+There are many ways to extend `verdaccio`, currently we only support `authentication plugins`
+
+## Authentication Plugins
+
+This section will describe how it looks like a Verdaccio plugin in a ES5 way. Basically we have to return an object with a single method called `authenticate` that will recieve 3 arguments (`user, password, callback`). Once the authentication has been executed there is 2 options to give a response to `verdaccio`.
+
+##### OnError
+
+Either something bad happened or auth was unsuccessful.
+
+    callback(null, false)
+    
+
+##### OnSuccess
+
+The auth was successful.
+
+`groups` is an array of strings where the user is part of.
+
+     callback(null, groups);
+    
+
+### Example
+
+```javascript
+function Auth(config, stuff) {
+  var self = Object.create(Auth.prototype);
+  self._users = {};
+
+  // config for this module
+  self._config = config;
+
+  // verdaccio logger
+  self._logger = stuff.logger;
+
+  // pass verdaccio logger to ldapauth
+  self._config.client_options.log = stuff.logger;
+
+  return self;
+}
+
+Auth.prototype.authenticate = function (user, password, callback) {
+  var LdapClient = new LdapAuth(self._config.client_options);
+  ....
+  LdapClient.authenticate(user, password, function (err, ldapUser) {
+    ...
+    var groups;
+     ...
+    callback(null, groups);
+  });
+};
+
+module.exports = Auth;
+```
