(Tee hee hee xd) They go wherever your working directory was when you entered `git clone` -- since you are using windows and I don't know which tutorial you used, I am going to assume you somehow have the git CLI tool working in a cmd.exe environment, which means that to see your current working directory, you would type "dir" in cmd.exe and then enter. If you closed cmd.exe after cloning however, then your working directory will have been reset and there is no way to know where you were when you cloned the repo. The default working dir is always your home directory (eg. on Windows C:\Users\<username>\.), so if you never changed it before cloning, then the local repo should be in your home folder at C:\Users\<username>\.

Alright so... did you complete the environment setup section successfully? Meson should be installed by pip by the time you are calling it obviously

I don't believe you -- if you installed meson with pip and it completed successfully like you say, it should be in your PATH and execute successfully in a command prompt. What was output after running "python -m pip install -U meson"?
