You probably can click out some basic USART-related functions in CubeMX, or have a look at the USART-related examples in CubeF0 ("firmware").
I don't use Cube/CubeMX.
You could also write it yourself. You would need to set one USART Tx pin by setting it to AF (0b10) in respective bits in GPIOx_MODER, and the set it to required AF in GPIOx_AFR (have a look at the alternative functions table in datasheet (DS) for your chip) (working with GPIOx registers assumes you have already enabled clock for that GPIOx in RCC); then you would need to enable clock for given USART in RCC, set its baudrate in its baudrate register (USARTx_BRR), enable Tx and enable UART in USARTx_CR1, and then transmit characters by looking first at the TXE bit in USARTx_SR and then writing the given character into USARTx_TDR.

It's a debug module (in Cortex-M3/M4/M7), which can be used also as a simple serial port and that's how most of the users use it.
