You can specify the permalinks for your posts and pages in config.yml file in template folder.

Template Variables for Posts

Variable	Description
year	year from the post's front matter or filename
month	month from the post's front matter or filename
day	day from the post's front matter or filename
title	the title of the post from its front matter
name	the name of the post from its file name

Template Variables for Pages

Variable	Description
title	the title of the page from its front matter
name	the name of the page from its file name

Default Permalink Values

Setting	Permalink
post_link	post/:year/:month/:day/:name.html
page_link	page/:name

For example, when the file name of some post is some-name.md, the name value of it is some-name; when the file name of another post is 2013-06-11-another-name.md, the name value of it is another-name. It is better to use these name values in permalinks if there are Non-ASCII characters in the title of posts or pages.
