+
+qt-integer-sign-comparison
+=============================
+
+The qt-integer-sign-comparison check is an alias, please see
+:doc:`modernize-use-integer-sign-comparison <../modernize/use-integer-sign-comparison>`
+for more information.
+
+Examples of fixes created by the check:
+
+.. code-block:: c++
+
+    uint func(int bla)
+    {
+        uint result;
+        if (result == bla)
+            return 0;
+
+        return 1;
+    }
+
+in C++17 becomes
+
+.. code-block:: c++
+
+    <QtCore/q20utility.h>
+
+    uint func(int bla)
+    {
+        uint result;
+        if (q20::cmp_equal(result, bla))
+            return 0;
+
+        return 1;
+    }
+
+in C++20 becomes
+
+.. code-block:: c++
+
+    #include <utility>
+
+    uint func(int bla)
+    {
+        uint result;
+        if (std::cmp_equal(result, bla))
+            return 0;
+
+        return 1;
+    }
+
+Options
+-------
+
+.. option:: IncludeStyle
+
+  A string specifying which include-style is used, `llvm` or `google`.
+  Default is `llvm`.
+
+.. option:: IsQtApplication
+
+  When `true`, then it is assumed that the code being analyzed is the Qt-based code.

Sounds better
