+# OpenTelemetry OTLP exporter
+
+## Documentation
+
+https://opentelemetry.io/docs/instrumentation/php/exporters/#otlp
+
+## Usage
+
+See https://github.com/open-telemetry/opentelemetry-php/blob/main/examples/traces/exporters/otlp_http.php
+
+## Http transport
+
+```php
+$transport = (new \OpenTelemetry\Contrib\Otlp\OtlpHttpTransportFactory())->create('http://collector:4318');
+$exporter = new \OpenTelemetry\Contrib\Otlp\SpanExporter($transport);
+```
+
+## gRPC transport
+
+To export over gRPC, you will need to additionally install the `open-telemetry/transport-grpc` package.
+
+## Protobuf Runtime library
+
+OTLP exporting requires a [protobuf implementation](https://github.com/protocolbuffers/protobuf/tree/main/php).
+
+The `open-telemetry/gen-otlp-protobuf` requires the `google/protobuf` native implementation. It's fine for development, but
+not recommended for production usage.
+
+The recommended option for production is to install the Protobuf C extension for PHP. The extension
+makes exporting _significantly_ more performant. This can be easily installed with the following command:
+
+```shell
+pecl install protobuf
+```
