 [![Docker Stars](https://img.shields.io/docker/stars/mrcolorrain/vnc-browser?style=flat-square)](https://hub.docker.com/r/mrcolorrain/vnc-browser)
 
 ## Info :information_source:
-VNC-Browser is a minimal, customizable, Linux-based Docker image designed to provide a lightweight environment for browsing the web via VNC.
-This Docker image encapsulates a lightweight, VNC-accessible web browsing environment built on top of Debian and Alpine Linux. It packages a VNC server, noVNC for browser-based VNC access, and the Chromium and Firefox web browsers, providing a compact solution for remotely browsing the web. Whether you're looking to browse securely or need a browsing environment within a containerized setup, VNC-Browser has you covered.
+RDP-Chromium is a minimal, secure, Linux-based Docker image designed to provide a hardened environment for browsing the web via RDP.
+This Docker image encapsulates a secure, RDP-accessible web browsing environment built on Debian Slim. It provides a Chromium web browser in a controlled environment with no shell access, making it ideal for secure browsing scenarios where terminal access must be completely eliminated.
 
 **Key Features ✨**
 
-- **VNC-Ready**: Ready for use with any VNC client or through a web browser using noVNC, offering a user-friendly interface.
-- **Lightweight**: Built on Alpine Linux and Debian Slim, ensuring minimal resource usage.
-- **Customizable**: Set VNC password, initial website URL, auto-start settings for the browser and xterm via environment variables.
-- **Accessible**: Access the VNC server directly or through a browser using noVNC.
+- **RDP-Ready**: Accessible via any RDP client with secure authentication
+- **Lightweight**: Built on Debian Slim, ensuring minimal resource usage
+- **Secure**: No terminal access - shell capabilities completely removed
+- **Browser-Focused**: Optimized specifically for web browsing without system access
