Workflow 1

Setup a local repository and push it on Github (new project)
 
#staging all the files
git add .
 
#commit the statged files
git commit -m "first commit"

Now, you need to create a repository on GitHub - https://github.com/new

#add the remote url
git remote add origin https://github.com/username/repo_name
 
#if your branch is master on local, change it to main
git branch -m master main
 
#push the files on GitHub
git push origin main

Workflow 2

You already have a local repository; you want it to add a remote repository on it

#staging all the files
git add .
 
#commit the statged files
git commit -m "first commit"
 
#add the remote url
git remote add origin https://github.com/username/repo_name
 
#if your branch is master on local, change it to main
git branch -m master main
 
#push the files on GitHub
git push origin main

Workflow 3

You already have a repository on GitHub, and now you want to set it up on your local computer.

 
#clone the repository on your local computer
git clone https://github.com/username/repo_name
 
#After changing your files, you can stage files
git add .
 
#commit the staged files
git commit -m "new commit"
 
#push the files on GitHub
git push
