CTF Write-Up Template

Writing a clear and well-structured CTF write-up is one of the best ways to improve your skills and contribute
to the cybersecurity community. For newcomers, the process can feel a bit unclear at first—what should you
document, how detailed should it be, and how do others typically format their solutions?
This guide breaks down a simple, consistent structure you can follow for any challenge. It helps you capture your
thought process, document the tools and steps you used, and present your solution in a way that’s helpful both for
yourself later on and for others learning from your work.

Template Structure

  • Template Header. Use the following YAML preamble at the top of your write-up to provide metadata about the challenge
    for the website to display correctly. This includes the title, date, description, tags, and categories. Adjust the
    fields as needed for each write-up and fill in the placeholders with the appropriate information for each challenge.
