but doesn't include any type-specific implementations. |

+## kibana-plugin-core-server package
+
+The Kibana Core APIs for server-side plugins.
+
+A plugin requires a `kibana.json` file at it's root directory that follows [the manfiest schema](./kibana-plugin-core-server.pluginmanifest.md) to define static plugin information required to load the plugin.
+
+A plugin's `server/index` file must contain a named import, `plugin`<!-- -->, that implements [PluginInitializer](./kibana-plugin-core-server.plugininitializer.md) which returns an object that implements [Plugin](./kibana-plugin-core-server.plugin.md)<!-- -->.
+
+The plugin integrates with the core system via lifecycle events: `setup`<!-- -->, `start`<!-- -->, and `stop`<!-- -->. In each lifecycle method, the plugin will receive the corresponding core services available (either [CoreSetup](./kibana-plugin-core-server.coresetup.md) or [CoreStart](./kibana-plugin-core-server.corestart.md)<!-- -->) and any interfaces returned by dependency plugins' lifecycle method. Anything returned by the plugin's lifecycle method will be exposed to downstream dependencies when their corresponding lifecycle methods are invoked.
+
+## Classes
+
+|  Class | Description |
+|  --- | --- |
+|  [BasePath](./kibana-plugin-core-server.basepath.md) | Access or manipulate the Kibana base path |
+|  [ClusterClient](./kibana-plugin-core-server.clusterclient.md) | Represents an Elasticsearch cluster API client created by the platform. It allows to call API on behalf of the internal Kibana user and the actual user that is derived from the request headers (via <code>asScoped(...)</code>).<!-- -->See [ClusterClient](./kibana-plugin-core-server.clusterclient.md)<!-- -->. |
+|  [CspConfig](./kibana-plugin-core-server.cspconfig.md) | CSP configuration for use in Kibana. |
+|  [ElasticsearchConfig](./kibana-plugin-core-server.elasticsearchconfig.md) | Wrapper of config schema. |
+|  [ElasticsearchErrorHelpers](./kibana-plugin-core-server.elasticsearcherrorhelpers.md) | Helpers for working with errors returned from the Elasticsearch service.Since the internal data of errors are subject to change, consumers of the Elasticsearch service should always use these helpers to classify errors instead of checking error internals such as <code>body.error.header[WWW-Authenticate]</code> |
+|  [KibanaRequest](./kibana-plugin-core-server.kibanarequest.md) | Kibana specific abstraction for an incoming request. |
+|  [RouteValidationError](./kibana-plugin-core-server.routevalidationerror.md) | Error to return when the validation is not successful. |
+|  [SavedObjectsClient](./kibana-plugin-core-server.savedobjectsclient.md) |  |
+|  [SavedObjectsErrorHelpers](./kibana-plugin-core-server.savedobjectserrorhelpers.md) |  |
+|  [SavedObjectsRepository](./kibana-plugin-core-server.savedobjectsrepository.md) |  |
+|  [SavedObjectsSerializer](./kibana-plugin-core-server.savedobjectsserializer.md) | A serializer that can be used to manually convert [raw](./kibana-plugin-core-server.savedobjectsrawdoc.md) or [sanitized](./kibana-plugin-core-server.savedobjectsanitizeddoc.md) documents to the other kind. |
+|  [SavedObjectTypeRegistry](./kibana-plugin-core-server.savedobjecttyperegistry.md) | Registry holding information about all the registered [saved object types](./kibana-plugin-core-server.savedobjectstype.md)<!-- -->. |
+|  [ScopedClusterClient](./kibana-plugin-core-server.scopedclusterclient.md) | Serves the same purpose as "normal" <code>ClusterClient</code> but exposes additional <code>callAsCurrentUser</code> method that doesn't use credentials of the Kibana internal user (as <code>callAsInternalUser</code> does) to request Elasticsearch API, but rather passes HTTP headers extracted from the current user request to the API.<!-- -->See [ScopedClusterClient](./kibana-plugin-core-server.scopedclusterclient.md)<!-- -->. |
