+# Quick start
+
+1.) install nightly node js
+    - easiest way is to install a node js version from nodejs.org and run "npx n nightly" to install nightly version.
+2.) check out the config options, e.g. for google ldap, download your certificates from http://admin.google.com/ -> Apps -> LDAP -> Client
+download the files and name them "ldap.gsuite.key" and "ldap.gsuite.crt" accordingly.
+3.) switch to this directory and run "npx radius-server -s YourRadiusSecret"
+4.) Log into your WLAN Controller and configure the radius server to your newly running radius
+5.) On your clients, just connect to the WLAN, the clients should figure out the correct method by their own,
+if they don't use: WPA2-Enterprise -> EAP-TTLS -> PAP / CHAP
+6.) Log in via your google credentials (email + password, ... e.g. youremail@yourcompany.com)

 ## Known Issues / Disclaimer
 
 This is a first implementation, which is currently only working with node js nightly (node 13+) (see https://github.com/nodejs/node/pull/31814).
