The existing commands can be simply run via the CLI terminal of VS-CODE. It is understood that Git is installed in the system, configured with desired username and email Id. https://code.visualstudio.com/docs/editor/github
git init
git add . //for adding all your code for commit. if already done just ignore it
2) Once that is successful, click on the 'Source Control' icon on the left navbar in VS-Code.One should be able to see files ready to be commit-ed. Press on 'Commit' button, provide comments, stage the changes and commit the files. Alternatively you can run from CLI
git commit -m "Your comment"
3) Now you need to visit your GitHub account and create a new Repository. Exclude creating 'README.md', '.gitIgnore' files. Also do not add any License to the repo. Sometimes these settings cause issue while pushing in.
git remote add origin <Link to GitHub Repo> //maps the remote repo link to local git repo
git remote -v //this is to verify the link to the remote repo
git push -u origin master // pushes the commit-ed changes into the remote repo
Note: If it is the first time the local git account is trying to connect to GitHub, you may be required to enter credentials to GitHub in a separate window.
6) You can see the success message in the Terminal. You can also verify by refreshing the GitHub repo online.
Hope this helps
