Github Pages

gh-pages

To get started with gh-pages, you should know what gh-pages is first. If you know, proceed here..
Supposing you already have a git repo open on your terminal with the default branch, master

To switch to a new branch, gh-pages:
git checkout --orphan gh-pages

--orphan creates a branch gh-pages with no parent. 

Now you would wanna remove all files from the old working tree:
git rm -rf .

Now, you are in gh-pages branch and you have an empty repo.
Create a file, say index.html
Write a few html codes in it. And then push it:

git push origin gh-pages


Now, you're page would be displayed on [yourusername].github.io/reponame

In case you might wanna switch back to your master branch:
git checkout master


Deleting a local branch
git branch -D <branchname>

Deleting from remote branch
git push origin --delete <branchname>
