GitHub and VS Code how to create my own project and link the repository, etc.?

Question

GitHub

1) How does github work? I read, looked, I kind of understood about the commits branches, but they wrote to me "create a project on github and send a link", in my understanding , each project should have a separate master channel, is that right ? I created a project on github, but I don’t understand how to add something there, there is only "add column", you make columns, and there are only comments in the columns .. And there seems to be a button to link the repository, but the https link to my repository does not work, link button not working...
2) I want to make a separate folder in vs code as a separate project, and another folder as another project, but when I go to the github there, everything is not in the folders .. it shows the latest changes, and there are 83 files .. I'm afraid if I’ll save it, then all this extra stuff will fly away to github, how can I create my own project from vs code and is it possible? And the repository is created only on github and then added somehow to vs code? on the git command line?
UPDATE:
as I understand it, "projects" are stupid notes ..... I didn’t understand how to work with vs code with github, just how to track a specific folder, where to insert a link to the repository

Answer 1

You need to create a new project from the git repository, and there should be a set of utilities for working with git, and drag all files into an empty git project, then configure gitignore - so that nothing left flies to git. Make the first commit and upload to github.
