Starting life with Linux

Today i started my life with Linux which is an open source OS . I chose Ubuntu linux.
First of all, i wanted to make my desktop a better one. So I used gnom-tweaktool for it.

by searching the internet, i found some codes for the job.



so, i opened terminal.
first i executed this code,

        sudo apt update

then i executed this code

       sudo apt upgrade


 actually i don't know exactly what the purpose of executing these codes.

after these codes , i had to execute these codes.

• sudo apt install gnom-shell-extensions
• sudo apt install gnom-tweak-tool

Then i logged into https://extensions.gnome.org/ site.
Then  there was an error on the top of the page. there was "click here to install browser extensions". So i clicked and installed that extension.

then again i opened my terminal and executed this code

• sudo apt install chrome-gnome-shell

 (actually i was using Firefox browser)

after these thing, i was able to install any extension  in https://extensions.gnome.org/ site. i just have to open the extension's page and press the toggle button
