 ### Features
 
+- Add `sentry-opentelemetry-agentless-spring` module ([#4000](https://github.com/getsentry/sentry-java/pull/4000))
+  - This module can be added as a dependency when using Sentry with OpenTelemetry and Spring Boot but don't want to use our Agent. It takes care of configuring OpenTelemetry for use with Sentry.
+  - You may want to set `OTEL_LOGS_EXPORTER=none;OTEL_METRICS_EXPORTER=none;OTEL_TRACES_EXPORTER=none` env vars to not have the log flooded with error messages regarding OpenTelemetry features we don't use.
 - Add `sentry-opentelemetry-agentless` module ([#3961](https://github.com/getsentry/sentry-java/pull/3961))
   - This module can be added as a dependency when using Sentry with OpenTelemetry but don't want to use our Agent. It takes care of configuring OpenTelemetry for use with Sentry.
   - To enable the auto configuration of it, please set `-Dotel.java.global-autoconfigure.enabled=true` on the `java` command, when starting your application.

+# sentry-opentelemetry-agentless-spring
+
+*NOTE: Our OpenTelemetry modules are still experimental. Any feedback is welcome.*
+
+## How to use it
+
+Add the latest `sentry-opentelemetry-agentless-spring` module as a dependency and add a `sentry.properties` 
+configuration file to your project that could look like this:
+
+```properties
+# NOTE: Replace the test DSN below with YOUR OWN DSN to see the events from this app in your Sentry project/dashboard
+dsn=https://[email protected]/5428563
+traces-sample-rate=1.0
+```
+
+For more details on configuring Sentry via `sentry.properties` please see the
+[docs page](https://docs.sentry.io/platforms/java/configuration/).
+
+As an alternative to the `SENTRY_PROPERTIES_FILE` environment variable you can provide individual
+settings as environment variables (e.g. `SENTRY_DSN=...`) or you may initialize `Sentry` inside
+your target application. If you do so, please make sure to apply OpenTelemetry specific options, e.g.
+like this:
+
+```
+Sentry.init(
+        options -> {
+          options.setDsn("...");
+          ...
+          OpenTelemetryUtil.applyOpenTelemetryOptions(options, false);
+        }
+)
+```
+
+## Getting rid of exporter error messages
+
+In case you are using this module without needing to use any OpenTelemetry exporters you can add
+the following environment variables to turn off exporters and stop seeing error messages about 
+servers not being reachable in the logs.
+
+Example log message:
+```
+ERROR io.opentelemetry.exporter.internal.grpc.OkHttpGrpcExporter - Failed to export spans. The request could not be executed. Full error message: Failed to connect to localhost/[0:0:0:0:0:0:0:1]:4317
+ERROR io.opentelemetry.exporter.internal.grpc.OkHttpGrpcExporter - Failed to export metrics. The request could not be executed. Full error message: Failed to connect to localhost/[0:0:0:0:0:0:0:1]:4317
+```
+
+### Traces
+
+To turn off exporting of traces you can set `OTEL_TRACES_EXPORTER=none`
+see [OpenTelemetry GitHub](https://github.com/open-telemetry/opentelemetry-java/tree/main/sdk-extensions/autoconfigure#otlp-exporter-span-metric-and-log-exporters)
+
+### Metrics
+
+To turn off exporting of metrics you can set `OTEL_METRICS_EXPORTER=none`
+see [OpenTelemetry GitHub](https://github.com/open-telemetry/opentelemetry-java/tree/main/sdk-extensions/autoconfigure#otlp-exporter-span-metric-and-log-exporters)
