+# FolderExplorer control
+
+This control allows you to explore a folder structure by clinking on a folder to load it's sub-folders and using a breadcrumb navigation to navigate back to a previous level.
+It also allows the user to create a new folder at the current level being explored.
+
+Here is an example of the control:
+
+![FolderExplorer](../assets/FolderExplorer.png)
+
+`FolderExplorer` folder creation:
+
+![FolderExplorer add folder](../assets/FolderExplorer-new.png)
+
+## How to use this control in your solutions
+
+- Check that you installed the `@pnp/spfx-controls-react` dependency. Check out the [getting started](../../#getting-started) page for more information about installing the dependency.
+- Import the control into your component:
+
+```TypeScript
+import { FolderExplorer, IFolder } from "@pnp/spfx-controls-react/lib/FolderExplorer";
+```
+
+- Use the `FolderExplorer` control in your code as follows:
+
+```TypeScript
+<FolderExplorer
+              context={this.props.context}
+              rootFolder={{
+                Name: 'Documents',
+                ServerRelativeUrl: `/sites/TestSite/Shared Documents`
+              }}
+              defaultFolder={{
+                Name: 'Documents',
+                ServerRelativeUrl: `/sites/TestSite/Shared Documents`
+              }}
+              onSelect={this._onFolderSelect}
+              canCreateFolders={true}
+            />
+```
+
+- The `onSelect` change event returns the selected folder and can be implemented as follows:
+
+```TypeScript
+private _onFolderSelect = (folder: IFolder): void => {
+  console.log('selected folder', folder);
+}
+```
+
+## Implementation
+
+The `FolderExplorer` control can be configured with the following properties:
+
+| Property | Type | Required | Description |
+| ---- | ---- | ---- | ---- |
+| context | WebPartContext \| ExtensionContext | yes | The context object of the SPFx loaded webpart or customizer. |
+| rootFolder | IFolder | yes | The lowest level folder that can be explored. This can be the root folder of a library. |
+| defaultFolder | IFolder | yes | The default folder to be explored. |
+| canCreateFolders | boolean | no | Allow current user to create folders on the target location. If enabled, you need to ensure that the user has the required permissions. |
+| hiddenBreadcrumb | boolean | no | Hide the breadcrumb control. |
+| hiddenFilterBox | boolean | no | Hide the filter box |
+| onSelect | (folder: IFolder): void | no | Callback function called after a folder is selected. |
