Document existing software
When taking over older software, clear explanations are often scarce. Module-by-module drafts give you a starting point to check against the code.

Editorial summary of the source.
What the source shows
Aburok reports module-by-module drafts followed by corrections.
What remains open
Anonymous client project; statements need checking against the code.
OUR ASSESSMENT
Who could this suit?
You are taking over an established application and need reliable orientation.
Prerequisites
Repository access and knowledge of the application.
Your checkpoint
Verify technical statements, add business context and maintain documentation as code changes.
Effort and data
Development skills
Check model access, data processing and maintenance needs for your setup. Complete operating costs remain open in the source.
A closer look at the example
Fictional example for illustration
An older module calculates shipping costs. Source code and tests exist, but readable documentation is scarce.
Draft outline: inputs · calculation rules · dependencies · edge cases. Review each statement against code and tests.
