 # ==============================================================================
 # Script Description:
 # This script connects an existing local directory to a remote Git repository.
-# It requires the SSH URL of the Git repository as an input argument.
 # 
 # Process:
 # 1. Initializes a new local Git repository.
-# 2. Adds the provided URL as the remote 'origin'.
+# 2. Adds the remote 'origin'.
 # 3. Fetches the remote repository data.
-# 4. Checks for differences between the local files and 'origin/master'.
-# 5. If there are no differences, it sets up tracking for the master branch
-#    and performs a hard reset to synchronize exactly with the remote.
-#
-# Usage:
-#   ./connect_git.sh <repository-ssh-url>
-#
-# Example:
-#   ./connect_git.sh git@github.com:username/repository.git
+# 4. Stages local files to check differences.
+# 5. Identifies real changes bypassing the Git --name-only whitespace bug.
+# 6. Prompts to override local files if diffs are found.
