+# Resolving Docker `nginx-entrypoint.sh` Script Not Found Error on Windows
+
+If you're encountering the error `exec /usr/local/bin/nginx-entrypoint.sh: no such file or directory` in a Docker container on Windows, follow these steps to resolve the issue.
+
+## 1. Check Line Endings
+On Windows, files often have `CRLF` line endings, while Linux systems expect `LF`. This can cause issues when executing shell scripts in Linux containers.
+
+- **Convert Line Endings using `dos2unix`:**
+  ```bash
+  dos2unix resources/nginx-entrypoint.sh
