+Configuration
+-------------
+
+Exclude lists
+*************
+To exclude certain URLs from tracking, set the environment variable ``OTEL_PYTHON_FASTAPI_EXCLUDED_URLS``
+(or ``OTEL_PYTHON_EXCLUDED_URLS`` to cover all instrumentations) to a string of comma delimited regexes that match the
+URLs.
+
+For example,
+
+::
+
+    export OTEL_PYTHON_FASTAPI_EXCLUDED_URLS="client/.*/info,healthcheck"
+
+will exclude requests such as ``https://site/client/123/info`` and ``https://site/xyz/healthcheck``.
+
+You can also pass comma delimited regexes directly to the ``instrument_app`` method:
+
+.. code-block:: python
+
+    FastAPIInstrumentor.instrument_app(app, excluded_urls="client/.*/info,healthcheck")
+
+Request/Response hooks
+**********************
+
+This instrumentation supports request and response hooks. These are functions that get called
+right after a span is created for a request and right before the span is finished for the response.
+
+- The server request hook is passed a server span and ASGI scope object for every incoming request.
+- The client request hook is called with the internal span, and ASGI scope and event when the method ``receive`` is called.
+- The client response hook is called with the internal span, and ASGI scope and event when the method ``send`` is called.
+
+.. code-block:: python
+
+    def server_request_hook(span: Span, scope: dict[str, Any]):
+        if span and span.is_recording():
+            span.set_attribute("custom_user_attribute_from_request_hook", "some-value")
+
+    def client_request_hook(span: Span, scope: dict[str, Any], message: dict[str, Any]):
+        if span and span.is_recording():
+            span.set_attribute("custom_user_attribute_from_client_request_hook", "some-value")
+
+    def client_response_hook(span: Span, scope: dict[str, Any], message: dict[str, Any]):
+        if span and span.is_recording():
+            span.set_attribute("custom_user_attribute_from_response_hook", "some-value")
+
+   FastAPIInstrumentor().instrument(server_request_hook=server_request_hook, client_request_hook=client_request_hook, client_response_hook=client_response_hook)
+
+Capture HTTP request and response headers
+*****************************************
+You can configure the agent to capture specified HTTP headers as span attributes, according to the
+`semantic convention <https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/semantic_conventions/http.md#http-request-and-response-headers>`_.
+
+Request headers
+***************
+To capture HTTP request headers as span attributes, set the environment variable
+``OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_REQUEST`` to a comma delimited list of HTTP header names,
+or pass the ``http_capture_headers_server_request`` keyword argument to the ``instrument_app`` method.
+
+For example using the environment variable,
+::
+
+    export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_REQUEST="content-type,custom_request_header"
+
+will extract ``content-type`` and ``custom_request_header`` from the request headers and add them as span attributes.
+
+Request header names in FastAPI are case-insensitive. So, giving the header name as ``CUStom-Header`` in the environment
+variable will capture the header named ``custom-header``.
+
+Regular expressions may also be used to match multiple headers that correspond to the given pattern.  For example:
+::
+
+    export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_REQUEST="Accept.*,X-.*"
+
+Would match all request headers that start with ``Accept`` and ``X-``.
+
+To capture all request headers, set ``OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_REQUEST`` to ``".*"``.
+::
+
+    export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_REQUEST=".*"
+
+The name of the added span attribute will follow the format ``http.request.header.<header_name>`` where ``<header_name>``
+is the normalized HTTP header name (lowercase, with ``-`` replaced by ``_``). The value of the attribute will be a
+single item list containing all the header values.
+
+For example:
+``http.request.header.custom_request_header = ["<value1>", "<value2>"]``
+
+Response headers
+****************
+To capture HTTP response headers as span attributes, set the environment variable
+``OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_RESPONSE`` to a comma delimited list of HTTP header names,
+or pass the ``http_capture_headers_server_response`` keyword argument to the ``instrument_app`` method.
+
+For example using the environment variable,
+::
+
+    export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_RESPONSE="content-type,custom_response_header"
+
+will extract ``content-type`` and ``custom_response_header`` from the response headers and add them as span attributes.
+
+Response header names in FastAPI are case-insensitive. So, giving the header name as ``CUStom-Header`` in the environment
+variable will capture the header named ``custom-header``.
+
+Regular expressions may also be used to match multiple headers that correspond to the given pattern.  For example:
+::
+
+    export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_RESPONSE="Content.*,X-.*"
+
+Would match all response headers that start with ``Content`` and ``X-``.
+
+To capture all response headers, set ``OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_RESPONSE`` to ``".*"``.
+::
+
+    export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SERVER_RESPONSE=".*"
+
+The name of the added span attribute will follow the format ``http.response.header.<header_name>`` where ``<header_name>``
+is the normalized HTTP header name (lowercase, with ``-`` replaced by ``_``). The value of the attribute will be a
+list containing the header values.
+
+For example:
+``http.response.header.custom_response_header = ["<value1>", "<value2>"]``
+
+Sanitizing headers
+******************
+In order to prevent storing sensitive data such as personally identifiable information (PII), session keys, passwords,
+etc, set the environment variable ``OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SANITIZE_FIELDS``
+to a comma delimited list of HTTP header names to be sanitized, or pass the ``http_capture_headers_sanitize_fields``
+keyword argument to the ``instrument_app`` method.
+
+Regexes may be used, and all header names will be matched in a case-insensitive manner.
+
+For example using the environment variable,
+::
+
+    export OTEL_INSTRUMENTATION_HTTP_CAPTURE_HEADERS_SANITIZE_FIELDS=".*session.*,set-cookie"
+
+will replace the value of headers such as ``session-id`` and ``set-cookie`` with ``[REDACTED]`` in the span.
+
+Note:
+    The environment variable names used to capture HTTP headers are still experimental, and thus are subject to change.
