Simon Maresz developed a feature for the apify/actor-templates repository that enhances template integrity by detecting modifications in template README files. He introduced an HTML comment marker to each README, enabling automated identification of original versus altered documentation. To ensure consistency, Simon implemented tests that verify the presence of this marker in all new templates, laying the foundation for future CI-based validation and automation. His work focused on documentation, template development, and testing, utilizing TypeScript and JavaScript to integrate these changes. This targeted approach addressed the risk of unnoticed README changes and improved maintainability across the Apify template ecosystem.
