Worked on a comprehensive documentation overhaul for the hyperledger-iroha/iroha repository, focusing on the Iroha CLI client and main project documentation. The effort centered on reorganizing and refreshing the README files and related docs using Markdown, with an emphasis on improving navigation and clarity for developers. Outdated information was removed to maintain accuracy, and direct links to Iroha 2 CLI usage documentation were added to streamline onboarding. The work prioritized knowledge transfer and documentation governance, resulting in clearer guidance, improved cross-references, and better alignment with Iroha 2 tooling. No bugs were fixed, as the focus remained on documentation quality.
