Contributed to the Scalingo/documentation repository by updating the MySQL Primary Key Requirement documentation to reflect new constraints in MySQL 8 and above. Focused on improving documentation accuracy, the work involved revising Markdown files to mandate primary keys for MySQL 8+, providing a clear example SQL statement for adding a primary key, and updating the modification date to ensure traceability. This documentation update helps users understand integration requirements and reduces onboarding friction for those upgrading databases. The approach emphasized clarity and maintainability, leveraging skills in technical writing and Markdown to align documentation with evolving MySQL standards and customer needs.
