-## Setup
+## Setup for Linux user
 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
+- `espeak` for reading a given massage aloud
 
 ```bash
-$ sudo apt install libnotify-bin alsa-utils mailutils heirloom-mailx bsd-mailx

-Recipient e-mail address is saved at /path/to/.julia/v0.6/Notifier/email/address.txt.
