Creating a check and running it (Writing check50 checks).
(1) Create a git repo. Your new repo should live at https://github.com/< user >/< repo >.
(2) Create the .cs50.yaml file. All indentation is done by 2 spaces, as per YAML syntax.
(3) Simply execute: check50 < owner >/< repo >/master/example --local
Where you substitute < owner > for your own username, < repo > for the repo you’ve just created = Running_check50, master = main.
(4) That’s it! You know have a repo that check50 can use to check whether a python file called hello.py prints Hello, world! and exits with a 0 as exit code.
