+# Pass Custom Completions
+
+This script provides custom completions for most pass commands. It can be
+imported with the following command:
+
+```nu
+source path/to/pass/pass-completions.nu
+```
+
+Where `path/to` is the relative of absolute pass to the pass completions file.
+
+More information about the pass password manager can be found at
+https://www.passwordstore.org/.
