The README says "If you are developing with PlatformIO then simply use the library manager to install brzo_i2c". That brzo_i2c link takes you to a generic page that is not helpful. The actual name of the package, as would be used in a "lib_deps" field in platformio.ini, is "pasko-zh/Brzo I2C". So I think it would be clearer to say:
If you are developing with PlatformIO then add pasko-zh/Brzo I2C to lib_deps in platformio.ini
