+// Package protoreflect provides interfaces to dynamically manipulate messages.
+//
+// This package includes type descriptors which describe the structure of types
+// defined in proto source files and value interfaces which provide the
+// ability to examine and manipulate the contents of messages.
+//
+//
+// Protocol Buffer Descriptors
+//
+// Protobuf descriptors (e.g., EnumDescriptor or MessageDescriptor)
+// are immutable objects that represent protobuf type information.
+// They are wrappers around the messages declared in descriptor.proto.
+// Protobuf descriptors alone lack any information regarding Go types.
+//
+// Enums and messages generated by this module implement Enum and ProtoMessage,
+// where the Descriptor and ProtoReflect.Descriptor accessors respectively
+// return the protobuf descriptor for the values.
+//
+// The protobuf descriptor interfaces are not meant to be implemented by
+// user code since they might need to be extended in the future to support
+// additions to the protobuf language.
+// The "google.golang.org/protobuf/reflect/protodesc" package converts between
+// google.protobuf.DescriptorProto messages and protobuf descriptors.
+//
+//
+// Go Type Descriptors
+//
+// A type descriptor (e.g., EnumType or MessageType) is a constructor for
+// a concrete Go type that represents the associated protobuf descriptor.
+// There is commonly a one-to-one relationship between protobuf descriptors and
+// Go type descriptors, but it can potentially be a one-to-many relationship.
+//
+// Enums and messages generated by this module implement Enum and ProtoMessage,
+// where the Type and ProtoReflect.Type accessors respectively
+// return the protobuf descriptor for the values.
+//
+// The "google.golang.org/protobuf/types/dynamicpb" package can be used to
+// create Go type descriptors from protobuf descriptors.
+//
+//
+// Value Interfaces
+//
+// The Enum and Message interfaces provide a reflective view over an
+// enum or message instance. For enums, it provides the ability to retrieve
+// the enum value number for any concrete enum type. For messages, it provides
+// the ability to access or manipulate fields of the message.
+//
+// To convert a proto.Message to a protoreflect.Message, use the
+// former's ProtoReflect method. Since the ProtoReflect method is new to the
+// v2 message interface, it may not be present on older message implementations.
+// The "github.com/golang/protobuf/proto".MessageReflect function can be used
+// to obtain a reflective view on older messages.
+//
+//
+// Relationships
+//
+// The following diagrams demonstrate the relationships between
+// various types declared in this package.
