 ```shell

+echo "Server = https://download.opensuse.org/repositories/home:/CZ-NIC:/dns-probe/Arch/$(uname -m)" | sudo tee -a /etc/pacman.conf
 
-Now you need to update the repository list and then you can finally install the C-DNS library:
+key=$(curl -fsSL https://download.opensuse.org/repositories/home:/CZ-NIC:/dns-probe/Arch/$(uname -m)/home_CZ-NIC_dns-probe_Arch.key)
+fingerprint=$(gpg --quiet --with-colons --import-options show-only --import --fingerprint <<< "${key}" | awk -F: '$1 == "fpr" { print $10 }')
 
-```shell
-sudo apt-get update
-sudo apt-get install libcdns1 libcdns-dev
-```
+sudo pacman-key --init
+sudo pacman-key --add - <<< "${key}"
+sudo pacman-key --lsign-key "${fingerprint}"
 
-The C-DNS library is separated into two packages. `libcdns1` package installs the shared library and `libcdns-dev` package installs
-development headers.
+sudo pacman -Sy home_CZ-NIC_dns-probe_Arch/c-dns
+```
