+# Library Instrumentation for JMX Metrics
+
+Provides OpenTelemetry instrumentation for [Java Management Extensions (JMX)](https://docs.oracle.com/javase/tutorial/jmx/).
+
+This instrumentation collects JMX metrics and exports them as OpenTelemetry metrics.
+
+## Quickstart
+
+### Add these dependencies to your project
+
+Replace `OPENTELEMETRY_VERSION` with the [latest release](https://central.sonatype.com/artifact/io.opentelemetry.instrumentation/opentelemetry-jmx-metrics).
+
+For Maven, add to your `pom.xml` dependencies:
+
+```xml
+<dependencies>
+  <dependency>
+    <groupId>io.opentelemetry.instrumentation</groupId>
+    <artifactId>opentelemetry-jmx-metrics</artifactId>
+    <version>OPENTELEMETRY_VERSION</version>
+  </dependency>
+</dependencies>
+```
+
+For Gradle, add to your dependencies:
+
+```kotlin
+implementation("io.opentelemetry.instrumentation:opentelemetry-jmx-metrics:OPENTELEMETRY_VERSION")
+```
+
+### Usage
+
+```java
+import io.opentelemetry.api.OpenTelemetry;
+import io.opentelemetry.instrumentation.jmx.engine.JmxMetricInsight;
+import io.opentelemetry.instrumentation.jmx.engine.MetricConfiguration;
+
+// Get an OpenTelemetry instance
+OpenTelemetry openTelemetry = ...;
+
+JmxMetricInsight jmxMetricInsight = JmxMetricInsight.createService(openTelemetry, 5000);
+
+// Configure your JMX metrics
+MetricConfiguration config = new MetricConfiguration();
+
+jmxMetricInsight.startLocal(config);
