What Read the Docs is

Read the Docs is a documentation building and hosting platform for technical projects. On Read the Docs, developers and documentation teams can connect source repositories, build documentation on commits, publish versioned docs, use integrated search, preview pull requests, and manage public or private documentation workflows.

Documentation hosting

The platform takes documentation source files and turns them into hosted websites. It is commonly used by open-source software projects, Python libraries, developer tools, internal engineering teams, and products that need reliable versioned documentation.

Builds and versions

Read the Docs can build documentation from repository changes and publish different versions, such as stable, latest, release branches, or pull request previews. This matters because users often need docs that match the exact software version they are using.

Search and discoverability

Good documentation needs to be findable. Read the Docs provides hosted pages, search features, navigation, canonical URLs, redirects, and project-level organization so users can move from a question to the right page quickly.

Open source and business hosting

Read the Docs supports open-source documentation hosting and also offers business hosting for private or commercial documentation needs. Its funding model combines paid customers and advertising to help sustain the service.

Why it matters

Read the Docs matters because documentation is part of software infrastructure. A project can have excellent code and still fail users if installation guides, API references, tutorials, and release notes are hard to build, host, search, or keep current.

Limits and cautions

Read the Docs hosts and builds documentation, but the quality of the content still depends on each project. Users should check the project owner, selected version, last build date, source repository, and whether the docs match the package or product they are actually using.

Versioned docsDocumentation published for specific releases, branches, or revisions of a project.
Pull request previewA temporary documentation build that lets reviewers inspect changes before they are merged.

Website features

HostingPublish generated documentation websites for software projects and technical teams.
AutomationBuild documentation from repository changes, configuration files, and project versions.
SearchProvide search and navigation so users can find the right page inside a documentation project.

Common misconceptions

Not the documentation authorRead the Docs hosts and builds docs, but the project maintainers write and maintain the content.
Version mattersA documentation page may refer to a different release than the software version someone has installed.
Hosting does not guarantee accuracyA docs site can be hosted well while still containing outdated, incomplete, or project-specific guidance.
