+angou (暗号)
+============
+A simple password manager written in POSIX shell.
+
+Dependencies
+------------
+- POSIX-compliant environment
+- gnupg
+- tree (for listing all your passwords and their directories)
+  - a simple version is available in https://github.com/pyr/tree
+    and in OpenBSD's ports
+- xsel (for copying password to clipboard, but can be changed to a different
+        command with the ANGOU_CLIPBOARD command that accepts stdin)
+
+Why should I use this over password-store?
+------------------------------------------
+Don't. For a serious answer, it's because this doesn't depend on bash.
+
+Migrating from password-store
+-----------------------------
+Set the ANGOU_DIR environment variable to your password store directory.
