 # Crate of the Week
 
-This week, we don't have one, nor two, but *three* crates of the week! There's [Watt](https://github.com/dtolnay/watt), a fast WASM-based proc-macro runtime, [Anyhow](https://github.com/dtolnay/anyhow), yet another error handling crate and [spotify-tui](https://github.com/Rigellute/spotify-tui), a console user interface for Spotify.
+This week's crate is [grubbnet](https://github.com/dooskington/grubbnet), a TCP client/server library for networked applications and games.
