-# OpenTelemetry-Go OTLP Span Exporter
-
-[![Go Reference](https://pkg.go.dev/badge/go.opentelemetry.io/otel/exporters/otlp/otlptrace.svg)](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace)
-
-[OpenTelemetry Protocol Exporter](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.20.0/specification/protocol/exporter.md) implementation.
-
-## Installation
-
-```
-go get -u go.opentelemetry.io/otel/exporters/otlp/otlptrace
-```
-
-## Examples
-
-- [HTTP Exporter setup and examples](./otlptracehttp/example_test.go)
-- [Full example of gRPC Exporter sending telemetry to a local collector](../../../example/otel-collector)
-
-## [`otlptrace`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace)
-
-The `otlptrace` package provides an exporter implementing the OTel span exporter interface.
-This exporter is configured using a client satisfying the `otlptrace.Client` interface.
-This client handles the transformation of data into wire format and the transmission of that data to the collector.
-
-## [`otlptracegrpc`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc)
-
-The `otlptracegrpc` package implements a client for the span exporter that sends trace telemetry data to the collector using gRPC with protobuf-encoded payloads.
-
-## [`otlptracehttp`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp)
-
-The `otlptracehttp` package implements a client for the span exporter that sends trace telemetry data to the collector using HTTP with protobuf-encoded payloads.
-
-## Configuration
-
-### Environment Variables
-
-The following environment variables can be used (instead of options objects) to
-override the default configuration. For more information about how each of
-these environment variables is interpreted, see [the OpenTelemetry
-specification](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.20.0/specification/protocol/exporter.md).
-

-| ------------------------------------------------------------------------ |------------------------------ | -------------------------------------------------------- |
-| `OTEL_EXPORTER_OTLP_ENDPOINT` `OTEL_EXPORTER_OTLP_TRACES_ENDPOINT`       | `WithEndpoint` `WithInsecure` | `https://localhost:4317` or `https://localhost:4318`[^1] |
-| `OTEL_EXPORTER_OTLP_CERTIFICATE` `OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE` | `WithTLSClientConfig`         |                                                          |
-| `OTEL_EXPORTER_OTLP_HEADERS` `OTEL_EXPORTER_OTLP_TRACES_HEADERS`         | `WithHeaders`                 |                                                          |
-| `OTEL_EXPORTER_OTLP_COMPRESSION` `OTEL_EXPORTER_OTLP_TRACES_COMPRESSION` | `WithCompression`             |                                                          |
-| `OTEL_EXPORTER_OTLP_TIMEOUT` `OTEL_EXPORTER_OTLP_TRACES_TIMEOUT`         | `WithTimeout`                 | `10s`                                                    |
-
-[^1]: The gRPC client defaults to `https://localhost:4317` and the HTTP client `https://localhost:4318`.
-
-Configuration using options have precedence over the environment variables.
