 ## Code Usage 
 
 ```
 require 'cert_checker'
 
-status, host, issuer, expired, desc = CertChecker.check('taobao.com')
+status, host, issuer, expired, desc, alpn_protocol = CertChecker.check('taobao.com')
 
 # Other port and timeout
 port = 443 # default
-status, host, issuer, expired, desc = CertChecker.check('taobao.com', port, timeout: 5)
+status, host, issuer, expired, desc, alpn_protocol = CertChecker.check('taobao.com', port, timeout: 5)
 ```
 
 **Add your root cert**
 
 ```
 CertChecker.cert_store.add_cert(root_ca)
 
 # It will trust certs which signed by this root ca
-status, host, issuer, expired, desc = CertChecker.check('mydomain.com', port, timeout: 3)
+status, host, issuer, expired, desc, alpn_protocol = CertChecker.check('mydomain.com', port, timeout: 3)
 ```
 
 **Multiple cert store instance**
 
 ```
 class MyChecker
   include CertChecker
 end
 
 MyChecker.cert_store.add_cert(root_ca)
-status, host, issuer, expired, desc = MyChecker.check('mydomain.com', port, timeout: 3)
+status, host, issuer, expired, desc, alpn_protocol = MyChecker.check('mydomain.com', port, timeout: 3)
