 ### Symlink Mode

 **Why use symlink mode?**
+
 - Changes to source files instantly reflect in all agent configs (no need to run `glooit sync`)
 - Single source of truth - edit once, all agents see the update
 - Useful for rapid iteration and development
 
 **Limitations:**
 Symlinks point directly to source files, so transformations cannot be applied:
+
 - Per-rule hooks and global transforms are skipped (hooks/transforms would modify the source file)
 - Merge rules (`file: string[]`) automatically fall back to copy mode (cannot symlink to multiple files)
 - Agent-specific formatting is not applied (each agent would need a different version)

+### Link Command
+
+The `link` command provides zero-config symlink-based syncing without requiring a config file:
+
+```bash
+glooit link              # Auto-detect .agents/ or .glooit/ and sync to all agents
+glooit link .my-rules    # Use custom source directory
+glooit link -t claude,cursor  # Sync to specific agents only
+```
+
+It automatically discovers and symlinks:
+
+- `CLAUDE.md` → Claude Code
+- `AGENTS.md` → Codex, OpenCode, Factory
+- `commands/` → All agents that support commands
+- `skills/` → All agents that support skills
+- `agents/` → All agents that support agents/droids

 ### Upgrade
 
 The `upgrade` command auto-detects your package manager and whether glooit is installed locally or globally:
