-- supports LDAP Authentification Backend
-- supports WPA2 Enterprise (TTLS over PAP)
+easy extensible NodeJS RADIUS Server
+
+- supports different authentification backends
+    - LDAP (e.g. for Google LDAP Service, but also any other LDAP service)
+    - HTTP
+    - IMAP
+    - SMTP
+    - Predefined / Static username and password
+- supports WPA2 Enterprise

-# Quick start
+## Introduction
+
+This app provides a radius server to authenticate against an authentication service. To get this running
+you need:
+
+1.  An running Auth Service (e.g. LDAP Service / Google Suite Enterprise / Gloud Identity Premium)
+2.  Optional: Create your own SSL certificate (e.g. self signed via npm run create-certificate)
+3.  Check config.js and adapt to your needs
+
+- configure authentication:
+  set authenticaiton to one of the [provided authenticators](src/auth/README.md), e.g.:
+
+```js
+var config = {
+	// ....
+	authentication: 'GoogleLDAPAuth',
+	authenticationOptions: {
+		base: 'dc=hokify,dc=com'
+	}
+};
+```
+
+- set radius secret
+
+4.  Install und build server: npm install && npm run build
+5.  Start server "npm run start"
+
+# Quick start for using it with Google LDAP
