+## Additional configuration to improve your writing environment
+
+The last chapter shows you how small amount of configuration changes the look & feel of your Emacs -- I believe this is an important part of our writing system. In this section, I will introduce a little more of configuration I have done for myself. This section is also completely optional, and can be used for you to pick and choose ideas you find useful.
+
+![I am writing this guide using the very configuration](images/2020-06-23_23-00-07.png)
+
+To improve my own writing environment, I have made some changes to my Emacs as below. This has made my Emacs better for writing in Markdown files and looks a bit nicer (my subjective judgement):
+
+1. I have installed `markdown-mode` in order to help me write this very guide I am writing with this set up.
+
+2. I have made some changes to configuration in [`.emacs` at the commit before Part 2](https://github.com/nobiot/Zero-to-Emacs-and-Org-roam/blob/a3e74aaef1cebb7b80f44ed5aa6634c4837c4a90/.emacs) and provided explanation of these select changes below
+
+3. Updated packages. See the section below.
+
+### Get `M-x` to remember commands I have used
+
+You seem to call the same command again and again?
+
+Install a package called Smex. That's it. It works out-of-the-box with Ivy with no need for additional configuration.
+
+Now Emacs remembers the commands you have called, and list the immediate last one on top of the `M-x` list. 
+
+### Line spacing
+
+```
+;;; Line spacing, can be 0 for code and 1 or 2 for text
+(setq-default line-spacing 2)
+```
+
+The spacing is measured in pixels[^1]. 
+
+[^1]: Refer to the in-system manual via `C-h v line-spacing RET` -- this is a great way to discover things to help you personalise Emacs. 
+
+### Fixed-pitch fonts
+
+The font section of my .emacs now looks like this.
+
+```
+;; Font
+;;; If you want to know how to correct specify a font in Windows,
+;;; invoke `eval-last-sexp' for (w32-select-font)
+(set-face-attribute 'variable-pitch nil :font "iA Writer Quattro S-13")
+(set-face-attribute 'fixed-pitch nil :font "iA Writer Mono S-12")
+(set-face-attribute 'default nil :font "iA Writer Mono S-12")
+(set-fontset-font nil 'symbol (font-spec :family "Segoe UI Symbol" :size 11.0))
+(add-hook 'text-mode-hook 'variable-pitch-mode)
+```
+
+This way, when you are in Markdown or Org mode, you will get variable-pitch font, and fixed-pitch font when you are in programming mode or Helm buffer (e.g. to select a bibliographic entry to cite).
+
+### Stop Emacs from "littering" your folder with #file# and file~
+
+These configurations will stop Emacs creating backup files, etc. I find them annoying. Some of you may find them useful as backup files -- in this case, there is no problem keeping them. 
+
+```
+;; Avoid #file.org# to appear
+(auto-save-visited-mode)
+(setq create-lockfiles nil)
+;; Avoid filename.ext~ to appear
+(setq make-backup-files nil)
+```
+
+This one is handy when you are dealing with links and images in Markdown files, in addition to Emacs configuration. It highlights the pair of parentheses and brackets.
+
+```
+;; Turn on highlighting the pair of parenthesis when cursor is on one of the pair
+(show-paren-mode 1)
+```
+
+Refer to the [`.emacs` at the commit before Part 2](https://github.com/nobiot/Zero-to-Emacs-and-Org-roam/blob/a3e74aaef1cebb7b80f44ed5aa6634c4837c4a90/.emacs), and [its history](https://github.com/nobiot/Zero-to-Emacs-and-Org-roam/commit/a3e74aaef1cebb7b80f44ed5aa6634c4837c4a90#diff-1281e836e719f3cdc3750acfe4a4cf89) to see the incremental changes.

+# Part 2
+
+In Part 2, I will explore a new territory. I will be also learning along the way with you.
+
+I do not use Org-ref, nor Org-ref-bibtex. For my own notes, I use markdown files, and my own plug-in for Org-roam to support them ([Md-roam](https://github.com/nobiot/md-roam)). For bibliographic notes, instead of Org-ref, I just use `helm-bibtex` with customization for Pandoc Markdown format. 
+
+Having said this, I am making sure that I am building this guide as accurately as possible, while I configure and use the features I describe here. 
+
+You can judge the validity and usefulness of my guide from the outcome. All is open here in GitHub, so you can check what I am writing is correct or not. I will appreciate your feedback or correction.

 ## Set up Org-ref and Org-roam-bibtex (ORB)
 
 In this section, we will look at how to quickly set up ORB together with Org-ref to manage your bibliographic notes.
