Spacehall markdown formatting reference

Headings

To create a heading, add one to six # symbols before your heading text. The number of # you use will determine the hierarchy level and typeface size of the heading.

# A first-level heading
## A second-level heading
### A third-level heading

Styling text

You can indicate emphasis with bold, italic, strikethrough, subscript, or superscript text.

Quoting text

You can quote text with a >.

Text that is not a quote

> Text that is a quote

Quoted text is indented.

Quoting code

You can call out code or a command within a sentence with single backticks. The text within the backticks will not be formatted.

Use `cat file.txt` to output the content of the text file.

To format code into its own distinct block, use triple backticks.

Print a text string:

```
print("Hello World!")
```

Spacehall will try to infer the programming language from the block's content.

You can also set it manually by adding the language name after the first backticks.

Print a text string:

```rust
println!("Hello World!")
```

You can create an inline link by wrapping link text in brackets [ ], and then wrapping the URL in parentheses ( ).

This discussion is hosted on [Spacehall](https://spacehall.app).

Valid URLs are automatically transformed as links.

Images

You can display an image by adding ! and wrapping the alt text in [ ].

Alt text is a short text equivalent of the information in the image.

Then, wrap the link for the image in parentheses ().

![My screenshot](https://some-url.com/my-screenshot.jpg)

To order your list, precede each line with a number.

Nested Lists

You can create a nested list by indenting one or more list items below another item.

1. First list item
   - First nested list item
     - Second nested list item

Task lists

You can create a task list by preceding one or more line with - [ ] for new tasks, and - [x] for completed tasks.
