+[![Go Report Card](https://goreportcard.com/badge/github.com/go-logr/zerologr)](https://goreportcard.com/report/github.com/go-logr/zerologr)
+
+A [logr](https://github.com/go-logr/logr) LogSink implementation using [Zerolog](https://github.com/rs/zerolog).
+
+## Usage
+
+```go
+import (
+    "os"
+
+    "github.com/go-logr/logr"
+    "github.com/go-logr/zerologr"
+    "github.com/rs/zerolog"
+)
+
+func main() {
+    zerolog.TimeFieldFormat = zerolog.TimeFormatUnixMs
+    zerologr.NameFieldName = "logger"
+    zerologr.NameSeparator = "/"
+
+    zl := zerolog.New(os.Stderr)
+    zl = zl.With().Caller().Timestamp().Logger()
+    var log logr.Logger = zerologr.New(&zl)
+
+    log.Info("Logr in action!", "the answer", 42)
+}
+```
+
+## Implementation Details
+
+For the most part, concepts in Zerolog correspond directly with those in logr.
+
+Levels in logr correspond to custom debug levels in Zerolog. Any given level
+in logr is represents by `zerologLevel = 1 - logrLevel`.
+
+For example `V(2)` is equivalent to Zerolog's `TraceLevel`, while `V(1)` is
+equivalent to Zerolog's `DebugLevel`.
