+This method uses a pre-built SD card image with the JetCard software dependencies and configuration already done.  This is likely the easiest option
+if you're new to Jetson.
+
+1. Download the JetCard image for your platform
+
+    | JetPack Version  | Jetson Platform  | Download                    |
+    |------------------|------------------|-----------------------------|
+    | 4.4.1            | Jetson Nano 2GB  | [jetcard_441_nano2gb.sh](#) |
+    | 4.4.1            | Jetson Nano 4GB  | [jetcard_441_nano4gb.sh](#) |
+    | 4.4.1            | Jetson Xavier NX | [jetcard_441_nx.sh](#)   |
 
-2. Insert a 32GB+ SD card into the desktop machine
-3. Using [Etcher](https://www.balena.io/etcher/) select ``jetcard_v0p0p0.img`` and flash it onto the SD card
-4. Remove the SD card from the desktop machine
+    > The old JetCard image may be downloaded here [jetcard_v0p0p0.img](https://drive.google.com/open?id=1wXD1CwtxiH5Mz4uSmIZ76fd78zDQltW_)
 
-You may now insert the SD card into the Jetson Nano, power on, and enjoy the pre-configured system!

-### Option 2 - Create JetCard from scratch
+### Option 2 - Use installation script
 
-1. Flash Jetson Nano following the [Getting Started Guide](https://developer.nvidia.com/embedded/learn/get-started-jetson-nano-devkit)
+This method installs the JetCard software and configuration on an existing SD card image.  This may be the best option if you're already using Jetson,
+or want to customize the installation.
 
-    > For Jetson TX2 / Xavier, use the [JetPack](https://developer.nvidia.com/embedded/jetpack) SDK manager
+1. Setup your Jetson device using the official [Getting Started Guide](https://developer.nvidia.com/embedded/learn/getting-started-jetson) for your platform.
 
-2. On the Jetson, run the JetCard installation script
+2. On your Jetson, open a new terminal ``CTRL+ALT+T``
+3. Clone the JetCard git repository
 
     ```bash
     git clone https://github.com/NVIDIA-AI-IOT/jetcard
+    ```
+4. Navigate into the JetCard directory.  The installation script must be called from this directory.
+
+    ```bash
     cd jetcard
-    ./install.sh <password>
     ```
-
-Once the ``install.sh`` script finishes, your system should be configured identically to the SD card image mentioned above.
+4. Run the interactive installation script, and select the option depending on your needs.  By default, it will install all packages. This enables AI projects like JetBot.
 
+    ```bash
+    sudo ./install.sh
+    ```
+5. Once the installation is finish, enjoy your configured system!
