 ## Quick Start
 
 ```bash
 # 1. Backup skills to GitHub
-skills-manager push
+sm push
 
 # 2. Restore on a new machine
-skills-manager pull --repo owner/my-skills
+sm pull --repo owner/my-skills
 
 # 3. Re-link skills to agents (auto-runs after pull)
-skills-manager link
+sm link
 
 # 4. Link skills to current project directory
-skills-manager link --project
+sm link --project
 ```
