 `logf` is a high-performance, zero-alloc logging library for Go applications with a minimal API overhead. It's also the fastest logfmt logging library for Go.
 
-`logf` emits structured logs in [`logfmt`](https://brandur.org/logfmt) style. `logfmt` is a flexible format which involves `key=value` pairs to emit structured log lines. `logfmt` achieves the goal of generating logs that are not just machine-friendly but also readable by humans, unlike the clunky JSON lines.
