Connecting Raspberry Pi to WeatherBoard using Pin Headers

I am currently trying to complete the project "Connecting a Raspberry Pi 3 Model B to the WeatherBoard using Pin Headers (3.3v)" and I am having trouble installing the software from Github on my Raspberry Pi. All my wiring is complete and I am trying to use the software from Github to run the setup. So far I have used the "git clone github.com/switchdoclabs/SDL_Pi_WeatherBoard" command from the command line as well as completed the set listed in the ReadMe for the OLED and AM2315 support. This created a new directory called SDL_Pi_WeatherBoard, however I am not sure what to do after this. The ReadMe says to test the code type in: "Sudo python WeatherBoard.py", so I entered the SDL_Pi_WeatherBoard directory and entered the command, however when I do this I am told there is no such file or directory. When I performed the "git clone" function, does this install as well, or am I missing a step here?

I am essentially asking for the steps to get the project up and running after I connect all the wiring.

Thank you for your help, I am not yet proficient with using my Raspberry Pi and I could not seem to find the proper support on the website.
