Good technical documentation helps a new developer operate and change a system without depending entirely on the original author. It should describe verified procedures and responsibilities rather than simply listing technologies.
Document the tasks a successor will need to perform
Cover local setup, building, deployment, configuration and recovery. Explain integrations and the business rules that are easy to miss. Keep credentials in an appropriate secure store; documentation should explain how authorised access is obtained without exposing secrets.
Practical checks
- An application and infrastructure overview.
- Repository locations and environment requirements.
- Release, backup and recovery procedures.
- Known limitations, dependencies and outstanding work.
Questions and answers
How can we check whether the documentation is useful?
Ask an authorised developer unfamiliar with the system to follow a setup or deployment exercise in a suitable environment. Record gaps and correct them.
Does documentation need ongoing maintenance?
Yes. Update it alongside changes to hosting, releases and integrations. Assign responsibility so the handover information does not become outdated immediately.
