 OpenLLM Training Script with Hugging Face Authentication
 
-This script includes proper authentication setup for Hugging Face Spaces
-and handles model upload after training completion.
-
-Features:
-- Automatic authentication using GitHub secrets
-- Model training with proper error handling
-- Automatic model upload to Hugging Face Hub
-- Model card and configuration generation
-
-Usage:
-    Add this to your Space and run it for training with automatic upload.
+This script runs OpenLLM training in a Hugging Face Space environment.
+It uses the Space's own access token for authentication and model uploads.
