+modernize-make-unique
+=====================
+
+This check finds the creation of ``std::unique_ptr`` objects by explicitly
+calling the constructor and a ``new`` expression, and replaces it with a call
+to ``std::make_unique``, introduced in C++14.
+
+.. code-block:: c++
+
+  auto my_ptr = std::unique_ptr<MyPair>(new MyPair(1, 2));
+
+  // becomes
+
+  auto my_ptr = std::make_unique<MyPair>(1, 2);

+New expressions
+---------------
+
+Frequently, when a pointer is declared and initialized with ``new``, the
+pointee type has to be written twice: in the declaration type and in the
+``new`` expression. In this cases, the declaration type can be replaced with
