Headings & Structure

Organize your document hierarchy with predictable heading levels and blockquotes.

`Heading level 1 ===================`	Setext H1	Alternative underline style for H1 and H2.
`> Quoted insight`	Blockquote	Add nested > symbols for multi-level quotes.

Markdown	Preview	Notes
`bold`	bold	Use ** or __ for strong emphasis.
`italic`	italic	Use * or _ for emphasis.
`~~strikethrough~~`	strikethrough	Great for edits or completed tasks.
`inline code`	`inline code`	Wrap code with single backticks.

Lists, Tasks & Breaks

Structure ideas with ordered lists, checklists, and horizontal rules.

Markdown	Preview	Notes
`- unordered item`	unordered item	Use -, +, or * for unordered lists.
`1. ordered item`	ordered item	Numbers auto-increment even if repeated.
`- [x] Completed task`	Completed task	GitHub Flavored Markdown supports task lists.
`--- or ***`		Create thematic breaks with three hyphens or more.

Links, Media & Code Fences

Embed rich references, images, and syntax-highlighted blocks.

Markdown	Preview	Notes
`[ToolHop](https://toolhop.app)`	ToolHop	[text](url) is the classic inline link pattern.
`![Alt text](graphic.png)`	Image with alt text	Same format as links but prefixed with !.
`[id]: https://example.com`	Reference-style links keep paragraphs tidy.	Use [link text][id] inline, define at the bottom.
```js console.log('hi') ```	Multi-line fenced code block	Fence triple backticks and add a language tag for syntax highlighting.

Tables & Advanced Blocks

Create tabular data and sprinkle raw HTML for extra control.

Markdown	Preview	Notes
`\| Col \| Col \|`	\| Col \| Col \|	Use pipes and --- separators. Align with :---, :---:, or ---:.
`:---`	Left align	:--- for left, :---: center, ---: right alignment.
```mermaid```	Mermaid diagram	Platforms like GitHub render diagrams when enabled.
`<details><summary>Title</summary>Hidden</details>`	Expandable details	Raw HTML is allowed when Markdown falls short.

Best Practices

Quick reminders for professional documentation.

Readable line length
Wrap paragraphs around 80 characters so diffs stay small.
Consistent spacing
Leave one blank line between headings, lists, and paragraphs for reliable rendering.
Use reference links
Collect all outbound URLs at the bottom of long documents for easier editing.
Annotate code fences
Language hints (```js, ```bash) unlock syntax highlighting across most renderers.
