Not able to make changes happen at Github

I am learning how to use GitHub action on CI.
Tried deleted the git init and performed the following steps without avail:

BlockquoteC:\Users\karen\Udacity And SUSE Cloud Native\Lesson 5 - CICD\python-helloworld>git init
Initialized empty Git repository in C:/Users/karen/Udacity And SUSE Cloud Native/Lesson 5 - CICD/python-helloworld/.git/

C:\Users\karen\Udacity And SUSE Cloud Native\Lesson 5 - CICD\python-helloworld>git remote add origin master GitHub - karenworld/python-helloworld: test CI with Github action
usage: git remote add []

-f, --fetch           fetch the remote branches
--tags                import all tags and associated objects when fetching
                      or do not fetch any tag at all (--no-tags)
-t, --track <branch>  branch(es) to track
-m, --master <branch>
                      master branch
--mirror[=(push|fetch)]
                      set up remote as a mirror to push to or fetch from

C:\Users\karen\Udacity And SUSE Cloud Native\Lesson 5 - CICD\python-helloworld>git push origin master
fatal: ‘origin’ does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

C:\Users\karen\Udacity And SUSE Cloud Native\Lesson 5 - CICD\python-helloworld>git pull origin master
fatal: ‘origin’ does not appear to be a git repository
fatal: Could not read from remote repository.

My aim is to make the branch python-hello in my repo renewed with the commit which is a folder named github that has a folder workflow but no matter what I did, my repo doesn’t change at all.

What did I miss ?
