-## Overview
+# Webui-vue
+
+The [webui-vue](https://github.com/openbmc/webui-vue) repository
+will replace phosphor-webui once it is deprecated. Webui-vue uses the
+[Vue.js](https://vuejs.org/) framework to interact with the BMC via the
+Redfish API.

+replacing the Angular.JS application.

+## Load Web UI against QEMU
+
+Connect to Web UI in QEMU
+
+1. You will need the QEMU session running per instructions in the
+   "Download and Start QEMU Session" section of
+   [dev-environment](https://github.com/openbmc/docs/blob/master/development/dev-environment.md).
+
+2. Assuming you used the default of 2443 for the HTTPS port in your QEMU
+   session, you will point your web browser to https://localhost:2443.
+
+3. Login with default username and password and verify basic Web UI features are
+   working as expected.
+
+**Note** You will need to approve the security exception in your browser to
+connect. OpenBMC is running with a self-signed SSL certificate.

+provides a web-based interface for an OpenBMC. It uses the
+[AngularJS](https://angularjs.org/) framework to interact with the BMC via REST API calls. It allows users
 to view hardware information, update firmware, set network settings, and much
 more.
 
-A common use case for changes to the web UI is to put some system specific
-branding into it. This lesson will focus on how to do that.

-## Load web UI against QEMU
+Phosphor-webui was built on AngularJS and AngularJS goes End of Life June 30,
+2021.
 
-1. Connect to web UI in QEMU
-
-  You will need the QEMU session running per instructions in section
-  "Download and Start QEMU Session" of [dev-environment](https://github.com/openbmc/docs/blob/master/development/dev-environment.md)

-  Login with default userid and password and verify basic web UI features are
-  working as expected.
-
-  **Note** You will need to approve the security exception in your browser to
-  connect. OpenBMC is running with a self-signed SSL certificate. Accepting
-  this is key for the next steps.

-## Customize web UI code
+## Customize Phosphor-webui
 
 1. Clone the repository
 
-  ```
-  git clone https://github.com/openbmc/phosphor-webui.git
-  ```
+   ```
+   git clone https://github.com/openbmc/phosphor-webui.git
+   ```
 
 2. Install appropriate packages and start web UI
 
-  Follow the directions in the phosphor-webui [README](https://github.com/openbmc/phosphor-webui/blob/master/README.md)
-  to install the required packages and start the web UI. You can use the
-  development environment created in [dev-environment](https://github.com/openbmc/docs/blob/master/development/dev-environment.md)
-  or your own system assuming you install the required packages noted in the
-  README.

 3. Customize the web UI login screen and verify
 
-  Kill your npm run from the previous step using Ctrl^C. Grab a png that you
-  will use to represent your customized version of OpenBMC.  Feel free to use
-  any .png you wish for this step.
-  ```
-  wget http://www.pngmart.com/files/3/Free-PNG-Transparent-Image.png
-  ```
+   Kill your npm run from the previous step using Ctrl^C. Grab a png that you
+   will use to represent your customized version of OpenBMC. Feel free to use
+   any .png you wish for this step.
 
-  Copy your new .png into the appropriate directory
-  ```
-  cp Free-PNG-Transparent-Image.png app/assets/images/
-  ```
+   ```
+   wget http://www.pngmart.com/files/3/Free-PNG-Transparent-Image.png
+   ```
 
-  Point to that new image in the web UI HTML
-  ```
-  vi app/login/controllers/login-controller.html
-  # Replace the logo.svg near the top with Free-PNG-Transparent-Image.png
-  <img src="../../assets/images/Free-PNG-Transparent-Image.png" class="login__logo" alt="OpenBMC logo" role="img"/>
-  ```
+   Copy your new .png into the appropriate directory
 
-  Start up the server with your change
-  ```
-  npm run-script server
-  ```
+   ```
+   cp Free-PNG-Transparent-Image.png app/assets/images/
+   ```
 
-  Load web browser at https://localhost:8080 and verify your new image is on
-  the login screen.
+   Point to that new image in the web UI HTML
 
-  Kill your npm run using Ctrl^C.
+   ```
+   vi app/login/controllers/login-controller.html
+   # Replace the logo.svg near the top with Free-PNG-Transparent-Image.png
+   <img src="../../assets/images/Free-PNG-Transparent-Image.png" class="login__logo" alt="OpenBMC logo" role="img"/>
+   ```
+
+   Start up the server with your change
+
+   ```
+   npm run-script server
+   ```
+
+   Load web browser at https://localhost:8080 and verify your new image is on
+   the login screen.
+
+   Kill your npm run using Ctrl^C.
 
 4. Customize the header with the new image and verify
+   The header is on every page in the web UI. It has a smaller version of the
+   logo in it which we are changing with this step.
 
-  The header is on every page in the web UI. It has a smaller version of the
-  logo in it which we are changing with this step.
+   Similar to the previous step, modify the appropriate HTML for the header:
 
-  Similar to the previous step, modify the appropriate HTML for the header:
-  ```
-  vi app/common/directives/app-header.html
-  # Replace logo.svg with Free-PNG-Transparent-Image.png again
-  <div class="logo__wrapper"><img src="../../assets/images/Free-PNG-Transparent-Image.png" class="header__logo" alt="company logo"/></div>
-  ```
+   ```
+   vi app/common/directives/app-header.html
+   # Replace logo.svg with Free-PNG-Transparent-Image.png again
+   <div class="logo__wrapper"><img src="../../assets/images/Free-PNG-Transparent-Image.png" class="header__logo" alt="company logo"/></div>
+   ```
 
-  Start up the server with your change
-  ```
-  npm run-script server
-  ```
-  Browse to https://localhost:8080 and verify your new image is on the header.
-  Note that you will need to log in to view the header. Point the web UI to your
-  QEMU session by typing the QEMU session (e.g. localhost:2443) in the "BMC HOST
-  OR BMC IP ADDRESS" field.
+   Start up the server with your change
 
-Note that in the HTML where you're replacing the images, there is also the
-corresponding text that goes with the images. Changing the text to match
-with your logo is also something you can easily do to customize your creation
-of an OpenBMC system.
+   ```
+   npm run-script server
+   ```
 
-And that's it! You've downloaded, customized, and run the OpenBMC phosphor-webui
-code!
+   Browse to https://localhost:8080 and verify your new image is on the header.
