15## Headings
16Headings are created by adding one or more `#` symbols before your heading text. The number of `#` you use will determine the size of the heading.
17
18```rust
19gpui::window::ViewContext
20impl<'a, V> ViewContext<'a, V>
21pub fn on_blur(&mut self, handle: &FocusHandle, listener: impl FnMut(&mut V, &mut iewContext<V>) + 'static) -> Subscription
22where
23 // Bounds from impl:
24 V: 'static,
25```
26
27## Emphasis
28Emphasis can be added with italics or bold. *This text will be italic*. _This will also be italic_
29
30## Lists
31
32### Unordered Lists
33Unordered lists use asterisks `*`, plus `+`, or minus `-` as list markers.
34
35* Item 1
36* Item 2
37 * Item 2a
38 * Item 2b
39
40### Ordered Lists
41Ordered lists use numbers followed by a period.
42
431. Item 1
442. Item 2
453. Item 3
46 1. Item 3a
47 2. Item 3b
48
49## Links
50Links are created using the format [http://zed.dev](https://zed.dev).
51
52They can also be detected automatically, for example https://zed.dev/blog.
53
54## Images
55Images are like links, but with an exclamation mark `!` in front.
56
57```todo!
58
59```
60
61## Code
62Inline `code` can be wrapped with backticks `` ` ``.
63
64```markdown
65Inline `code` has `back-ticks around` it.
66```
67
68Code blocks can be created by indenting lines by four spaces or with triple backticks ```.
69
70```javascript
71function test() {
72 console.log("notice the blank line before this function?");
73}
74```
75
76## Blockquotes
77Blockquotes are created with `>`.
78
79> This is a blockquote.
80
81## Horizontal Rules
82Horizontal rules are created using three or more asterisks `***`, dashes `---`, or underscores `___`.
83
84## Line breaks
85This is a
86\
87line break!

91Remember, markdown processors may have slight differences and extensions, so always refer to the specific documentation or guides relevant to your platform or editor for the best practices and additional features.
