 ## Install NTP server
 
 To begin, we need to install NTP server. You can do so by [opening a command line terminal](https://linuxconfig.org/how-to-open-a-terminal-on-ubuntu-xenial-xerus-16-04-linux) and entering the following command:
 
 ```
-$ sudo apt update
-$ sudo apt install ntp
+sudo apt update
+sudo apt install ntp
 ```
 
 ## Configure NTP server
 
 The NTP server comes pre-configured with some server pools already, which you can see inside the `/etc/ntp.conf` file.
 
 ```
-$ cat /etc/ntp.conf
+cat /etc/ntp.conf
 ```
