+**NOTE** Tracing support is experimental--releases may contain tracing-related breaking changes.
+
+## `IPFS_TRACING`
+Enables OpenTelemetry tracing.
+
+Default: false
+
+## `IPFS_TRACING_JAEGER`

+
+### How to use Jaeger UI
+
+One can use the `jaegertracing/all-in-one` Docker image to run a full Jaeger
+stack and configure go-ipfs to publish traces to it (here, in an ephemeral
+container):
+
+```console
+$ docker run --rm -it --name jaeger \
+ -e COLLECTOR_ZIPKIN_HOST_PORT=:9411 \
+ -p 5775:5775/udp \
+ -p 6831:6831/udp \
+ -p 6832:6832/udp \
+ -p 5778:5778 \

+ -p 14250:14250 \
+ -p 9411:9411 \
+ jaegertracing/all-in-one
+```
+
+Then, in other terminal, start go-ipfs with Jaeger tracing enabled:
+```
+$ IPFS_TRACING=1 IPFS_TRACING_JAEGER=1 ipfs daemon
+```
+
+Finally, the [Jaeger UI](https://github.com/jaegertracing/jaeger-ui#readme) is available at http://localhost:16686
+
+
+## `IPFS_TRACING_OTLP_HTTP`
+Enables the OTLP HTTP exporter for OpenTelemetry.

+
+## `IPFS_TRACING_FILE`
+Enables the file exporter for OpenTelemetry, writing traces to the given file in JSON format.
+
+Example: "/var/log/ipfs-traces.json"
+
+Default: "" (disabled)

+// Package tracing contains the tracing logic for go-ipfs, including configuring the tracer and
+// helping keep consistent naming conventions across the stack.
+//
+// NOTE: Tracing is currently experimental. Span names may change unexpectedly, spans may be removed,
+// and backwards-incompatible changes may be made to tracing configuration, options, and defaults.
+//
+// go-ipfs uses OpenTelemetry as its tracing API, and when possible, standard OpenTelemetry environment
+// variables can be used to configure it. Multiple exporters can also be installed simultaneously,
+// including one that writes traces to a JSON file on disk.
+//
+// In general, tracing is configured through environment variables. The IPFS-specific environment variables are:
+//
+// - IPFS_TRACING: enable tracing in go-ipfs
+// - IPFS_TRACING_JAEGER: enable the Jaeger exporter
+// - IPFS_TRACING_RATIO: the ratio of traces to export, defaults to 1 (export everything)
+// - IPFS_TRACING_FILE: write traces to the given filename
+// - IPFS_TRACING_OTLP_HTTP: enable the OTLP HTTP exporter
+// - IPFS_TRACING_OTLP_GRPC: enable the OTLP gRPC exporter
+//
+// Different exporters have their own set of environment variables, depending on the exporter. These are typically
+// standard environment variables. Some common ones:
+//
+// Jaeger:
+//
+// - OTEL_EXPORTER_JAEGER_AGENT_HOST
+// - OTEL_EXPORTER_JAEGER_AGENT_PORT
+// - OTEL_EXPORTER_JAEGER_ENDPOINT
+// - OTEL_EXPORTER_JAEGER_USER
+// - OTEL_EXPORTER_JAEGER_PASSWORD
+//
+// OTLP HTTP/gRPC:
+//
+// - OTEL_EXPORTER_OTLP_ENDPOINT
+// - OTEL_EXPORTER_OTLP_CERTIFICATE
+// - OTEL_EXPORTER_OTLP_HEADERS
+// - OTEL_EXPORTER_OTLP_COMPRESSION
+// - OTEL_EXPORTER_OTLP_TIMEOUT
+//
+// For example, if you run a local IPFS daemon, you can use the jaegertracing/all-in-one Docker image to run
+// a full Jaeger stack and configure go-ipfs to publish traces to it:
+//
+// docker run -d --name jaeger \
+// -e COLLECTOR_ZIPKIN_HOST_PORT=:9411 \
+// -p 5775:5775/udp \
+// -p 6831:6831/udp \
+// -p 6832:6832/udp \
+// -p 5778:5778 \
+// -p 16686:16686 \
+// -p 14268:14268 \
+// -p 14250:14250 \
+// -p 9411:9411 \
+// jaegertracing/all-in-one
+// IPFS_TRACING=1 IPFS_TRACING_JAEGER=1 ipfs daemon
+//
+// In this example the Jaeger UI is available at http://localhost:16686.
+//
+//
+// Implementer Notes
+//
+// Span names follow a convention of ., some examples:
+//
+// - component=Gateway + span=Request -> Gateway.Request
+// - component=CoreAPI.PinAPI + span=Verify.CheckPin -> CoreAPI.PinAPI.Verify.CheckPin
+//
+// We follow the OpenTelemetry convention of using whatever TracerProvider is registered globally.
