Worked on enhancing the sandbox documentation within the flipperdevices/u-boot repository, focusing exclusively on improving clarity and accuracy without introducing any functional changes. The approach centered on correcting typographical errors and refining language in RST files, ensuring that onboarding materials are easier to follow and reducing the likelihood of future maintenance issues. By maintaining strict separation between documentation and code, the work preserved build and runtime stability. The improvements leveraged documentation best practices and standardized commit messaging, resulting in clearer guidelines for sandbox usage. This effort contributed to a more accessible developer experience and streamlined future updates to project documentation.
