Note: Keep in mind that the owner of the key may distribute updates, packages and repositories that your system will trust (more information).
In a console enter:
echo 'deb http://download.opensuse.org/repositories/home:/thindil/Debian_11/ /' | sudo tee /etc/apt/sources.list.d/home:thindil.list curl -fsSL https://download.opensuse.org/repositories/home:thindil/Debian_11/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/home_thindil.gpg > /dev/null sudo apt update
You can also skip this step and download the selected package(s) directory, but then you will not have option to obtain automatically updates to them.
The same detailed information about how to install each package you can find at download page of the package. For example, for yass.
