A Markdown preview workflow for clear, portable documentation

Write the purpose of the document in the first paragraph, then create headings for the questions or actions that follow. A setup guide might use Requirements, Installation, First Run, and Troubleshooting. A project note may need Context, Decision, and Follow-up. This structure is more useful than adding headings simply to create more visual breaks or repeat a target phrase.

Keep one main title and use lower-level headings for the sections beneath it. Previewing makes the hierarchy visible, but the source is where you verify that the number of hash characters is consistent. A reader should be able to scan the page and understand its sequence before reading every detail.

Use numbered lists when order matters and bullets when it does not. For a procedure, start each step with a verb and include the result a reader should see. Preview the list with both short and long steps because wrapping can make a multi-line item look like a new step if the indentation is wrong. Keep related notes inside the same item when they depend on that action.

If a list contains commands, put the command in a code span or fenced code block and explain what it does in normal prose. The preview should show a clear boundary between something the reader can copy and the explanation that tells them when to use it. This separation also reduces the chance that a command is edited accidentally while the document is being read.

Link text should describe the destination. 'Read the deployment checklist' is more useful than 'click here', especially when someone scans a list of links or uses assistive technology. Open each important link and confirm that it points to the intended version, repository, or policy page. A valid Markdown link can still be a poor link if its wording does not explain why the reader should follow it.

For tables, include only information that benefits from side-by-side comparison. Check the alignment row, a long cell, an empty cell, and punctuation inside a value. On narrow screens, a table may be harder to read than a set of labeled paragraphs. If the preview shows horizontal overflow, simplify the table instead of asking readers to drag across a wall of text.

Use fenced code blocks for multi-line commands, JSON, logs, or source code. Add a language label when the destination supports highlighting, but remember that highlighting is presentation only. A Markdown previewer should never execute the code in your document. Read the example as if you were the person who will copy it and check that the required values are obvious.

Escape asterisks, underscores, angle brackets, and backticks when they should appear literally. File names and technical identifiers often contain characters that Markdown treats as formatting. Previewing the result catches a word that accidentally became italic, a URL that was cut by punctuation, or an example that disappeared into an unintended tag.

A previewer can show a clean rendering while the final platform uses a different Markdown dialect. GitHub, a chat tool, a documentation generator, and a CMS may support different extensions or sanitize HTML differently. Copy a small representative section into the real destination before publishing the whole document. Compare headings, tables, code blocks, links, and any embedded content.

The TextRepeat.org previewer processes the draft in your browser, so you can check a document without creating an account or uploading it to a TextRepeat.org server. Use an approved environment for confidential material when your organization requires one. When the document is ready, keep the source in version control or another durable location so the rendered copy can be regenerated after an edit.

Before publishing, do one plain-text pass as well. A reader may copy a command, a link, or a table cell into another application where formatting disappears. Make sure the wording still makes sense without color, syntax highlighting, or a particular theme. The preview is a visual check, while the source and plain text remain the durable forms of the document.

A final mobile check is worthwhile because narrow screens expose long headings, wide tables, and code lines that look comfortable on desktop. Shorten a heading, split a table, or add a paragraph break when the reader has to scroll sideways to understand the point.
