Worked on the bitcoin/bitcoin repository to enhance cross-platform build documentation, focusing on improving clarity and accuracy for developers building Bitcoin Core on NetBSD and macOS. Updated the build guidance by correcting references to autotools and addressing a SQLite typo, ensuring that instructions are both current and accessible. Emphasized technical writing and documentation skills, using Markdown to deliver clear, actionable guidance that reduces build friction and streamlines onboarding for new contributors. No bugs were fixed during this period, as the primary goal was to improve documentation quality and reduce support queries, ultimately contributing to more reliable and maintainable cross-platform builds.
