Documentation Manual

By Olivier Carrère, technical writer · Opinion Blog ↗

This site is the technical manual: a practical guide to the docs-as-code process, from project definition to delivery. The companion blog publishes in-depth essays, analysis, and opinion.

Whether you're choosing between DITA XML and Markdown, migrating to a docs-as-code workflow, or integrating documentation into a CI/CD pipeline — these guides cover the methods, formats, and tools that make technical documentation a sustainable, scalable engineering practice.

A practical path through technical documentation

New to the site or re-evaluating your documentation architecture? Follow this curated sequential path:

The three levels of technical documentationLocate where your organization's documentation practice sits today — from ad-hoc drafting to structured DITA.

Structured and unstructured formatsThe foundational format choice that determines everything downstream: content reuse, translation cost, and tooling.

Case study: NuFirewall documentationStructured authoring in production — a detailed look at the DITA XML techniques that earned press-validated documentation.

Integrating documentation into developmentTreating documentation like code: aligning release cadence, version control, automated testing, and CI/CD pipelines.

Technical writing: an industrial process

How to approach technical writing as an engineering discipline - from project definition to version control, automated testing, quality validation, and delivery.

Project definitionDefine audience, scope, and deliverables before writing - five project parameters every technical writing engagement needs.

Integrating documentation into developmentTreat docs like code: same release cadence, same version control, same review process.

Git: from file to contentGit stores content blobs, not filenames - understanding that model makes branching and diffing documentation much simpler.

Structured DITA XML format

How structured and unstructured documentation differ - topic-based authoring, single-sourcing, and modular document architecture without vendor lock-in.

Case study: NuFirewall documentationPress reviewers cited the documentation as a product strength, not a supplement. A detailed look at the DITA XML techniques that made it possible.

Structured and unstructured formatsDITA's three topic types - concept, task, reference - enforce structure that makes content reusable, translatable, and consistent.

From document to modular document baseReplace monolithic manuals with reusable topic modules: lower translation costs, parallel reviews, multiple output formats from one source pool.

The business case for structured documentation

Why documentation architecture matters to an organization - maturity models, long-term maintenance costs, and technical communication economics.

From technical writing to technical communicationTechnical communication starts before the sale - why the role spans marketing, journalism, and product documentation.

The three levels of technical documentationA three-tier maturity model - wasteland, topic-based, structured DITA - to locate where your organization sits and what the next level costs.

Formats and toolsChoose your source format before your tool - the format determines vendor lock-in, automation options, and long-term costs.
