Guide to setting up github

git.sh

git config --global user.name "Your Name"
git config --global user.email "[email protected]"
git config --global init.defaultBranch main
ssh-keygen -t ed25519 -C <youremail>
cat ~/.ssh/id_ed25519.pub 
#copy the whole output 
#Add SSH key to github [https://github.com/settings/keys]

#Copy your repo's SSH url. 
git clone [email protected]:USER-NAME/REPOSITORY-NAME.git 
#TO ADD LOCALLY CREATED FOLDER
git init -b main
git add . && git commit -m "initial commit"
or git remote add origin [email protected]:USER-NAME/REPOSITORY-NAME.git

#Pushing is as simple as 
git push origin {branch_name}

#flow is:
#branching
git branch
git switch branch_name
#branching
git add .
git commit -m "msg"
git push

Prefer creating a new repo then cloning its .git file and then pushing using it to avoid headaches.
