How to Install Estonian ID card

Installing Estonian ID card support software in Arch is pretty tricky. You need the following packages (in approximately this order):

pcsclite [1]
ccid [2]
openct [3]
opensc, preferably the modified version. Get it from here: [4]

Since most of the packages in AUR were horribly outdated, I ended up updating the packages. Difficult for me, easy for you. After that simply follow the instructions at [5] to make Firefox know about the ID-card.
