+/**
+ * This module provides an easy way to integrate <a href="https://openjdk.org/projects/code-tools/jmh/">JMH</a> benchmarking with Mill.
+ *
+ * Example configuration:
+ * {{{
+ * import mill._, scalalib._
+ *
+ * import $ivy.`com.lihaoyi::mill-contrib-jmh:$MILL_VERSION`
+ * import contrib.jmh.JmhModule
+ *
+ * object foo extends ScalaModule with JmhModule {
+ *   def scalaVersion = "2.13.8"
+ *   def jmhCoreVersion = "1.35"
+ * }
+ * }}}
+ *
+ * Here are some sample commands:
+ * - mill foo.runJmh             # Runs all detected jmh benchmarks
+ * - mill foo.listJmhBenchmarks  # List detected jmh benchmarks
+ * - mill foo.runJmh -h          # List available arguments to runJmh
+ * - mill foo.runJmh regexp      # Run all benchmarks matching `regexp`
+ *
+ * For Scala JMH samples see:
+ * [[https://github.com/sbt/sbt-jmh/tree/main/plugin/src/sbt-test/sbt-jmh/run/src/main/scala/org/openjdk/jmh/samples]].

+= JMH
+
+You can use `JmhModule` to integrate JMH testing with Mill.
+
+Example configuration:
+
+.`build.sc`
+[source,scala]
+----
+import mill._, scalalib._
+
+import $ivy.`com.lihaoyi::mill-contrib-jmh:$MILL_VERSION`
+import contrib.jmh.JmhModule
+
+object foo extends ScalaModule with JmhModule {
+  def scalaVersion = "2.13.8"
+  def jmhCoreVersion = "1.35"
+}
+----
+
+Here are some sample commands:
+
+[source,bash]
+----
+mill foo.runJmh             # Runs all detected jmh benchmarks
+mill foo.listJmhBenchmarks  # List detected jmh benchmarks
+mill foo.runJmh -h          # List available arguments to runJmh
+mill foo.runJmh regexp      # Run all benchmarks matching `regexp`
+----
+
+For Scala JMH samples see https://github.com/sbt/sbt-jmh/tree/main/plugin/src/sbt-test/sbt-jmh/run/src/main/scala/org/openjdk/jmh/samples[sbt-jmh].
