+## Deprecation of C++ SeedTool
+
+This repo contains the original SeedTool written in C++, and is now deprecated. The [new SeedTool is written in Rust](https://github.com/BlockchainCommons/seedtool-cli-rust) and is a complete rewrite. The new SeedTool's inputs and outputs are compatible with the old SeedTool, and most of the same command line options are supported. The new SeedTool is more flexible and extensible, and is designed to support additional functionality.
