Docs-as-Code: Keeping Documentation Close to Your Code

Docs-as-code is the practice of writing documentation in the same plain-text formats and workflows you already use for source code: Markdown files, version control, pull requests, and code review.

Why it works

• Versioned — docs live alongside the code they describe, so a change to behavior and a change to its documentation can land in the same commit.
• Reviewable — a documentation change goes through the same review process as everything else, instead of getting lost in a separate wiki.
• Diffable — plain text means you can see exactly what changed between two versions, the same way you'd read a code diff.

Where a Markdown editor fits in

Most docs-as-code workflows still involve writing and previewing Markdown outside of the terminal — checking that a table renders correctly, that a diagram compiles, that headings produce a sane table of contents. That's the gap MDViewerOnline fills: a live preview for the Markdown you're about to commit, without needing a local build tool set up just to check formatting.

Getting started

You don't need special tooling to adopt docs-as-code. Start by moving your existing documentation into Markdown files inside the same repository as your project, and review changes to them the same way you review code.
