-# currently only supports OpenBSD

-Documentation:
-* With pass, each password lives inside of a gpg encrypted file whose filename is
-  the title of the website or resource that requires the password.
-* These encrypted files may be organized into meaningful folder hierarchies,
-  copied from computer to computer, and in general, manipulated using standard
-  command line file management utilities.
-* All passwords live in ~/.password-store and pass provides some nice commands
-  for adding, editing, generating, and retrieving passwords.
-* You can edit the password store using ordinary unix shell commands alongside
-  the pass command.
-
-To be implemented:
-* initialize password store
-* show password
-* copy password to clipboard; -c
-* add existing password to the store using insert
-* generate password
-* remove password
-
-Potential Libraries:
-* GPGME
-
-Personal Development:
-* Knowledge in cryptography
-* Knowledge in algorithms
-* a utility I can use and share
-
-flags:
-init:	initialize new password store and use gpg-id for encryption
-ls:	list names of passwords inside the tree at subfolder by using tree(1)
-grep:	searches inside decrypted password file for search-string and displays
-	line containing matched string along with filename. (uses grep(1))
-find:	List names of passwords inside the tree that match pass-name by using
-	the tree program.
-show:	decrypt and print a password. If -c is specified, xclip is used and then
-	restore the clipboard after 45 sec.
-insert: insert a new password into the password store.  
-rm: 	remove the password from the password store.  
-mv: 	renames the password or directory named old-path to new-path

+# pass
+
+A stripped down version of the standard unix password manager "pass" in C.
+
+# Dependencies
+
+gpg2
+libgpgme
+
+# Installation
+
+Edit config.mk to match your setup (pass is installed into 
+/usr/local/ namespace by default).
+
+Post-configuration:
+
+$ make
+$ doas make install
+
+# Documentation:
+
+* With pass, each password lives inside of a gpg encrypted file whose filename is
+  the title of the website or resource that requires the password.
+* These encrypted files may be dealt with like any other file & manipulated 
+  using standard command line file management utilities.
+* Passwords live inside the respective files in ~/.password-store.
+* pass provides some commands for adding, removing and retrieving passwords.
+* Editing passwords is possible by overwriting them.
+
+# Commands
+
+init:	
+	initialize new password storage and use a gpg-uid for encryption.
+	
+insert: 
+	insert a new password into the password store.  
+
+rm: 	
+	remove password from the password store.
+
+show:
+	"show" is just a place-holder. Invoking pass with the filename will
+	decrypt it and print the password to stdout.
+
+help:
+	Show usage message.
+
+ver:
+	Show version information

+
+# Extras
+
+pkg_install tree pwgen
+
+You may use tree to view the structure of files and directories in
+~/.password-store.
+You can pipeline the output of pwgen to pass; creating complex passwords.
+	pwgen -1 | pass insert Email/userid@domain.com
+Note: pass will read input until newline.
