+readability-use-std-min-max
+========================
+
+Replaces certain conditional statements with equivalent ``std::min`` or ``std::max`` expressions, 
+improving readability and promoting the use of standard library functions.
+Note: While this transformation improves code clarity, it may not be
+suitable for performance-critical code. Using ``std::min`` or ``std::max`` can
+introduce additional stores, potentially impacting performance compared to
+the original if statement that only assigns when the value needs to change.
+
+Examples:
+
+Before:
+
+.. code-block:: c++
+
+  void foo(){
+    int a,b;
+    if(a < b)
+        a = b;
+    }
+
+
+After:
+

+    a = std::max(a, b);

 readability-use-std-min-max
 ===========================
 
-Replaces certain conditional statements with equivalent ``std::min`` or ``std::max`` expressions, 
-improving readability and promoting the use of standard library functions.
-Note: this transformation may impact performance in performance-critical code due to potential 
-additional stores compared to the original if statement.
+Replaces certain conditionals with ``std::min`` or ``std::max`` for readability,
+promoting use of standard library functions. Note: This may impact
+performance in critical code due to potential additional stores compared
