+# Docker Hub Repository Overview
+
+**Repository Name:**
+[Your Docker Hub Repository Name]
+
+**Description:**
+This Docker image provides a Flask application that acts as a proxy to convert YouTube channel RSS feeds to a more accessible format. It uses a simple Flask API to expose an endpoint that takes a YouTube channel name as a parameter and returns the channel's RSS feed.
+
+**Usage:**
+
+- **Pull the Docker Image:**
+  ```bash
+  docker pull [username/repository-name:tag]
+  ```
+
+- **Run the Docker Container:**
+  ```bash
+  docker run -p 5000:5000 -e youtube-proxy=[your_proxy_url] bramkel/youtuberss/latest
+  ```
+  - Replace [your_proxy_url] with the URL of your preferred YouTube proxy (default is 'https://www.youtube.com').
+  - The application will be accessible at http://localhost:5000/[channelName].
+  
+- **API Endpoint:**
+  - /[channelName]: Returns the converted RSS feed for the specified YouTube channel.
