Convert GitHub README to Interactive Docs Site

The approaches, by where content lives

Static site generators build a site from Markdown files in your repository. Content lives beside the code, changes go through pull requests, and versioning comes free because the docs are versioned with the code.

Hosted documentation platforms provide an editor and hosting. Content lives in their system, non-engineers can contribute easily, and it drifts from the code unless someone actively keeps it in step.

Generated-from-source tools build reference material from code comments and type signatures. Always accurate about signatures, and silent about everything else.

Docs in the repository stay current; docs elsewhere do not

This is the single most reliable predictor of whether documentation stays accurate, and it is worth weighting heavily.

When documentation lives beside the code, a change to behaviour and a change to its description arrive in the same pull request and get reviewed together. When it lives in another system, updating it is a separate task that competes with everything else — and loses.

The counter-argument is real: repository-based docs exclude contributors who do not use Git. If your documentation is written by people outside engineering, that is a genuine cost, and a hosted platform may be the right trade.

Generated reference is not documentation

Extracting signatures and comments from source produces an accurate API reference. It does not produce documentation, and conflating the two is a common and expensive mistake.

What is missing is everything a reader actually needs first: what this is for, how to get started, how the pieces fit together, why it works the way it does, and what to do when something goes wrong.

Generated reference answers "what are the parameters of this function". It cannot answer "how do I do the thing I came here for", and that is the question most visitors arrive with.

What a docs site actually needs

Ordered by how often their absence causes a reader to give up.

A getting-started path that works end to end, tested by someone who has not seen the project. Search that returns useful results. Examples that can be copied and run without modification. And a clear statement of which version the documentation describes.

Search is the most under-invested of these. Past a modest size, readers navigate documentation by searching rather than browsing, and a site whose search does not work is functionally a set of disconnected pages.

• A working quickstart — tested by someone new, end to end, recently.
• Search that works — past a certain size this is how people navigate.
• Runnable examples — copy-pasteable without editing to make them work.
• Versioning — which version does this page describe?

The maintenance question decides it

Before choosing anything, answer: who writes this, and when.

If engineers write documentation as part of shipping, put it in the repository and use a static generator. The workflow already matches.

If a technical writer or a product person maintains it, a hosted platform will get more updates than a Git-based one, and more updates matters more than architectural purity.

If nobody has been assigned, the tool choice is irrelevant — you will have a beautiful docs site that is wrong within two releases. That is the failure mode worth designing against.

Where generation helps

The barrier to a docs site is usually not the content but the surrounding work: getting something presentable standing up, and making a README into a navigable site.

Automating that first step is genuinely useful, because a docs site that exists gets improved and one that is planned does not.

What it does not do is write the explanations. The quickstart, the conceptual overview and the troubleshooting section have to come from people who know why the thing works the way it does.
