**Installing Vivaldi Browser on Gentoo Linux**

Gentoo is a source-based distribution that allows for precise control over the installation process. Here's a step-by-step guide to installing Vivaldi browser on Gentoo:

A working Gentoo Linux installation
Root privileges (`sudo` or `su`)
Internet connection

Before installing Vivaldi, update the package list to ensure you have access to the latest packages:

sudo emerge --update --deep gentoo-release

This command updates the Gentoo repository and downloads any available updates.

Vivaldi is not included in the default Gentoo repositories. We'll install the required packages manually:

sudo emerge dev-util/qt5

sudo emerge net/www/html5lib

sudo emerge dev-libs/libxml2

Now that we have the required packages installed, we can proceed with installing Vivaldi:

sudo emerge -c --ask www-vivaldi

This command installs Vivaldi and its dependencies.
