Worked on documentation hygiene within the CleverCloud/documentation repository, focusing on improving clarity and consistency for developer onboarding. Addressed heading capitalization in the reference-environment-variables.md file, aligning documentation with established standards and reducing potential confusion for downstream teams. The update was implemented using Markdown, leveraging documentation skills to ensure precise and traceable changes through a single, well-scoped Git commit. This targeted improvement supported easier audit and review processes, while also enhancing the accuracy of environment variable references. The work contributed to faster onboarding and fewer support questions, reflecting a methodical approach to documentation quality and technical communication within the project.
