Markdown is a plain-text format for writing structured documents without wrestling toolbars. Developers use it on GitHub, Notion imports it, static site generators (Hugo, Jekyll, Astro) thrive on it, and support teams publish help centers from .md files. You can write Markdown in any text editor; the skill is learning a small syntax vocabulary and knowing how to migrate existing Word or HTML content into it.

Headings and paragraphs

Headings use hash symbols. One hash is top-level; more hashes mean smaller sections. Separate paragraphs with a blank line—single line breaks do not create new paragraphs in most parsers unless you end a line with two spaces or use HTML <br>.

# Title
## Section
### Subsection

Paragraph one.

Paragraph two.

Emphasis and lists

Bold wraps with double asterisks: **bold**. Italic uses single asterisks: *italic*. Unordered lists start with - or *; ordered lists use 1. numbering. Nested items indent with two spaces.

Numbered steps suit instructions: 1. Install, 2. Configure, 3. Deploy.

Links, images, and code

Links: [label](https://example.com). Images: ![alt text](image.png). Inline code uses backticks: `npm install`. Fenced code blocks use triple backticks with an optional language tag for syntax highlighting:

```js
console.log('Hello');
```

Tables and blockquotes

GitHub-flavored Markdown (GFM) adds tables with pipes and header separators:

| Tool | Format |
| ---- | ------ |
| DOCX | .docx  |

Blockquotes begin with > for callouts or email excerpts. Horizontal rules are three dashes --- on their own line.

Why teams adopt Markdown

Plain text diffs cleanly in Git—reviewers see exactly what changed. No proprietary binary blobs. Writers focus on structure; designers apply CSS at publish time. For API docs, changelogs, and README files, Markdown is the default lingua franca. The limitation is complex page layout: multi-column magazines still belong in InDesign or Word until export.

Converting Word (DOCX) to Markdown

Most organizations have years of .docx specs, policies, and meeting notes. Manual copy-paste mangles lists and headings. Automated converters map Word styles to # headings, turn bullet lists into - items, and download embedded images. Expect to skim output: custom Word templates, text boxes, and floating figures may need hand correction. Start from consistently styled documents (Heading 1, Heading 2, Normal) for best results.

Converting HTML to Markdown

Scraped help articles, exported CMS pages, and email templates often arrive as HTML. Converters strip tags and emit Markdown equivalents—<h2> becomes ##, anchors become link syntax, <pre> becomes fenced code. Messy inline styles and nested tables are the hardest; simplify HTML before conversion when possible.

Version control and review habits

Store Markdown in Git with meaningful commit messages (“update refund policy FAQ”). Pull requests show line-level diffs—legal and product teams can review without opening Word. Pair Markdown repos with CI that builds preview sites on every branch so stakeholders approve rendered HTML, not raw syntax.

When mixing Markdown with automated tools, pin a style guide: Oxford comma or not, product name capitalization, and locale-specific spelling. Linters like markdownlint catch trailing spaces and inconsistent heading jumps that break table-of-contents generators.

Convert documents to Markdown

Free browser tools—paste HTML or upload DOCX and download clean .md files.

Editing and preview tools

VS Code, Obsidian, Typora, and StackEdit offer live preview. Store docs in a repo with folders per product area. Use consistent filenames (billing-faq.md) and a short CONTRIBUTING guide so headings match your site’s table of contents component.

Markdown rewards consistency more than memorizing every extension—tables, task lists - [ ], footnotes vary by platform. Master the core syntax, automate imports from Word and HTML, and your documentation becomes portable, searchable, and ready for the web.
