I love Markdown. I love it so much that after using it for a project I completely forgot about it.

Snark aside, bulletin boards and old forum software used to use markdown exclusively for posts in the early 00s. But this isn't just old tech.

I all but forgot about it until I decided to give Trello a whirl. Trello is an online project management application that focuses on laying out the information in complete view. It's an interesting take on collaboration and productivity.

And to be clear, I really do love Markdown!

How Text is Formatted in Your Trello Cards

Trello uses a modified version of the simple language used to format plaintext called Markdown.

Using Markdown syntax, you can add format to plaintext such as lists, paragraphs, headers, and more just like you can with HTML text. It's a pretty neat little project.

You can read more about Markdown at Daring Fireball.

Wrap Up

Another good Markdown resource is at Markdown Guide. They are a free and open-source reference guide on how to use Markdown. It lays everything out in a super easy to read and easy to understand manner. I dig it.
