Worked on improving the developer documentation for the tact-lang/mintlify-ton-docs repository, focusing on aligning guidance with the evolving TON Rust SDK ecosystem. Updated Markdown-based documentation to promote ton-rs as the recommended SDK while clearly deprecating tonlib-rs, helping developers transition smoothly to supported tooling. The approach emphasized clarity and reduced friction by consolidating deprecation messaging and linking relevant artifacts to the changes. No bug fixes were required during this period, as the work centered on documentation quality and accuracy. Demonstrated skills in technical writing, documentation management, and Markdown, ensuring the repository reflects the current state of TON SDK development.
