+#Ambari Views Commons Module
+
+Have this as a dependency in the view which need the functionality.
+
+This has common code for:
+
+* HDFS access
+
+**Note: More to be added later**
+
+### How to Include it in dependant project
+
+In the service class for the project use `commons` projects code in the way described in the below example for `files` view.
+
+```java
+package org.apache.ambari.view.filebrowser;
+
+import javax.ws.rs.Path;
+
+import org.apache.ambari.view.ViewContext;
+
+import com.google.inject.Inject;
+import org.apache.ambari.view.commons.hdfs.FileOperationService;
+import org.apache.ambari.view.commons.hdfs.UploadService;
+import org.apache.ambari.view.commons.hdfs.UserService;
+
+/**
+ * Root files service
+ */
+public class FileBrowserService {
+
+  @Inject
+  ViewContext context;
+
+  /**
+   * @see UploadService
+   * @return service
+   */
+  @Path("/upload")
+  public UploadService upload() {
+    return new UploadService(context);
+  }
+
+  /**
+   * @see org.apache.ambari.view.commons.hdfs.FileOperationService
+   * @return service
+   */
+  @Path("/fileops")
+  public FileOperationService fileOps() {
+    return new FileOperationService(context);
+  }
+
+  /**
+   * @see org.apache.ambari.view.commons.hdfs.UserService
+   * @return service
+   */
+  @Path("/user")
+  public UserService userService() { return new UserService(context); }
+
+}
+```
+
+
+####Also, look into the various ember addons that are included in `src/main/resources/ui`.
+Currently we have:
+
+* hdfs-directory-viewer
+
+**More to be added later**

+# Hdfs-directory-viewer
+
+Ember Addon to view the HDFS file system.
+
+Different Ambari views can use this in their view. Common code should be usable in every view.
+
+# How to use it
+
+### Including it in dependant project
+Add the following code in package.json of the dependant view
+
+```javascript
+"name": "files",
+"ember-addon": {
+	"paths": [
+	  "../../../../../commons/src/main/resources/ui/hdfs-directory-viewer"
+	]
+}
+```
+
+`paths` is an array which includes all the addons shares in ```commons``` library. The entries should be the relative path to the addon in this ```commons``` repository.
+
+### Including the UI dependencies in the dependent project
+As we are going to include the component using the `ember-addon` config in `package.json` and not by the `ember install` way, the UI dependencies also has to be included in the dependent projects `bower.json` file if not already added.
+
+```
+"bootstrap": "~3.3.6",
+"bootstrap-treeview": "~1.2.0",
+"font-awesome": "~4.5.0"
+```
+
+### Overriding configs in dependant project
+
+Create a util object in `utils` directory using `ember generate util <object name>` and override it as follows:
+
+```javascript
+import ViewerConfig from 'hdfs-directory-viewer/utils/viewer-config';
+
+export default ViewerConfig.extend({
+  showOnlyDirectories: true,
+
+  expandIcon: 'fa fa-chevron-right',
+  collapseIcon: 'fa fa-chevron-down',
+
+  listDirectoryUrl(pathParams) {
+    return `/api/v1/views/FILES/versions/1.0.0/instances/files/resources/files/fileops/listdir?${pathParams}`;
+  }
+});
+```
+
+All the functions and attributes in `hdfs-directory-viewer/utils/viewer-config` can be overriden
+
+### Passing the object to the view template
+
+```javascript
+import Ember from 'ember';
+import MyViewerConfig from '../utils/my-viewer-config';
+
+export default Ember.Controller.extend({
+  config: MyViewerConfig.create(),
+  actions: {
+    viewerError: function() {
+      console.log("Failed to fetch the content!!!");
+    },
+    viewerSelectedPath: function(data) {
+      console.log(`User selected: path: ${data.path}, isDirectory: ${data.isDirectory}`);
+    }
+  }
+});
+```
+
+```html
+...
+<div class="directory-viewer-wrap">
+  {{directory-viewer
+    config=config
+    errorAction="viewerError"
+    pathSelectAction="viewerSelectedPath"
+  }}
+</div>
+...
+```
