Developed a comprehensive Q&A covering programming concepts such as polymorphism, immutability, encapsulation, and SOLID principles, using Markdown for clear and accessible guidance. Configured Maven by adding a pom.xml and relevant commands, standardizing the build process and facilitating project setup. Enhanced onboarding by including IDE configuration files and expanding the README, making it easier for new contributors to get started.
