Worked on improving the documentation quality for the Open-Pix/openpix-developers repository by addressing a terminology inconsistency in the refunds API section. Focused on correcting the Portuguese term from "Extorno" to "Estorno" throughout the resources.md file, ensuring that the language aligns with standard refunds terminology. This change aimed to enhance clarity for both developers and support teams, reducing potential confusion during onboarding and support interactions. Utilized Markdown for precise documentation updates and applied strong attention to detail in maintaining a clear, traceable commit history. The work emphasized documentation skills and contributed to more accurate and accessible API reference materials.
