+Currently, only the encrypt and verify methods are implemented for Argon2i.
 
 To hash a password:
 ```js
 var argon2 = require('argon2');
 
-argon2.encrypt('password', 'somesalt', function(err, hash) {
+argon2.encrypt('password', 'somesalt', function (err, hash) {
   if (err) // encryption failure
     throw err;
 
   doSomethingWith(hash);
 });
+
+// OR
+
+try {
+    var hash = argon2.encryptSync('password', 'somesalt');
+} catch (err) {
+    console.log(err);
+}
 ```
 Resultant hashes will be 90 characters long.
 
 To verify a password:
 ```js
 var argon2 = require('argon2');
 
-argon2.verify('<big long hash>', 'password', function(err) {
+argon2.verify('<big long hash>', 'password', function (err) {
   if (err) // password did not match
     throw err;
 
   authenticate();
 });
+
+// OR
+
+if (argon2.verifySync('<big long hash>', 'password')) {
+  authenticate();
+} else {
+  fail();
+}
 ```
