+### Cluster Status
+
+This section provides cluster details including the detected distribution, kernel version, API endpoint and online status.
 
 ## General
 
+General information for the cluster with some settings that can be customized.
+
 ### Cluster Name
 
+The cluster name is inheritated from the kubeconfig by default. You can change the cluster name to another value by updating here. Note this does not update your kubeconfig file.
 
 ### Workspace
 
+This is the Lens Workspace that the cluster is associated with. You can change to another workspace or create a new workspace - this option will take you the Workspaces editor where you can create a new workspace and then 
+navigate back to the cluster settings.
+
 ### Cluster Icon
 
+A random cluster icon is associated with your cluster when it is first created. You can define your own cluster icon here.
+
 ### HTTP Proxy
 
+If you need to use a HTTP proxy to communicate with the Kubernetes API you can define it here.
 
 ### Prometheus
 
+Lens can be configured to query a Prometheus server that is installed in the cluster. The query format used can be configured here to either auto-detect or a pre-configured query format. The available formats are:
+
+* Lens
+* Helm Operator
+* Prometheus Operator
+* Stacklight
+
+For more details of custom Prometheus configurations refer to this [guide](https://github.com/lensapp/lens/blob/master/troubleshooting/custom-prometheus.md).
 
 ### Working Directory
 
+The terminat working directory can be configured here - by default it is set to `$HOME`.
 
 ## Features
 
+Additional Lens features that can be installed by the user.
 
 ### Metrics
 
+Enable timeseries data visualization (Prometheus stack) for your cluster. Install this only if you don't have existing Prometheus stack installed.
 
 ### User Mode
+
+User Mode feature enables non-admin users to see namespaces they have access to. This is achieved by configuring RBAC rules so that every authenticated user is granted to list namespaces.
+
+## Removal
+
+Remove the current cluster.

 ## Installing and Building the extension
 
-Simple Lens extension that adds "hello-world" page to a cluster menu.
+Simple Lens extension that adds "Hello World" page to a cluster menu.
 
 ### Linux
 
+First you will need to clone the [Lens Extension samples](https://github.com/lensapp/lens-extension-samples) repository to your local machine:
+
+```sh
+git clone https://github.com/lensapp/lens-extension-samples.git 
+```
+
+Next you need to create a symlink from the directory that Lens will monitor for user installed extensions to the sample extension, in this case **helloworld-sample**:
+
 ```sh
 mkdir -p ~/.k8slens/extensions
-git clone https://github.com/lensapp/lens-extension-samples.git
-cp -pr lens-extension-samples/helloworld-sample ~/.k8slens/extensions
+cd ~/.k8slens/extensions
+ln -s <lens-extension-samples directory>/helloworld-sample helloworld-sample
 ```
 
 To build the extension you can use `make` or run the `npm` commands manually:
 
 ```sh
-cd ~/.k8slens/extensions/helloworld-sample
+cd <lens-extension-samples directory>/helloworld-sample
 make build
 ```
 
 OR
 
 ```sh
-cd ~/.k8slens/extensions/helloworld-sample
+cd <lens-extension-samples directory>/helloworld-sample
 npm install
 npm run build
 ```
 
-Open Lens application and navigate to a cluster. You should see "Hello World" in the Lens sidebar menu.
+If you want to watch for any source code changes and automatically rebuild the extension you can use:
+
+```sh
+cd <lens-extension-samples directory>/helloworld-sample
+npm run dev
+```
+
+Finally, if you already have Lens open you will need to quit and restart Lens for the extension to be loaded. After this initial restart you can reload Lens and it will pick up any new builds of the extension. Within Lens connect to an existing cluster or [create a new one](../../clusters/adding-clusters.md). You should see then see the "Hello World" page in the Lens sidebar cluster menu.
 
 ## Developing the extension
 
-Let's make a change to the message:
+Let's make a change to the message that our helloworld-sample extension displays:
 
-* Change the message from Hello World from HelloWorld! to **Hello Lens Extensions** in `page.tsx`
-* Rebuild the extension
-* Reload the Lens window
+* Navigate to `<lens-extension-samples directory>/helloworld-sample`.
+* Change the message from HelloWorld! to **Hello Lens Extensions** in `page.tsx`.
+* Rebuild the extension or, if you used `npm run dev`, the extension should automatically rebuild.
+* Reload the Lens window and click on the Hello World page.
 * You should see the updated message showing up.
