Battery level on stm32l0xx

hey

First of all I want to say that I'm new here, I'm currently learning a lot about the stm32 but please don't be frustrated if I ask stupid questions . This is my question:

I have a stm32l0xx microcontroller, I'm programming in C and I want to be able to log the battery level. Only problem is that I don't know where to start. Can someone point me in the right direction, or help me with this? I've found some implementations for the stm32F0xx series but i don't know if that will work on my controller.

Thanks for the help
