人生在世，看得透，又看得远者prevail everywhere. v.gd/YLHADG v.gd/cRqvfD v.gd/bKvfFH v.gd/sRm3tA: 在Github Pages上，创建Project Page

It’s very to create the web page for your new repository under your mainpage. Here, I record the procedure.

Create a New Reposity

You can easily create a new reposity in Github. At the left bottom corner of the main page of github, you can find your repositories. A “New reposity” button is there!
Enter the name, describe your project, and choose whether create .gitingore file and license file. Then, create the new project.
Copy the SSH address of your project, and git clone git@github.com:username/projectname.git clone the project with its address to local. It’s not nessessary.

The most easy way is to create the branch gh-pages online as the figure shown above. Enter the new name and github will remind you to create a new branch for it.
You can also do that in command line by git: git checkout --orphan gh-pages, it will create a new branch without parent. If you want to create a blank branch only contains the project page, you can git rm -rf . to delete all the current files. I don’t think it’s nessesary indeed. It only need you to have a branch called gh-pages, that’s enough. git push -u origin gh-pages to create your branch on remote.
You can also change the default branch to gh-pages on repository setting. It will help you to change to gh-pages when you clone the repository.

To create a simple index.html file online/on git is easy. But don’t fancy.
Use Jekyll! Yes, you can copy the jekyll needed files from your mainpage to the project page, such as _config.yml file, _layouts, _includes directory and even .gitignore CNAME 404.md files when you need. Because Jekyll need them to help you to convert markdown file to a page. If you don’t copy these from your mainpage repository, the markdown file doesn’t work at all!
CSS/JS files don’t need to be copied. Because the page can use them as its mainpage.
Now you can visit http://username.github.io/projectname to visit the project page!
