 **Roughenough** is a [Roughtime](https://roughtime.googlesource.com/roughtime) secure time 
 synchronization server implemented in Rust.
 
-The server is functionally complete: it parses client requests and generates valid Roughtime responses.
-However rough edges and unimplemented features remain, see [Limitations](#limitations) below. 
+The server is bare-bones, but functionally complete: it parses client requests and generates valid Roughtime responses.
