 ### WebNN Installation Guides
 
-WebNN requires a compatible browser to run, and Windows 11 v21H2 (DML 1.6.0) or higher for GPU. Try the latest Google Chrome* Canary or Microsoft Edge Canary, which requires enabling WebNN functionality in the settings.
+To get started with WebNN on Intel AI PCs you will need:
+* Window 11, version 21H2 or newer
+* It's recommended to install the latest [Intel® Arc™ & Iris® Xe Graphics](https://www.intel.com/content/www/us/en/download/785597/intel-arc-iris-xe-graphics-windows.html) on Windows for improved WebNN compatibility and performance
 
-1. Download the latest [Google Chrome Canary](https://www.google.com/chrome/canary/) or [Microsoft Edge Canary](https://www.microsoft.com/en-us/edge/download/insider) browser. 
-2. To enable WebNN, in your browser address bar, `enter chrome://flags`, and then press `Enter`. An Experiments page opens. 
-3. In the Search flags box, enter `webnn`. `Enables WebNN API` appears. 
-4. In the drop-down menu, select `Enabled`. 
-5. Relaunch your browser.
+1. Download and install the latest [Chrome Canary](https://www.google.com/chrome/canary/) or [Edge Canary](https://www.microsoft.com/en-us/edge/download/insider?form=MA13FJ)
+2. Navigate to `about://flags` in browser address bar
+3. Search for `Enables WebNN API` and change it to "Enabled"
+4. Exit browser
+
+#### Running WebNN on CPU or GPU
+1. Launch Chrome Canary or Edge Canary
 
 #### Running WebNN on NPU
 At present, the [image classification](https://webmachinelearning.github.io/webnn-samples/image_classification/) and [object detection](https://webmachinelearning.github.io/webnn-samples/object_detection/) samples support NPU.
 
-* Install NPU driver:
-
-  For Intel® AI Boost NPU of Intel® Core™ Ultra processors, download and install the [latest Intel NPU driver](https://www.intel.com/content/www/us/en/download/794734/intel-npu-driver-windows.html).
-
-* Google Chrome Canary:
-1. Download the latest redistributable [Microsoft.AI.DirectML](https://www.nuget.org/packages/Microsoft.AI.DirectML/).
-2. Extract the package and copy the DirectML.dll (e.g. \bin\x64-win\DirectML.dll) to the Chrome Canary’s directory (e.g.C:\Users\"username"\AppData\Local\Google\Chrome SxS\Application\"version number"). Note that Chrome Canary may automatically update to a new version, in which case DirectML.dll will need to be recopied to the directory.
-3. Launch your browser in Windows Command Line:
-```bash
-"%LOCALAPPDATA%\Google\Chrome SxS\Application\chrome.exe" --use-redist-dml --disable_webnn_for_npu=0
-```
-
-* Microsoft Edge Canary:
-1. Launch your browser in Windows Command Line:
-```bash
-"%LOCALAPPDATA%\Microsoft\Edge SxS\Application\msedge.exe" --disable_webnn_for_npu=0
-```
-2. For the first time you enable the `Enables WebNN API` flag, please wait a moment while the latest redistributable [Microsoft.AI.DirectML](https://www.nuget.org/packages/Microsoft.AI.DirectML/) is downloaded automatically before trying the samples.
+* Window 11, version 24H2 or newer
+* It's recommended to install the latest [Intel® Core™ Ultra NPU Driver on Windows](https://www.intel.com/content/www/us/en/download/794734/intel-npu-driver-windows.html) for improved WebNN compatibility and performance
+* **Google Chrome Canary:**
+  1. Download the latest redistributable [Microsoft.AI.DirectML](https://www.nuget.org/packages/Microsoft.AI.DirectML/1.15.2), rename the "microsoft.ai.directml.\<version>.nupkg" to "microsoft.ai.directml.\<version>.nupkg.zip" and extract it
+  2. Copy `\bin\x64-win\DirectML.dll` to `%LOCALAPPDATA%\Google\Chrome SxS\Application\<version>\`
+      - `%LOCALAPPDATA%` means `C:\Users\<username>\AppData\Local\`
+      - Note that Chrome Canary frequently updates automatically. When this occurs, you'll need to recopy the DirectML.dll to the new version's directory
+  3. Launch Chrome Canary in Windows Command Line:
+  ```bash
+  "%LOCALAPPDATA%\Google\Chrome SxS\Application\chrome.exe" --use-redist-dml --disable_webnn_for_npu=0
+  ```
+
+* **Microsoft Edge Canary:**
+  1. Ensure the DirectML.dll was downloaded automatically (may take several minutes):
+      - Launch Edge Canary
+      - Go to `%LOCALAPPDATA%\Microsoft\Edge SxS\User Data`, check the `EdgeOnnxRuntimeDirectML\<version>\DirectML.dll` exists
+      - `%LOCALAPPDATA%` means `C:\Users\<username>\AppData\Local\`
+      - Exit Edge Canary
+  2. Launch Edge Canary in Windows Command Line:
+  ```bash
+  "%LOCALAPPDATA%\Microsoft\Edge SxS\Application\msedge.exe" --disable_webnn_for_npu=0
+  ```
 
 * Notes:
 1. There is an intermittent issue with the Intel NPU driver that causes failure of NPU adapter creation. The `WebNN(NPU)` backend button in the samples will be disabled with message "Unable to find a capable adapter". If you encounter this issue, please relaunch your browser and try again.
