+# SSH Backup and Download Script
+#
+# Description:
+# This script connects to a remote server to perform a backup, then downloads
+# the backup files to the local machine. It uses SSH keys for secure,
+# password-less authentication.
+# 1. Connects via SSH to the remote server.
+# 2. Zips a specified directory on the remote server.
+# 3. Exports a WordPress database on the remote server.
+# 4. Downloads the zipped directory to the local ~/Downloads folder.
+# 5. Downloads the SQL database backup to the local ~/Downloads folder.
+# 6. Removes the created backup files from the remote server.
+#
+# Usage:
+# ./connect.sh
+#
+# ==============================================================================
