`solidity-docgen` is a documentation generator for Solidity projects that extracts information from source code and outputs it in customizable Markdown format using Handlebars templates. It's designed for Solidity developers who want to automatically generate documentation for their smart contracts and integrate it with static site generators like Vuepress or MkDocs. The tool can be used as a Hardhat plugin or as a standalone library, accepting Solidity compiler output to produce comprehensive documentation.
