 OpenTelemetry Util for GenAI
 ============================
 
+The GenAI Utils package provides boilerplate and helpers to standardize instrumentation for Generative AI.
+It offers APIs to minimize the work needed to instrument GenAI libraries,
+while providing standardization for generating spans, metrics, and events.
 
-The GenAI Utils package will include boilerplate and helpers to standardize instrumentation for Generative AI. 
-This package will provide APIs and decorators to minimize the work needed to instrument genai libraries, 
-while providing standardization for generating both types of otel, "spans and metrics" and "spans, metrics and events"
 
-This package relies on environment variables to configure capturing of message content. 
+Key Components
+--------------
+
+- ``TelemetryHandler`` -- manages LLM invocation lifecycles (spans, metrics, events)
+- ``LLMInvocation`` and message types (``Text``, ``Reasoning``, ``Blob``, etc.) -- structured data model for GenAI interactions
+- ``CompletionHook`` -- protocol for uploading content to external storage (built-in ``fsspec`` support)
+- Metrics -- ``gen_ai.client.operation.duration`` and ``gen_ai.client.token.usage`` histograms
+
+
+Usage
+-----
+
+See the module docstring in ``opentelemetry.util.genai.handler`` for usage examples,
+including context manager and manual lifecycle patterns.
+
+
+Environment Variables
+---------------------
+
+This package relies on environment variables to configure capturing of message content.
 By default, message content will not be captured.
-Set the environment variable `OTEL_SEMCONV_STABILITY_OPT_IN` to `gen_ai_latest_experimental` to enable experimental features.
-Set the environment variable `OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT` to one of:
-- `NO_CONTENT`: Do not capture message content (default).
-- `SPAN_ONLY`: Capture message content in spans only.
-- `EVENT_ONLY`: Capture message content in events only.
-- `SPAN_AND_EVENT`: Capture message content in both spans and events.
-
-To control event emission, you can optionally set `OTEL_INSTRUMENTATION_GENAI_EMIT_EVENT` to `true` or `false` (case-insensitive).
-This variable controls whether to emit `gen_ai.client.inference.operation.details` events.
-If not explicitly set, the default value is automatically determined by `OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT`:
-- When `NO_CONTENT` or `SPAN_ONLY` is set: defaults to `false`
-- When `EVENT_ONLY` or `SPAN_AND_EVENT` is set: defaults to `true`
+Set the environment variable ``OTEL_SEMCONV_STABILITY_OPT_IN`` to ``gen_ai_latest_experimental`` to enable experimental features.
+Set the environment variable ``OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT`` to one of:
+
+- ``NO_CONTENT``: Do not capture message content (default).
+- ``SPAN_ONLY``: Capture message content in spans only.
+- ``EVENT_ONLY``: Capture message content in events only.
+- ``SPAN_AND_EVENT``: Capture message content in both spans and events.
+
+To control event emission, you can optionally set ``OTEL_INSTRUMENTATION_GENAI_EMIT_EVENT`` to ``true`` or ``false`` (case-insensitive).
+This variable controls whether to emit ``gen_ai.client.inference.operation.details`` events.
+If not explicitly set, the default value is automatically determined by ``OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT``:
+
+- When ``NO_CONTENT`` or ``SPAN_ONLY`` is set: defaults to ``false``
+- When ``EVENT_ONLY`` or ``SPAN_AND_EVENT`` is set: defaults to ``true``
+
 If explicitly set, the user's value takes precedence over the default.
 
-This package provides these span attributes:
-
-- `gen_ai.provider.name`: Str(openai)
-- `gen_ai.operation.name`: Str(chat)
-- `gen_ai.request.model`: Str(gpt-3.5-turbo)
-- `gen_ai.response.finish_reasons`: Slice(["stop"])
-- `gen_ai.response.model`: Str(gpt-3.5-turbo-0125)
-- `gen_ai.response.id`: Str(chatcmpl-Bz8yrvPnydD9pObv625n2CGBPHS13)
-- `gen_ai.usage.input_tokens`: Int(24)
-- `gen_ai.usage.output_tokens`: Int(7)
-- `gen_ai.input.messages`: Str('[{"role": "Human", "parts": [{"content": "hello world", "type": "text"}]}]')
-- `gen_ai.output.messages`: Str('[{"role": "AI", "parts": [{"content": "hello back", "type": "text"}], "finish_reason": "stop"}]')
-- `gen_ai.system_instructions`: Str('[{"content": "You are a helpful assistant.", "type": "text"}]') (when system instruction is provided)
-
-This package also supports embedding invocation spans via the `embedding` context manager.
-For embedding invocations, common attributes include:
-
-- `gen_ai.provider.name`: Str(openai)
-- `gen_ai.operation.name`: Str(embeddings)
-- `gen_ai.request.model`: Str(text-embedding-3-small)
-- `gen_ai.embeddings.dimension.count`: Int(1536)
-- `gen_ai.request.encoding_formats`: Slice(["float"])
-- `gen_ai.usage.input_tokens`: Int(24)
-- `server.address`: Str(api.openai.com)
-- `server.port`: Int(443)
-
-When `EVENT_ONLY` or `SPAN_AND_EVENT` mode is enabled and a LoggerProvider is configured, 
-the package also emits `gen_ai.client.inference.operation.details` events with structured 
-message content (as dictionaries instead of JSON strings). Note that when using `EVENT_ONLY` 
-or `SPAN_AND_EVENT`, the `OTEL_INSTRUMENTATION_GENAI_EMIT_EVENT` environment variable defaults 
-to `true`, so events will be emitted automatically unless explicitly set to `false`.
