 # Linux OS
 ## Setup
 Before using Notifier.jl, you need to install following softwares in your Linux system.
-- "libnotify" for a desktop notification
-- "mail" for an e-mail notification
-- "aplay" (Advanced Linux Sound Architecture) for a sound notification
+- `libnotify` for a desktop notification
+- `mail` for an e-mail notification
+- `aplay` (Advanced Linux Sound Architecture) for a sound notification
 
 ```bash
-sudo apt install libnotify-bin alsa-utils mailutils heirloom-mailx bsd-mailx
+$ sudo apt install libnotify-bin alsa-utils mailutils heirloom-mailx bsd-mailx
 ```
 
-This package uses "mail" linux command to notify by e-mail. Thus you need some settings in advance.
