 spm is a single fully POSIX shell compliant script utilizing gpg2(1) in
 combination with basic tools such as find(1) and tree(1).
 
-spm stores everything in a directory structure where passwords correspond to
-individually [PGP](https://gnupg.org/) encrypted files, optionally residing inside nested
-subdirectories of arbitrary depth, where any subdirectory can be interpreted
-as a (sub)group to manage large collections easily.
+Passwords are stored as [PGP](https://gnupg.org) encrypted files with
+directories funtioning as (sub)groups.
 
-This project started as a fork of mneum's [tpm](https://github.com/nmeum/tpm) which at that time was lacking
-crucial features such as removing or listing existent entries (it still does).
+spm reads/writes passwords via standard input/output allowing you to build
+flexible and powerful management tools.
 
-spm works perfectly with standard input and output allowing easy integration
-with other tools to create a truely flexible and powerful password management
-tool.
+Refer to the manual page for various examples or read its source code to see
+how it works.
