Firstly, you must have git
and svn
installed.
sudo apt install curl git subversion wget
We replace Git for SVN and recommend strongly SVN, which is quicker like a Millennium Falcon than Git.
# If the folder icons doesn't exist
mkdir ~/.local/share/icons
# Download quickly like a Millennium Falcon
svn export https://github.com/Magog64/SURU-PLUS/trunk/ ~/.local/share/icons/Suru++
# To update the next latest changes and to overwrite
svn export --force https://github.com/Magog64/SURU-PLUS/trunk/ ~/.local/share/icons/Suru++
