 ## Install
 
-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
-cd ~/.k8slens/extensions
-ln -s <lens-extension-samples directory>/helloworld-sample helloworld-sample
+git clone https://github.com/lensapp/lens-extension-samples.git
+ln -s $(pwd)/lens-extension-samples/helloworld-sample ~/.k8slens/extensions/helloworld-sample
 ```
 
 ## Build
 
 To build the extension you can use `make` or run the `npm` commands manually:
 
 ```sh
-cd <lens-extension-samples directory>/helloworld-sample
+cd lens-extension-samples/helloworld-sample
 make build
 ```
 
 OR
 
 ```sh
-cd <lens-extension-samples directory>/helloworld-sample
+cd lens-extension-samples/helloworld-sample
 npm install
 npm run build
 ```
 
 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
+cd lens-extension-samples/helloworld-sample
 npm run dev
 ```
