# Metadata
You can add metadata to your notes by adding a block on the ==first line of your note==. The block must start and end with three hyphens (`---`).
```yaml

Tags show like this: #obsidian/formatting but I usually just stick to putting tags in the frontmatter / metadata.
## Code
Text inside `backticks` on a line will be formatted like code.
Code blocks use three backticks and can add syntax highlighting to a code block, by adding a [language code](https://prismjs.com/#supported-languages) after the first set of backticks.
```md
Text inside `backticks` on a line will be formatted like code.
```
| Syntax Highlighting | Code |

| markdown | md |
| HTML | html |
| CSS | css |
| Javascript | js |
| YAML | yaml |
| Twig | twig |
| BBCode | bbcode |
# Quotes

# Callouts
Callouts can be nested and can contain other content as well.
| Callout | Code | Aliases |
| --- | --- | --- |
| info | `> [!info]` | |
| note | `> [!note]` | |
| TL;DR | `> [!tldr]`| `abstract`, `summary`|
| todo | `> [!todo]`| |
| tip | `> [!tip]` | `hint`, `important`|
| success | `> [!success]` | `check`, `done` |
| question | `> [!question]` | `help`, `faq` |
| warning | `> [!warning]`|`caution`, `attention`|
| failure | `> [!failure]` | `fail`, `missing`|
| danger | `> [!danger]`| `error`|
| bug | `> [!bug]`| |
| example | `> [!example]`|
| quote | `> [!quote]` | `cite`|
> [!info] Info: Change the first line for a custom title
> Add extra content here.
> [!note]- Note
> Add a `-` after the callout to make it collapsible e.g. `[!note]-`
> You can make a callout foldable by adding a plus (+) or a minus (-) directly after the type identifier.
> A plus sign expands the callout by default, and a minus sign collapses it instead.
> [!tldr]+
> This one is expanded by default because it has a `+`
> [!tip]
> [!success]
> [!question]
> [!warning]
> [!failure]
> [!danger]
> [!bug]
> [!example]
> [!quote]
# Lists
Unordered lists use hyphens `-`
- stuff
- things
Ordered lists use number followed by `.`
1. first thingy
2. second thingy
Combinations:
You can press `Tab` or `Shift+Tab` to indent or unindent one of more selected list items.
1. first thingy
- stuff
- things
1. part one
2. part two
## Task Lists
To create a task list, start each list item with a hyphen and space followed by `[ ]`.
```md
- [x] This is a completed task.
- [ ] This is an incomplete task.
```
- [x] This is a completed task.
- [ ] This is an incomplete task.
You can toggle a task in Reading view by selecting the checkbox.

# Horizontal Rule
Three hyphens `---` but not directly below text or it will turn it into a header. Or just use three ~~asteriskes. Asterisk?~~ asterisks `***`. TIL I've been spelling it wrong as *asterix*.
***
# Comments
You can add comments by wrapping text with `%%`. Comments are only visible in Editing view. %%haha you can't see me%%.
```md
This is an %%inline%% comment.
%%
This is a block comment.
Block comments can span multiple lines.
%%
```

## Tweets

# Footnotes
You can add footnotes[^1] to your notes using the following syntax:
```md
This is a simple footnote[^1].
[^1]: This is the referenced text.
[^2]: Add 2 spaces at the start of each new line.
This lets you write footnotes that span multiple lines.
[^note]: Named footnotes still appears as numbers, but can make it easier to identify and link references.
```
You can also inline footnotes in a sentence. Note that the caret goes outside the brackets.
```md
You can also use inline footnotes. ^[This is an inline footnote.]
```
