 1. If this is your first time using a development container, please ensure your system meets the pre-reqs (i.e. have Docker installed) in the [getting started steps](https://aka.ms/vscode-remote/containers/getting-started).
 
 2. To use this repository, you can either open the repository in an isolated Docker volume:
 
-    - Press <kbd>F1</kbd> and select the **Remote-Containers: Try a Sample...** command.
+    - Press <kbd>F1</kbd> and select the **Dev Containers: Try a Sample...** command.
     - Choose the "Java" sample, wait for the container to start, and try things out!
-        > **Note:** Under the hood, this will use the **Remote-Containers: Clone Repository in Container Volume...** command to clone the source code in a Docker volume instead of the local filesystem. [Volumes](https://docs.docker.com/storage/volumes/) are the preferred mechanism for persisting container data.

[Volumes](https://docs.docker.com/storage/volumes/) are the preferred mechanism for persisting container data.
 
    Or open a locally cloned copy of the code:
 
    - Clone this repository to your local filesystem.
-   - Press <kbd>F1</kbd> and select the **Remote-Containers: Open Folder in Container...** command.
+   - Press <kbd>F1</kbd> and select the **Dev Containers: Open Folder in Container...** command.
    - Select the cloned copy of this folder, wait for the container to start, and try things out!
 
 ## Things to try
 
 Once you have this sample opened, you'll be able to work with it like you would locally.
 
-> **Note:** This container runs as a non-root user with sudo access by default. Comment out `"remoteUser": "vscode"` in `.devcontainer/devcontainer.json` if you'd prefer to run as root.
-
 Some things to try:
 
 1. **Edit:**
    - Open `src/main/java/com/mycompany/app/App.java`.
    - Try adding some code and check out the language features.
-   - Notice that the Java extension pack is already installed in the container since the `.devcontainer/devcontainer.json` lists `"vscjava.vscode-java-pack"` as an extension to install automatically when the container is created.
+   - Make a spelling mistake and notice it is detected. The [Code Spell Checker](https://marketplace.visualstudio.com/items?itemName=streetsidesoftware.code-spell-checker) extension was automatically installed because it is referenced in `.devcontainer/devcontainer.json`.
+   - Also notice that the [Extension Pack for Java](https://marketplace.visualstudio.com/items?itemName=vscjava.vscode-java-pack) is installed. The JDK is in the `mcr.microsoft.com/devcontainers/java` image and Dev Container settings and metadata are automatically picked up from [image labels](https://containers.dev/implementors/reference/#labels).
+
 2. **Terminal:** Press <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>\`</kbd> and type `uname` and other Linux commands from the terminal window.
+
 3. **Build, Run, and Debug:**
    - Open `src/main/java/com/mycompany/app/App.java`.
    - Add a breakpoint.
    - Press <kbd>F5</kbd> to launch the app in the container.
    - Once the breakpoint is hit, try hovering over variables, examining locals, and more.
+
 4. **Run a Test:**
    - Open `src/test/java/com/mycompany/app/AppTest.java`.
    - Put a breakpoint in a test.
    - Click the `Debug Test` in the Code Lens above the function and watch it hit the breakpoint.
 
+5. **Install Node.js using a Dev Container Feature:**
+   - Press <kbd>F1</kbd> and select the **Dev Containers: Configure Container Features...** or **Codespaces: Configure Container Features...** command.
+   - Type "node" in the text box at the top.
+   - Check the check box next to "Node.js (via nvm) and yarn" (published by devcontainers) 
+   - Click OK
+   - Press <kbd>F1</kbd> and select the **Dev Containers: Rebuild Container** or **Codespaces: Rebuild Container** command so the modifications are picked up.
