Worked on improving the documentation for the erlang/otp repository, focusing on enhancing readability and diagram clarity. Addressed issues with garbled tables and refined Mermaid diagrams to provide clearer visual references for users and contributors. Restored bold subsections throughout the documentation to improve navigation and accuracy, making it easier for new developers to onboard and reference material efficiently. All changes were managed and tracked using Git, ensuring traceability and auditability of documentation updates. Utilized Markdown for technical writing and documentation hygiene, aligning the project with open source quality standards and reducing support overhead for the erlang/otp community.
