Worked on the PrestaShop/PrestaShop repository to enhance Docker deployment security and maintainability by updating default admin credentials in the docker-compose.yml file and aligning documentation in the README. Focused on enabling environment-variable-based customization, the changes aimed to reduce configuration drift and improve deployment reproducibility for operators. Utilized YAML for configuration management and Markdown for documentation updates, ensuring that deployment guidance remained consistent and clear across the repository. The work emphasized configuration best practices and auditability, with descriptive commit messages supporting future maintenance. No bugs were addressed during this period, as the primary focus was on feature development and documentation alignment.
