+=head1 NAME
+
+Math::BigInt::GMP - backend library for Math::BigInt etc. based on GMP
+
+=head1 SYNOPSIS
+
+    # to use it with Math::BigInt
+    use Math::BigInt lib => 'GMP';
+
+    # to use it with Math::BigFloat
+    use Math::BigFloat lib => 'GMP';
+
+    # to use it with Math::BigRat
+    use Math::BigRat lib => 'GMP';
+
+=head1 DESCRIPTION
+
+Math::BigInt::GMP is a backend library for Math::BigInt, Math::BigFloat,
+Math::BigRat and related modules.
+
+Math::BigInt::GMP provides support for big integer calculations by means of the
+GMP C library. See L<https://gmplib.org/> for more information about the GMP
+library.
+
+Math::BigInt::GMP no longer uses Math::GMP, but provides its own XS layer to
+access the GMP C library. This cuts out another (Perl subroutine) layer and
+also reduces the memory footprint.
+
+Math::BigInt::GMP inherits from Math::BigInt::Lib.
+
+=head1 BUGS
+
+Please report any bugs or feature requests to
+C<bug-math-bigint-gmp at rt.cpan.org>, or through the web interface at
+L<https://rt.cpan.org/Ticket/Create.html?Queue=Math-BigInt-GMP>
+(requires login).
+We will be notified, and then you'll automatically be notified of progress on
+your bug as I make changes.
