This Library Intergration project is based the file named "en.stm32g0_cad.zip" on [st official website]{https://www.st.com/resource/en/cad_symbol_library/stm32g0_cad.zip}. I build it using Altium Designer 2019, but I think you can use the intergration file on any altium designer version (version > 10).

There is some different information between official device information and devices list here. There are some devices can not be find on official website for now.
Find the official devices here:
I plan to modify bugs when use and update new devices when it have.
