-age is meant to be a simple, secure and modern encryption tool with small explicit keys, no config options, and UNIX-style composability. The spec is at [age-tool.com](https://age-tool.com).
+age is meant to be a simple, secure and modern encryption tool with small explicit keys, no config options, and UNIX-style composability. The spec is at [age-tool.com/spec](https://age-tool.com/spec).
