 Alternatively, you can use it directly from the CLI by using `deno run`:
 
 ```bash
-deno run https://deno.land/x/scrypt/cli.ts hash <password>
-deno run https://deno.land/x/scrypt/cli.ts verify <password> <hash>

 You can also install it globally using the following:
 
 ```bash
-deno install -n scrypt https://deno.land/x/scrypt/cli.ts
+deno install -n scrypt https://deno.land/x/scrypt@v4.1.0/cli.ts
 ```
 
 Then, the package is available to run:
