_layout folders contains different kinds of pages in this web sites.
_includes folders contains headers, footers, and icon things. Therefore, if we want to add some pages here, we should first analyse the head.html, and header.html files here.
{% highlight ruby %}
% for my_page in site.pages %
% if my_page.title %
my_page.title | escape
% endif %
% endfor %
{% endhighlight %}
Here the site.pages means the markdown files in root folder. So that I recognize that if I build up a new text file, and rename as “what you-want to display on your site.md”, I can add another pages in the header.
Then I open the file, and write down:
{% highlight ruby %}#
title: About permalink: /about/#
somthing you want to write down in this page.
{% endhighlight %}
The most important thing is that the layout style must be page. The title will be presented at the header of pages.
