 `tessen` is written to work only on wayland compositors such as [sway](https://swaywm.org/). If
 you'd rather use [fzf](https://github.com/junegunn/fzf) to copy your password-store data on both
 xorg/x11 and wayland, check out [pass-tessen](https://github.com/ayushnix/pass-tessen).
 
 ### Why use `tessen`?
 
-- `tessen` can autotype or copy (or do both at the same time!) your password store data including
-  all of your key-value pair data

-  From what I've observed as of this commit, most scripts out there do not autotype and copy all of
-  your key-value pair data. They also do not offer choices about autotyping or copying data with the
-  same flexibility as `tessen` does.

   Although [rofi-pass](https://github.com/carnager/rofi-pass) is a good alternative, it only works
   on xorg/x11. `tessen` is made to work on wayland.
 
-- `tessen` does not use any external programs unless they are needed. This means that `tessen`
-  doesn't need programs like `sed`, `awk`, `tr`, `cut`, `find`, `sort`, `head`, `tail`. This ensures
-  that `tessen` isn't dependent on the subtle differences between GNU, BSD, and busybox coreutils.

 - the code is linted using [shellcheck](https://github.com/koalaman/shellcheck) and formatted using
   [shfmt](https://github.com/mvdan/sh). I've also tried to ensure that `tessen` doesn't leak any
   sensitive data. Please raise an issue or a pull request if you can make tessen more minimalistic
   or secure.

+### Optional Steps and Minimal Installation
+
+There's an optional patch provided in the repository called `explicit_path.patch` which can be used
+to change the shebang from `#!/usr/bin/env bash` to `#!/bin/bash`. It also exports `$PATH` to
+
+```
+/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
+```
+
+to prevent execution of arbitrary binaries not owned by the root user. If you want to apply this
+patch, execute
+
+```
+patch -i explicit_path.patch tessen
+```
+
+before executing `sudo make install`. This patch should make `tessen` work fine on almost all Linux
+distributions except perhaps NixOS and GuixSD.
+
+If you don't want to build the man pages or install the shell completion files, you can use
+
+```
+sudo make minimal
+```
+
+to install the tessen script and nothing else. The man pages can be installed if needed using `sudo
+make man`, the bash completion file can be installed using `sudo make bashcomp`, and the fish
+completion file can be installed using `sudo make fishcomp`.
