 # Overview
 
-A theme is a suite of static resources of images, fonts and color palettes you can use to customize the look and feel of your chat application. The AI DIAL Chat Themes project is an HTTP server hosting themes for the AI DIAL Chat web application. By having a dedicated server for themes, it enables developers and designers to work concurrently and implement changes to themes without needing to redeploy the AI DIAL Chat application.
+A theme is a collection of static resources including images, fonts, and color palettes that you can utilize to personalize the appearance of your [AI DIAL Chat](https://github.com/epam/ai-dial-chat) application. These resources can be stored anywhere and accessed by the chat application via the internet. We provide the AI DIAL Chat Themes service as a convenient method for hosting these static resources and making them accessible for the chat application. However, you have the flexibility to choose your own method for accomplishing this. 
 
-> Refer to [AI DIAL Chat](https://github.com/epam/ai-dial-chat) to learn more about it.
+This approach, having static resources externally, enables developers and designers to work concurrently and implement changes to themes without needing to redeploy the AI DIAL Chat application.
 
-When a theme is configured, chat application users can select it in [user settings](https://github.com/epam/ai-dial/blob/main/docs/user-guide.md#user-settings).

 # Helm Deployment and Configuration
 
-1. You can deploy AI DIAL Chat Themes as a part of a [common dial Helm chart](https://github.com/epam/ai-dial-helm/tree/main/charts/dial) or in a [stand-alone chart](https://github.com/epam/ai-dial-helm/tree/main/charts/dial-extension).

-2. Further, it is necessary to configure AI DIAL Chat to work with AI DIAL Chat Themes. To do that, add `THEMES_CONFIG_HOST` to the chat configuration - refer to [documentation](https://github.com/epam/ai-dial-chat/blob/development/apps/chat/README.md) for details. `THEMES_CONFIG_HOST` environment variable contains the URL to your nginx server with the configuration and images. This ensures that the application fetches your configuration file during loading. If the environment variable is not provided, [default themes and model icons]((./static/config.json)) will be applied.
