# Overview of TON whitepapers (https://docs-rbcpr9qys-ton-core-docs.vercel.app/llms/foundations/whitepapers/overview/content.md)



The original TON documentation was written by Dr. Nikolai Durov and comprises a series of whitepapers. They provided a comprehensive overview of all aspects of TON.

While most of the information described in the original PDFs holds some truth, those whitepapers are considered legacy due to a lack of updates and gradual integration of their contents into actual documentation pages. Notice that "legacy" here does not mean "outdated", but rather less kept up to date compared to the regular pages.

Only an English PDF version of whitepapers is considered "official." English HTML version is provided by documentation team. The rest are community translations.
