+## why Git is not tracking this case-only rename?
+
+        Windows/macOS filesystems are case-insensitive they treat both names as the same file.So when you rename only by case, the OS reports no change.
+
+## Provide the correct steps to make Git recognize and commit the rename:
+    force Rename command : git mv -f readme.md Readme.md
+
+## Explain the underlying reason why this happens (hint: think about how Git interacts with different operating systems and filesystems).
+     
+     1. Git was designed for Linux, where filesystems are case-sensitive.
+     2. Windows/macOS filesystems are case-insensitive they treat both names as the same file.So when you rename only by case, the OS reports no change.
