What is Markdown?
Markdown is a way to style text on the web. You control the display of the document; formatting words as bold or italic, adding images, and creating lists are just a few of the things we can do with Markdown. Mostly, Markdown is just regular text with a few non-alphabetic characters thrown in, like
You can use Markdown most places around GitHub:
- Comments in Issues and Pull Requests
- Files with the

Here’s an overview of Markdown syntax that you can use anywhere on GitHub.com or in your own text files.

GitHub Flavored Markdown
GitHub.com uses its own version of the Markdown syntax that provides an additional set of useful features, many of which make it easier to work with content on GitHub.com.
Note that some features of GitHub Flavored Markdown are only available in the descriptions and comments of Issues and Pull Requests. These include @mentions as well as references to SHA-1 hashes, Issues, and Pull Requests. Task Lists are also available in Gist comments and in Gist Markdown files.
Here’s an example of how you can use syntax highlighting with GitHub Flavored Markdown:
You can also simply indent your code by four spaces:
Here’s an example of Python code without syntax highlighting:
If you include a task list in the first comment of an Issue, you will get a handy progress indicator in your issue list. It also works in Pull Requests!
You can create tables by assembling a list of words and dividing them with hyphens
- (for the first row), and then separating each column with a pipe
|First Header||Second Header|
|Content from cell 1||Content from cell 2|
|Content in the first column||Content in the second column|
Any reference to a commit’s SHA-1 hash will be automatically converted into a link to that commit on GitHub.
Issue references within a repository
Any number that refers to an Issue or Pull Request will be automatically converted into a link.
@ symbol, followed by a username, will notify that person to come and view the comment. This is called an “@mention”, because you’re mentioning the individual. You can also @mention teams within an organization.
Automatic linking for URLs
Any URL (like
http://www.github.com/) will be automatically converted into a clickable link.
Any word wrapped with two tildes (like
~~this~~) will appear crossed out.
GitHub supports emoji!

This almost certainly has to do with line endings.
Most people have likely included a line ending at the end of the first line. Therefore the file contains a second blank line. A few users did not add a line ending (using the
[return] key). Therefore, their file contains one line.
Github Markdown Code Language
Generally it is considered good form to include a line ending at the end of the last line of a plain text file. In fact, many text editors will automatically add one for you, which is probably why most of the files contain two lines. That said, any decent Markdown parser should be able to properly parse a Markdown file missing a line ending on the last line.
Github Markdown Language Syntax
As for the difference in file size (when there are no typos), this is also likely due to line endings. On Windows (DOS), the system default is to use two (hidden) characters to represent a line ending (usually represented as
rn). Whereas all other systems (Mac OS, Linux, Unix, etc) only use a single character (
n). Again, any decent Markdown parser should be able to handle either. But, each gives a different character count and therefore a different file size.
