+# Bitwarden (unofficial) CLI plugin
+
+This plugin adds completion for [rbw](https://github.com/doy/rbw), an unofficial
+CLI for [Bitwarden](https://bitwarden.com).
+
+To use it, add `rbw` to the plugins array in your zshrc file:
+
+```zsh
+plugins=(... rbw)
+```
+
+## `rbwpw`
+
+The `rbwpw` function is a wrapper around `rbw`. It copies the password in the
+clipboard for the service you ask for and clears the clipboard 20s later.
+The usage is as follows:
+
+```zsh
+rbwpw <service>
+```
+
+This plugin does not add any aliases.
