 ## 2. Usage
 
 ### 2.1 DDNS Update
 ```
-cf ddns [--force]
+./cf ddns [--force]
 ```
 Updates all domains with current IP. Use `--force` to update regardless of IP change.
 
 ### 2.2 Adding/Updating Domain Configuration
 ```
-cf <full-domain> [--ip <ip address>] --port <port>
+./cf <full-domain> [--ip <ip address>] --port <port>
 ```
 Adds or updates domain in Cloudflare and Caddyfile. Default IP is localhost.
 
 ### 2.3 Updating All Domains
 ```
-cf all [--force]
+./cf all [--force]
 ```
 Updates all domains and Caddyfile configurations.
 
+Note: If you created the symlink, you can use `cf` instead of `./cf` from any directory.
