Done with bachelors, no idea about money.

I now have my first full time job as a fullstack-dev in Germany and i make around 45.000€ A year (pre tax) with a usual bonus of around 9000 a year. How do i get informed about saving money, how investing works and in general how to use money? Every single time I try to inform my self I seem to find myself in a discussion between two extremes and its disorienting.
