 # A NixOps Wrapper for Git Projects
 # ---------------------------------

-# Repo: https://github.com/grafted-in/nixops-manager
+# Modified from repo: https://github.com/grafted-in/nixops-manager
 #
 # This tool is a simple wrapper around NixOps. The goal is to make it easier to use NixOps when you
 # want to share your deployment state between members of a team.
 #
 # To achieve this, this wrapper gives every deployment as a separate state file which is placed
-# in the same directory as this script. The files have the `.nixops` extension.
+# in a sub-directory of this script. The files have the `.nixops` extension.
 #
 # You are expected to keep these files in version control. It's also *highly* recommended that you
 # use a tool like git-crypt to keep them encrypted with this entry in .gitattributes:
 #
 #    *.nixops   binary filter=git-crypt diff=git-crypt
 #
-# This tool also enforces a per-repository version of Nixpkgs via a `nixpkgs-version.sh` file in the
-# same directory as the script. This ensures that all users have a consistent version of NixOps and
-# deploy a consistent set of packages to servers.
-#
 # Most commands work identically to NixOps. However, instead of specifying deployments with
 # the `--deployment/-d` flag, you select a deployment in the first argument. In other words, instead
