Template example. Not a published community contribution.
Give your generator constraints.
A technical writing template about procedural terrain, useful limits and repeatable experiments.

Define what must remain playable
A terrain generator is not useful just because it produces varied shapes. This example begins with the constraints that matter to the game: connected routes, reachable spaces and readable landmarks.
Separate generation from validation
Describe the generator first, then the checks that reject unsuitable results. Keep the seed and configuration with each test so the experiment can be repeated.
Show the failures
Include a result that did not work and explain why. This helps readers understand the design space rather than only the successful output.
Write your own conclusion
Replace this template with actual inputs, outputs and observations. The illustration is conceptual, not a screenshot from a completed project.
