 ### The Git Workflow
 
-1. Working Directory: Where you modify files
-2. Staging Area: Where you prepare changes for commit
-3. Repository: Where Git stores the committed history

+- **Working Directory**: Where you modify files
+- **Staging Area**: Where you prepare changes for commit
+- **Commit**: Snapshot of your project
+- **Branch**: Independent line of development
+- **Remote**: Connection to a repository hosted elsewhere
