+#!/bin/bash
+
+# This script creates a .tar.xz archive of a specified source directory, preserving file permissions,
+# and names the archive using the source directory's name followed by the current date in DDMMYYYY format.
+# Additionally, it generates a SHA-256 checksum file for the archive in the specified output directory.
+
+# Usage:
+# 1. Make the script executable: `chmod +x archive_with_checksum`
+# 2. Run the script by providing the path to the source directory as the first argument
+#    and the path to the output directory as the second argument.
+#    Example: `./archive_with_checksum /path/to/source_directory /path/to/output_directory`
+#
+# The script will produce an archive named `source_directory_DDMMYYYY.tar.xz` and a checksum file
+# named `source_directory_DDMMYYYY.tar.xz.sha256` in the specified output directory.
+
+# Check if the correct number of arguments is provided
+if [ "$#" -ne 2 ]; then
