+## Running without an Agent
+If you want to use Sentry with OpenTelemetry without an agent, you can do so by adding the `sentry-opentelemetry-agentless` (or `sentry-opentelemetry-agentless-spring`) module as dependency to your project. 
+
+And run your application with the following JVM arguments:
+```
+-Dotel.java.global-autoconfigure.enabled=true
+```
+You may also want to set the following environment variables to if you do not use OpenTelemetry exporters:
+`OTEL_LOGS_EXPORTER=none;OTEL_METRICS_EXPORTER=none;OTEL_TRACES_EXPORTER=none`
+
+Alternatively you can initialize OpenTelemetry programmatically like this:
+
+```java
+// Initialize OpenTelemetry by using the AutoConfiguredOpenTelemetrySdk which automatically
+// registers the `SentrySpanProcessor` and `SentryPropagator` and others.
+// Also, you need to disable the OTEL exporters if you do not use them.

+    properties.put("otel.traces.exporter", "none");
+    return properties;
+  })
+  .build();
+```
+
+And then initialize Sentry as usual:
+
+```java
+// Initialize Sentry
+Sentry.init(
+    options -> {
+    options.setDsn("...");
+      ...

-*NOTE: Our OpenTelemetry modules are still experimental. Any feedback is welcome.*
+This module allows the use of Sentry with OpenTelemetry in SpringBoot without an agent by using the OpenTelemetry Spring Boot Starter.
+For guidance on when to use this module instead of the agent, please have a look at the [OpenTelemetry Spring Boot Starter documentation](https://opentelemetry.io/docs/zero-code/java/spring-boot-starter/).
