Step by step build

I am eager to start building a kegbot but due to financial constraints I cannot buy and build all at once

I would like to start by using RFID with limits per person using water for a start

I would say I am technically savvy and can follow instructions well

could someone please point me in the right direction

PS:I have read through the whole site but I am confused

start here for parts

then figure out what is going to run the back end server, ie cloud serve like digital ocean, raspberry pi, or dedicated Linux machine.

Front end app can use NFC for user authentication, but the app doesn’t natively support limits for users. Since the project is oipen source you could write it to do so.
