+OpenLLM Training Space Application
+
+This Gradio application provides a comprehensive web-based user interface for
+training OpenLLM models within the Hugging Face Space environment. It serves
+as the main entry point for users to interact with the training infrastructure
+and monitor training progress.
+
+The application features:
+- Interactive training configuration interface
+- Real-time training status monitoring
+- Progress tracking and visualization
+- Comprehensive instructions and documentation
+- Integration with Hugging Face Hub for model distribution
+
+Key Components:
+1. Training Configuration Panel - Model size, hyperparameters, and settings
+2. Training Status Monitor - Real-time progress and status updates
+3. Instruction Panel - Step-by-step guidance for users
+4. Terminal Commands Display - Manual command execution options
+5. Resource Links - Quick access to related repositories and documentation
+
+This application is designed to work seamlessly within the Hugging Face Space
+environment and provides both automated and manual training capabilities.

+        Follow these steps to successfully train your OpenLLM model:
+        
+        ### **Step 1: Configure Parameters**
+        - Select the appropriate model size for your computational resources
+        - Set the number of training steps based on your requirements
+        - Adjust the learning rate for optimal training performance
+        - Choose a batch size that fits your available memory
+        
+        ### **Step 2: Upload Training Data**
+        - Use the terminal to upload your training dataset
+        - Ensure your data is properly formatted and cleaned
+        - Verify that the dataset is accessible to the training process
+        
+        ### **Step 3: Start Training**
+        - Click the "Start Training" button to begin the process
+        - Monitor the progress bar and status updates
+        - The training will run automatically in the background
+        
+        ### **Step 4: Monitor Progress**
+        - Watch the real-time status updates
+        - Check the progress bar for completion percentage
+        - Review any error messages or warnings
+        
+        ### **Step 5: Access Results**
+        - Trained models are automatically pushed to Hugging Face Hub
+        - Check the model repository for your trained model
+        - Download or use the model for inference tasks
