Setting up bandwith manager and htspot

Greetings to all

I have a mikrotik RB750 and I would like to setup the hotspot, so the users may need to enter username and password to login, before I had a person who installed me this fixture, but that person isn’t working anymore with my internet provider, and it seems they don’t have anyone capable to do it, its very important to my hotel to have this setting enabled so that I can control who is connected and what bandwith they can use.
If you can help me with this please let me know.

i was very happy with the router before, but then it got broken and i had to replace it, now i don’t know eher to go to make the settings.

many thanks

The manual contains all the information that you need to get started at least setting it up.
