How to close a repo, work on it and upload it to Github as a different repo

github.js

// GitHub: git clone someone else's repository & git push to your own repository

// Create a new repository at github.com. (this is your repository)

// Give it the same name as the other repository.
// Don't initialize it with a README, .gitignore, or license.
// Clone the other repository to your local machine. (if you haven't done so already)

// git clone https://github.com/other-account/other-repository.git
// Rename the local repository's current 'origin' to 'upstream'.

// git remote rename origin upstream
// Give the local repository an 'origin' that points to your repository.

// git remote add origin https://github.com/your-account/your-repository.git
// Push the local repository to your repository on github.

// git push origin master
