@tiffany-kobiton I revised some contents and add an additional page:

• Add a separate page to include instructions for Java when using Appium AI. This page acts as a reference guide.
• Update the Write effective descriptions in user-guide-appium-ai.adoc to remove actions in natural language descriptions, such as Enter email in the username field or
  Select Calgary from the city dropdown (as they are not supported, the description should only include the element).
