You can add Markdown formatting elements to a plaintext file using a text editor application. Or you can use one of the many Markdown applications for macOS, Windows, Linux, iOS, and Android operating systems. There are also several web-based applications specifically designed for writing in Markdown.
Depending on the application you use, you may not be able to preview the formatted document in real time. But that's okay. According to Gruber, Markdown syntax is designed to be readable and unobtrusive, so the text in Markdown files can be read even if it isn't rendered.
The overriding design goal for Markdown's formatting syntax is to make it as readable as possible. The idea is that a Markdown-formatted document should be publishable as-is, as plain text, without looking like it's been marked up with tags or formatting instructions.
You might be wondering why people use Markdown instead of a WYSIWYG editor. Why write with Markdown when you can press buttons in an interface to format your text? As it turns out, there are a couple different reasons why people use Markdown instead of WYSIWYG editors.
Markdown is portable. Files containing Markdown-formatted text can be opened using virtually any application. If you decide you don't like the Markdown application you're currently using, you can import your Markdown files into another Markdown application. That's in stark contrast to word processing applications like Microsoft Word that lock your content into a proprietary file format.
Markdown is platform independent. You can create Markdown-formatted text on any device running any operating system.
Markdown is future proof. Even if the application you're using stops working at some point in the future, you'll still be able to read your Markdown-formatted text using a text editing application. This is an important consideration when it comes to books, university theses, and other milestone documents that need to be preserved indefinitely.
Markdown is everywhere. Websites like Reddit and GitHub support Markdown, and lots of desktop and web-based applications support it.
The best way to get started with Markdown is to use it. That's easier than ever before thanks to a variety of free tools.
You don't even need to download anything. There are several online Markdown editors that you can use to try writing in Markdown. Dillinger is one of the best online Markdown editors. Just open the site and start typing in the left pane. A preview of the rendered document appears in the right pane.
You'll probably want to keep the Dillinger website open as you read through this guide. That way you can try the syntax as you learn about it. After you've become familiar with Markdown, you may want to use a Markdown application that can be installed on your desktop computer or mobile device.
Dillinger makes writing in Markdown easy because it hides the stuff happening behind the scenes, but it's worth exploring how the process works in general.
When you write in Markdown, the text is stored in a plaintext file that has an
.markdown extension. But then what? How is your Markdown-formatted file converted into HTML or a print-ready document?
The short answer is that you need a Markdown application capable of processing the Markdown file. There are lots of applications available — everything from simple scripts to desktop applications that look like Microsoft Word. Despite their visual differences, all of the applications do the same thing. Like Dillinger, they all convert Markdown-formatted text to HTML so it can be displayed in web browsers.
Markdown applications use something called a Markdown processor (also commonly referred to as a "parser" or an "implementation") to take the Markdown-formatted text and output it to HTML format. At that point, your document can be viewed in a web browser or combined with a style sheet and printed. You can see a visual representation of this process below.
To summarize, this is a four-part process:
From your perspective, the process will vary somewhat depending on the application you use. For example, Dillinger essentially combines steps 1-3 into a single, seamless interface — all you have to do is type in the left pane and the rendered output magically appears in the right pane. But if you use other tools, like a text editor with a static website generator, you'll find that the process is much more visible.
Markdown is a fast and easy way to take notes, create content for a website, and produce print-ready documents.
It doesn't take long to learn the Markdown syntax, and once you know how to use it, you can write using Markdown just about everywhere. Most people use Markdown to create content for the web, but Markdown is good for formatting everything from email messages to grocery lists.
Here are some examples of what you can do with Markdown.
Markdown was designed for the web, so it should come as no surprise that there are plenty of applications specifically designed for creating website content.
If you're looking for the simplest possible way to create a website with Markdown files, check out blot.im and smallvictori.es. After you sign up for one of these services, they create a Dropbox folder on your computer. Just drag and drop your Markdown files into the folder and — poof! — they're on your website. It couldn't be easier.
If you're familiar with HTML, CSS, and version control, check out Jekyll, a popular static site generator that takes Markdown files and builds an HTML website. One advantage to this approach is that GitHub Pages provides free hosting for Jekyll-generated websites. If Jekyll isn't your cup of tea, just pick one of the many other static site generators available.
If you'd like to use a content management system (CMS) to power your website, take a look at Ghost. It's a free and open-source blogging platform with a nice Markdown editor. If you're a WordPress user, you'll be happy to know there's Markdown support for websites hosted on WordPress.com. Self-hosted WordPress sites can use the Jetpack plugin.
Markdown doesn't have all the bells and whistles of word processors like Microsoft Word, but it's good enough for creating basic documents like assignments and letters. You can use a Markdown document authoring application to create and export Markdown-formatted documents to PDF or HTML file format. The PDF part is key, because once you have a PDF document, you can do anything with it — print it, email it, or upload it to a website.
Here are some Markdown document authoring applications I recommend:
In nearly every way, Markdown is the ideal syntax for taking notes. Sadly, Evernote and OneNote, two of the most popular note applications, don't currently support Markdown. The good news is that several other note applications do support Markdown:
If you can't part with Evernote, check out Marxico, a subscription-based Markdown editor for Evernote, or use Markdown Here with the Evernote website.
Looking to self-publish a novel? Try Leanpub, a service that takes your Markdown-formatted files and turns them into an electronic book. Leanpub outputs your book in PDF, EPUB, and MOBI file format. If you'd like to create paperback copies of your book, you can upload the PDF file to another service such as Kindle Direct Publishing. To learn more about writing and self-publishing a book using Markdown, read this blog post.
Believe it or not, you can generate presentations from Markdown-formatted files. Creating presentations in Markdown takes a little getting used to, but once you get the hang of it, it's a lot faster and easier than using an application like PowerPoint or Keynote. Remark (GitHub project) is a popular browser-based Markdown slideshow tool, as is Cleaver (GitHub project). If you use a Mac and would prefer to use an application, check out Deckset or Marked.
If you send a lot of email and you're tired of the formatting controls available on most email provider websites, you'll be happy to learn there's an easy way to write email messages using Markdown. Markdown Here is a free and open-source browser extension that converts Markdown-formatted text into HTML that's ready to send.
Markdown is a natural fit for technical documentation. Companies like GitHub are increasingly switching to Markdown for their documentation — check out their blog post about how they migrated their Markdown-formatted documentation to Jekyll. If you write documentation for a product or service, take a look at these handy tools:
One of the most confusing aspects of using Markdown is that practically every Markdown application implements a slightly different version of Markdown. These variants of Markdown are commonly referred to as flavors. It's your job to master whatever flavor of Markdown your application has implemented.
To wrap your head around the concept of Markdown flavors, it might help to think of them as language dialects. People in Ciudad Juárez speak Spanish just like the people in Barcelona, but there are substantial differences between the dialects used in both cities. The same is true for people using different Markdown applications. Using Dillinger to write with Markdown is a vastly different experience than using Ulysses.
Practically speaking, this means you never know exactly what a company means when they say they support "Markdown." Are they talking about only the basic syntax elements, or all of the basic and extended syntax elements combined, or some arbitrary combination of syntax elements? You won't know until you read the documentation or start using the application.
If you're just starting out, the best advice I can give you is to pick a Markdown application with good Markdown support. That'll go a long way towards maintaining the portability of your Markdown files. You might want to store and use your Markdown files in other applications, and to do that you need to start with an application that provides good support. You can use the tool directory to find an application that fits the bill.
There are lots of resources you can use to learn Markdown. Here are some other introductory resources:
Just like many other apps, Zettlr makes use of
Markdown, originally invented by John Gruber. Of course, over such a long period of time, a huge amount of developments have taken place, that have created the possibilities of modern Markdown applications. In this document the following topics are covered:
Since the personal computer became widely available in the 1990s, there were two groups of formats existing side-by-side: word processor documents, such as
.odt and code documents, such as
For a long time, both these groups of documents stayed as distinct as would their users. Most office-workers only know how to use Microsoft Word or Excel, maybe also LibreOffice-implementations, while close to nobody coming from a STEM-background would voluntarily use Word or similar software. Those scientists have chosen a different path: they developed a programming language called LaTeX, which allows them to create neatly formatted PDF-files from a bunch of code—they follow the same workflow as researchers from the arts and humanities or regular administrative officers, but use different documents for that.
When Markdown was inaugurated by John Gruber in 2004, it was basically like saying: "Why not both?" Markdown combines both the clear reading experience from word processor documents with the benefits of software code documents, which is both versatile and easy to use—even for people that only know how to operate Word or Writer. One small example: While in word processors you would create a heading by typing "some text" and then selecting the
Heading 1 format from some menu, in Markdown you would simply type
# some text, where the hashtag-symbol tells you immediately: "This is a first level heading!"
At first, Markdown was basically a small script John Gruber wrote for himself to yield these benefits, and it contained a lot of inconsistencies and didn't support many different elements. But over the years, progress was made. Two dates are notable:
Today, several implementations of the Markdown syntax coexist. The most noteworthy are:
