 ## Usage
 This command will generate ISC `LICENSE` file in your current directory, including current year, and your name read from Git configuration:
 ```bash
-licensmith add ISC
+licensmith --license ISC
 ```
 
 By default, Licensmith read your local repository looking for user details (name and e-mail), as a fallback it uses global configuration.
 
 You can also specify different values using:
 ```bash
-licensmith add ISC --name "John Doe" --email "jdoe@example.com"
+licensmith --license ISC --name "John Doe" --email "jdoe@example.com"
 ```
 
 To list available templates run:
 ```bash
-licensmith list
+licensmith --list
 ```
