# How to use: (assuming you check out stuff in ~/src)
#
# 0. Make sure to have a clean working tree
#
# 1. Download the Material Design icon set:
#       $ cd ~/src
#       $ git clone https://github.com/Templarian/MaterialDesign.git
#
# 2. Go to the icon source directory:
#       $ cd ~/src/keepassxc/share/icons
#
# 3. Create the icons:
#       $ bash ../../utils/makeicons.sh ~/src/MaterialDesign
#
# 4. Re-build and run KeePassXC:
#       $ cd ~/keepassxc/build
#       $ make keepassxc && src/keepassxc
#
# Material icons: https://materialdesignicons.com/
