-    Decorator to start a child span under the existing current transaction.
-    If there is no current transaction, then nothing will be traced.
+    Decorator to start a child span around a function call.
 
-    .. code-block::
-        :caption: Usage
+    This decorator automatically creates a new span when the decorated function
+    is called, and finishes the span when the function returns or raises an exception.
+
+    :param func: The function to trace. When used as a decorator without parentheses,
+        this is the function being decorated. When used with parameters (e.g.,
+        ``@trace(op="custom")``, this should be None.
+    :type func: Callable or None
+
+    :param op: The operation name for the span. This is a high-level description
+        of what the span represents (e.g., "http.client", "db.query").
+        You can use predefined constants from :py:class:`sentry_sdk.consts.OP`
+        or provide your own string. If not provided, a default operation will
+        be assigned based on the template.
+    :type op: str or None
+
+    :param name: The human-readable name/description for the span. If not provided,
+        defaults to the function name. This provides more specific details about
+        what the span represents (e.g., "GET /api/users", "process_user_data").
+    :type name: str or None
+
+    :param attributes: A dictionary of key-value pairs to add as attributes to the span.
+        Attribute values must be strings, integers, floats, or booleans. These
+        attributes provide additional context about the span's execution.
+    :type attributes: dict[str, Any] or None
+
+    :returns: When used as ``@trace``, returns the decorated function. When used as
+        ``@trace(...)`` with parameters, returns a decorator function.
+    :rtype: Callable or decorator function
+
+    Example::
 
         import sentry_sdk
+        from sentry_sdk.consts import OP
 
+        # Simple usage with default values
