readme.md

+- Created readme.md in a repo and renamed it to README.md
+- ![Repository_Screenshot](readme.png)
+- Git didn’t show changes because windows system is case-insensitive
+- Fixed it using:
+    `git mv -f readme.md README.md`
+    `git commit -m "Rename readme.md to README.md"`
+- Reason: Git is case-sensitive, but case-insensitive filesystems treat both names as the same
