Tutorial For me

You’ll find this post in your _posts directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run jekyll serve, which launches a web server and auto-regenerates your site when a file is updated.

To add new posts, simply add a file in the _posts directory that follows the convention YYYY-MM-DD-name-of-post.ext and includes the necessary front matter. Take a look at the source for this post to get an idea about how it works.

Jekyll also offers powerful support for code snippets:

def print_hi(name)
  puts "Hi, #{name}"
end
print_hi('Tom')
#=> prints 'Hi, Tom' to STDOUT.

Check out the Jekyll docs for more info on how to get the most out of Jekyll. File all bugs/feature requests at Jekyll’s GitHub repo. If you have questions, you can ask them on Jekyll Talk.

Great heading (h1)

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Fusce bibendum neque eget nunc mattis eu sollicitudin enim tincidunt. Vestibulum lacus tortor, ultricies id dignissim ac, bibendum in velit.

Some great heading (h2)

Proin convallis mi ac felis pharetra aliquam. Curabitur dignissim accumsan rutrum. In arcu magna, aliquet vel pretium et, molestie et arcu.

Praesent varius interdum vehicula. Aenean risus libero, placerat at vestibulum eget, ultricies eu enim. Praesent nulla tortor, malesuada adipiscing adipiscing sollicitudin, adipiscing eget est.

Another great heading (h2)

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Fusce bibendum neque eget nunc mattis eu sollicitudin enim tincidunt. Vestibulum lacus tortor, ultricies id dignissim ac, bibendum in velit.

Some great subheading (h3)

Proin convallis mi ac felis pharetra aliquam. Curabitur dignissim accumsan rutrum. In arcu magna, aliquet vel pretium et, molestie et arcu. Mauris lobortis nulla et felis ullamcorper bibendum.

Phasellus et hendrerit mauris. Proin eget nibh a massa vestibulum pretium. Suspendisse eu nisl a ante aliquet bibendum quis a nunc.

Some great subheading (h3)

Praesent varius interdum vehicula. Aenean risus libero, placerat at vestibulum eget, ultricies eu enim. Praesent nulla tortor, malesuada adipiscing adipiscing sollicitudin, adipiscing eget est.

This quote will change your life. It will reveal the secrets of the universe, and all the wonders of humanity. Don’t misuse it.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Fusce bibendum neque eget nunc mattis eu sollicitudin enim tincidunt.

Some great subheading (h3)

Vestibulum lacus tortor, ultricies id dignissim ac, bibendum in velit. Proin convallis mi ac felis pharetra aliquam. Curabitur dignissim accumsan rutrum.

<html>

In arcu magna, aliquet vel pretium et, molestie et arcu. Mauris lobortis nulla et felis ullamcorper bibendum. Phasellus et hendrerit mauris.

You might want a sub-subheading (h4)

In arcu magna, aliquet vel pretium et, molestie et arcu. Mauris lobortis nulla et felis ullamcorper bibendum. Phasellus et hendrerit mauris.

In arcu magna, aliquet vel pretium et, molestie et arcu. Mauris lobortis nulla et felis ullamcorper bibendum. Phasellus et hendrerit mauris.

But it’s probably overkill (h5)

In arcu magna, aliquet vel pretium et, molestie et arcu. Mauris lobortis nulla et felis ullamcorper bibendum. Phasellus et hendrerit mauris.

Oh hai, an unordered list!! (h6)

In arcu magna, aliquet vel pretium et, molestie et arcu. Mauris lobortis nulla et felis ullamcorper bibendum. Phasellus et hendrerit mauris.

  • First item, yo
  • Second item, dawg
  • Third item, what what?!
  • Fourth item, fo sheezy my neezy

Oh hai, an ordered list!!
