parinfer: cleaning up

- Updated layer README.org to include prerequisites
- Removed unnecessary layer config variables which are mere re-naming
  of customization variables from `parinfer-rust-mode`.
- Removed the image.

 controls indentation based on parentheses or vice versa.
 
 ** Features:
-- Automatic management of parenthesis in clojure, emacs lisp, common-lisp and scheme following the parinfer editing paradigm.
+- Automatic management of parenthesis in Clojure, Emacs Lisp, Common Lisp and
+  Scheme following the parinfer editing paradigm.
 - Powered by a native library in the background
 
 * Install
+** Prerequisites
+- This layer requires =parinfer-rust= library being installed. See [[https://github.com/eraserhd/parinfer-rust#installing][here]] for the
+  dependencies.
+- The =parinfer-rust-mode= package requires Emacs compiled with dynamic module
+  support, which can be verified by existence of =MODULES= in the variable
+ =system-configuration-features=.
+- Currently, ony *nix system is supported.
+
+** Dotfile
 To use this configuration layer, add it to your =~/.spacemacs=. You will need to
 add =parinfer= to the existing =dotspacemacs-configuration-layers= list in this
 file.
 
-* Configuration
-This package comes preconfigured to auto install the native library in your cache
-directory. If this is not desired set the variables =parinfer-auto-download= to =nil=
-and set =parinfer-library= to the path of your local installation.
-This mode uses the new =smart-mode= instead of the =indent-mode= traditionally
-used with =parinfer=. For the autoinstallation =curl= is required to be in your
-path.
+#+BEGIN_SRC emacs-lisp
+  (setq-default dotspacemacs-configuration-layers '(pdf))
+#+END_SRC
 
-If you still want to manually configure it please check the respective package
-repo [[https://github.com/justinbarclay/parinfer-rust-mode][here]].
+* Configuration
+This package comes pre-configured to auto install the native library in your
+=spacemacs-cache-directory=. If you don't want this, see [[https://github.com/justinbarclay/parinfer-rust-mode#option-2-building-library-from-sources][here]] for a manual
+install option.
+
+=parinfer-rust-mode= operates under [[https://github.com/justinbarclay/parinfer-rust-mode#modes][three modes]]. By default, it starts in
+=smart-mode=, and can be toggled via =SPC t P=.
