While using hexo blogging system or other blogging system like: Octopress, Jekyll, one of the most important thing is to learn markdown syntax. I don’t define it as language, because it is easy to use. The philosophy of this language is the simple the better.

Alternatively, for H1 and H2, an underline-ish style:

#Emphasis

Emphasis, aka italics, with asterisks or underscores.
Strong emphasis, aka bold, with asterisks or underscores.
Combined emphasis with asterisks and underscores.
Strikethrough uses two tildes. Scratch this.

#Listing

1. First ordered list item
2. Another item
• Unordered sub-list. (a tab before the next level list)
3. Actual numbers don’t matter, just that it’s a number
1. Ordered sub-list
4. And another item.
• Unordered list can use asterisks
• Or minuses
• Or pluses

#Codes

Inline code has back-ticks around it.

There are two ways to create links.
