Code Documentation

There are eight rules that we can follow to produce good documentation:

  1. Write documentation that is inviting and clear
  2. Write documentation that is comprehensive, detailing all aspects of the project
  3. Write documentation that is skimmable
  4. Write documentation that offers examples of how to use the software
  5. Write documentation that has repetition, when useful
  6. Write documentation that is up-to-date
  7. Write documentation that is easy to contribute to
  8. Write documentation that is easy to find


Regarding the code documentation on software engineering, there are few things to know.

The benefits of good documentation are many. Good documentation means it’s easier to…

  • Onboard new developers to a project
  • Track the status of ongoing development
  • Continue work when a developer gets sick or leaves the company
  • Share your work with a client’s development team


Some important things that goes on code documentation are:

Consistently Use the Same Documentation Protocols and Management Tools


The Challenge of Good Documentation

Code documentation is hard. It’s easy to write rules about what to document, and check off the box which says that the code is documented. It’s much harder to provide context to a problem, which is always available and accurate.  We hope this guide helps keep your docs useful and up-to-date.

Some important suggestions

  1. Include A README file that contains
    • A brief description of the project

    • A short example/tutorial
  2. Allow issue tracker for others
    • What a function do
    • What the function’s parameters or arguments are
    • What a function returnsWrite an API documentation
  3. Document your code
  4. Apply coding conventions, such as file organization, comments, naming conventions, programming practices, etc.
  5. Include information for contributors
  6. Include citation information
  7. Include licensing information
  8. Link to your e-mail address at the end
