The idea of markdown is that you write plain text with some additional markup that even without further processing (like rendering it to HTML, or [[Live Preview]]) you could just read and understand. It was inspired by conventions used in plain-text e-mails, before e-mail supported rich formatting.
To write markdown, you just write text. But then to emphasize something you can add `_underscores_` around a phrase to make look _italic_, or `**asterisks**` to make it **bold**. You can also use `~~tildes~~` for ~~strikethrough~~ and `==double equals==` for ==highlighting==.
To add external links you use the `[site link](https://silverbullet.md)` syntax, which will appear as [site link](https://silverbullet.md). If you want to link to other pages in your space you use the `[[wiki link syntax]]`, e.g. [[SilverBullet]]. To change the link text you can use the `[[SilverBullet|best PKM evah]]` syntax: [[SilverBullet|best PKM evah]].
SilverBullet also supports a variant of the unordered list item to define task. Tasks are defined using the `* [ ] Task name` syntax:
* [ ] This is a task
* [ ] And this is another
When you click the checkbox, it will toggle its state and replace the ` ` inside the box with `x`. SilverBullet also supports custom task statuses by putting text in between `[` and `]`. When you click on such custom task states, it will cycle through all the task states it’s seen in your space:
Markdown supports various levels of headings, which generally are created by prefixing a line with one or more `#`. The more `#`‘s the deeper the header nesting.
For the programmers among us, there are three ways to mark up code. If you want to write some code inline, you can use backticks: `this is code`. For long code snippets, you can either use a four-space indent:
