Our small product and engineering team ships updates several times a week, and keeping technical documentation current is becoming increasingly difficult. Code changes have a well-established review process, but documentation is easy to overlook. A feature may launch or an API may change, only for someone to discover weeks later that an example or reference page is outdated. For teams working at a similar release pace, what processes or tools have helped keep documentation updates consistent and reduce drift?

The most reliable approach is to make documentation impact part of the release checklist. If an API, configuration option, or user-facing behavior changes, the related documentation should be updated and reviewed in the same pull request or ticket. That keeps docs visible during development instead of turning them into post-release cleanup.
We include documentation in the deployment and release process so it stays visible and connected to the change. Keeping the source docs alongside the code makes updates easier to include in the same review, and automated checks can catch broken links or stale examples. Tools can reduce the scavenger hunt, but someone still needs clear ownership of the content.
I’ve seen tools that provide drift checks and hosted docs. I’m considering that kind of setup, but the workflow and ownership piece seems just as important.
A lightweight rule in the repository can help too: whenever a change affects documented behavior, the contributor must update the corresponding docs before merging. Some teams encode that rule in contributor instructions or automation for their documentation build. It will not catch every omission, but it makes the expected workflow explicit and prevents documentation from becoming a completely separate task.
Treat documentation like code during review. For any change involving an API, configuration, runbook, or screenshots, reviewers can ask which documentation needs updating just as they would ask about tests. It also helps to keep the docs in the same repository as the code, since a separate wiki often has unclear ownership and is easy to forget.
That makes sense. Keeping the docs work attached to the change should also prevent a huge backlog of outdated pages from building up.
