+      gopass is a simple but powerful password manager for your terminal. It is a
+      Pass implementation in Go that can be used as a drop in replacement.
+
+      Every secret lives inside of a gpg (or: age) encrypted textfile. These secrets
+      can be organized into meaninful hierachies and are by default versioned using
+      git.
+
+      This package contains git credential helper. It can be used to store git remote
+      credentials in a password store.
