+----------------\n\
+This GUI program is primarily for safely writing a bootable ISO image to a USB flash drive, an operation devious & potentially hazardous when done by hand. As a bonus, it can also back up the entire previous contents of the flash drive onto the hard disc, and restore the flash drive to its previous state subsequently. It gives also a feature for formatting the USB device.\n\
+\n\
+IsoDumper can be launched either from the menus, or a user or root console with the command 'isodumper'. For normal users, the root password is solicited; this is necessary for the program's operation. The flash drive can be inserted beforehand or once the program is started. In the latter case, a dialogue will say that there is no flash drive inserted, and allow a 'retry' to find it once it is. (You may have to close any automatically opened File Manager window).\n\
+\n\
+The fields of the main window are as follows:\n\
+- Device to work on: the device of the USB flash drive, a drop-down list to choose from.\n\
+- Write Image: to choose the source ISO image *.iso (or flash drive backup file *.img) to write out.\n\
+- Write to device: This button launches the operation - with a prior warning dialogue. The operation is shown in the progress bar beneath.\n\
+- Backup in: define the name and placement of the backup image file. The current flash drive will be backed up to a disc file. Note that the entire flash drive is preserved, regardless of its actual contents; ensure that you have the necessary free disc space (the same size as the USB device). This backup file can be used later to restore the flash drive by selecting it as the source *.img file to write out.\n\
+- Backup the device: launch the backup operation.\n\
+- Format the device:  create an unique partition on the entire volume in the specified format in FAT, NTFS or ext. You can specify a volume name and the format in a new dialog box.\n"))
