 .SH "DESCRIPTION"
-This program is a free (GPL) utility designed to create self-extractable
-archives from a directory.
+This program is a free (GPL) shell utility designed to create self-extractable
+compressed archives from a directory. The resulting file appears as a shell script, and can be launched as is. The archive
+will then uncompress itself to a temporary directory and an optional arbitrary
+command will be executed (for example an installation script). 
+.TP
+Makeself archives also include checksums for integrity self-validation (CRC and/or MD5/SHA256 checksums).
