+.SH DESCRIPTION
+.BR simple_backup
+is a python script for performing backup of files and folders. It uses rsync to copy the files to the specified location.
+Parameters for the backup such as input files/directories, output location and files or folders to exclude can be specified
+in a configuration file (default location $HOME/.config/simple_backup/simple_backup.conf) or directly on the command line.
+Parameters specified on the command line will override those in the configuration file.
+.SH OPTIONS
+.TP
+.B \-h, \-\-help
+Print a short help message and exit
+.TP
+.B \-c, \-\-config FILE
+Specify the configuration file, useful to specify a different one from the default.
+.TP
+.B \-i, \-\-input INPUT [INPUT...]
+Specify the files and directories to backup. Multiple inputs can be specified, just separate them with a space.
+If filenames or paths contain spaces, don't forget to escape them, or to use single or double quotes around them.
+.TP
+.B \-o, \-\-output DIR
+Specify the directory where the files will be copied. The program will automatically create a subdirectory called
+\(aqsimple_backup\(aq (if it does not already exist) and inside this directory the actual backup directory (using
+the current date and time)
+.TP
+.B \-e, \-\-exclude FILE|DIR|PATTERN [FILE|...]]
+Specify files, directories or patterns to exclude from the backup. Matching files and directories will not be copied.
+Multiple elements can be specified, in the same way as for the \-\-input option
+.TP
+.B \-k, \-\-keep N
+Specify how many old backups (so excluding the current one) will be kept. The default behavior is to keep them all
+(same as N=\-1)
+.TP
+.B \-s, \-\-checksums
+Same as rsync option \(aq\-\-checksum\(aq, use checksums instead of mod\-time and size to skip files.
+.TP
+.B \-\-remove\-before\-backup
+Remove old backups (if necessary) before creating the new backup. Useful to free some space before performing the backup.
+Default behavior is to remove old backups after successfully completing the backup.
+.SH CONFIGURATION
+An example configuration file is provided at \(aq/etc/simple_backup/simple_backup.conf\(aq. Copy it to the default location
+($HOME/.config/simple_backup) and edit it as needed.
