To translate developer documentation written as docs-as-code, translate only the prose while protecting code blocks, inline code, link URLs, and front matter, so the Markdown still renders and the examples still run. Bluente is an AI-powered document translation platform used by 30,000+ professionals to translate files in 120+ languages while preserving the original formatting, which is the same principle docs-as-code needs: change the words, leave the structure untouched.
Translated documentation that breaks rendering, mangles a code sample, or rewrites a URL is worse than no translation, because it actively misleads developers. This guide covers how to localize Markdown-based docs, MkDocs, Docusaurus, READMEs, API references, without introducing those failures.
What Is Docs-as-Code and Why Is It Hard to Translate?
Docs-as-code is the practice of writing documentation in plain-text formats like Markdown, storing it in Git, and building it with tools such as MkDocs or Docusaurus, the same way you ship software. It is hard to translate because a Markdown file mixes human prose with machine-critical syntax, and a naive translator treats them the same.
The danger spots are specific: code fences and inline code must stay byte-for-byte identical, link targets and anchors must not change, front matter keys must remain in English even when their values are translated, and heading slugs feed navigation. Translate any of those by accident and you break the build or send a reader to a 404. The fix is a translator that understands what to leave alone.
How Do You Translate a Markdown File Without Breaking It?
You translate a Markdown file safely by isolating and protecting code fences, inline code, URLs, image paths, and front matter, then translating only the surrounding prose, so the document renders identically with localized text. The translated file should differ from the source in nothing but the human-readable language.
This is the same job Bluente does for any structured document: preserve the scaffolding, translate the content. For documentation teams, that means a README, a getting-started guide, or a contributing doc can be translated across 120+ languages in under two minutes on average without a developer having to hand-verify that every backtick survived. Protected terms, product names, API method names, CLI commands, stay exactly as written.
How Do MkDocs and Docusaurus Handle Translation?
MkDocs and Docusaurus differ in how much they localize out of the box: Docusaurus has built-in i18n that lets you translate content and deploy each language as its own site, while MkDocs translates only theme labels by default, so the Markdown body of a page needs a separate translation step. Knowing which you run determines where the translation happens.
In both cases the actual page content, the prose a developer reads, still has to be translated by something, and that something has to respect Markdown and MDX syntax. Whether you keep translated files in Git alongside the source or generate them in your build, the requirement is the same: the localized Markdown must render cleanly and keep every code sample runnable. Feeding the files through a format-preserving translator and committing the results fits the docs-as-code model directly.
Can You Translate API References and OpenAPI Specs?
Yes, with care: translate the human-readable descriptions, summaries, and parameter explanations while leaving endpoint paths, field names, enums, and example values untouched. An API reference is a contract, and translating a field name or an example value silently breaks the developers relying on it.
The same protect-the-machine-parts rule that governs Markdown governs API docs. Descriptions and guidance get localized so a developer reading in their own language understands the intent; the structural identifiers stay constant so the documentation still matches the running API. Bluente's glossary and protected-term handling are built for this distinction, keeping technical identifiers fixed while the explanatory prose is translated. Bluente's own API is documented at https://bluente.com/docs.
How Do You Keep Terminology Consistent Across a Doc Set?
You keep terminology consistent by locking product names, feature names, and technical terms in a custom glossary that applies to every file in the documentation set, so the same concept is named the same way across the README, the guides, the API reference, and the changelog. Drift between these surfaces is a frequent source of confusion in localized docs.
Bluente applies one glossary across Markdown and the other formats documentation travels in, such as PDF exports and DOCX, so a developer moving between a web guide and a downloaded PDF sees consistent terminology. As of June 2026, with docs-as-code and AI agents both consuming documentation programmatically, this consistency also improves how reliably automated tools parse your localized content.
Is It Secure for Internal and Pre-Release Docs?
Yes. Bluente runs with zero data retention, automatic deletion within 24 hours, and end-to-end encryption, and nothing you translate is used to train any AI model. The platform holds SOC 2 Type II, GDPR, and ISO 27001 compliance.
Internal runbooks, pre-release API docs, and architecture guides often describe systems you have not shipped or disclosed, so a translation step that retains or trains on them is a real exposure. A no-retention, encrypted workflow lets engineering and DevRel teams localize sensitive documentation without leaking it.
Frequently Asked Questions
Q: Will translation break my code blocks or inline code? No, if you use a translator that protects code fences and inline code. The prose around the code is translated while the code itself stays byte-for-byte identical, so examples still run and the Markdown still renders.
Q: Are links and front matter safe? Yes. Link URLs, image paths, and front matter keys are preserved so navigation and the build are not broken; only human-readable values, such as a front matter title, are translated.
Q: Does this work with MkDocs and Docusaurus? Yes. Docusaurus localizes content natively and MkDocs needs a separate step for page content, but in both cases the Markdown body must be translated by a tool that respects the syntax, then committed or built in the normal docs-as-code flow.
Q: Can I translate an OpenAPI spec? Yes, by translating descriptions and summaries while leaving paths, field names, enums, and example values untouched, so the documentation still matches the live API.
Q: How do I stop product and API names from being translated? Add them to a custom glossary as protected terms. They will stay exactly as written across every file while the surrounding prose is localized.
Q: How many languages and how fast? Bluente supports 120+ languages and translates most files in under two minutes on average, fast enough to localize a documentation set as part of a release.
