 ## Where to get your api-key?
 
-CodeBox is currently in early development so I created a stripe payment link as login system:
-https://pay.codeboxapi.com/b/00g3e6dZX2fTg0gaEE
-As BetaTester you get 70% with the code `BETA`. 
-Bear in mind, we don't have many automations set up right now, 
-so you'll need to write an [email](mailto:[email protected]) for things like refunds,
