</syntaxhighlight>'''Note 1''': this tutorial uses <code>cpx21</code> VM instance type which corresponds to an x86 architecture marchine with 3 CPU cores and 4GB of RAM, and <code>fsn1</code> location which corresponds to a data center in the city of Falkenstein in Germany. A list of all instance types can be obtained by running command <code>hcloud server-type list</code>, while a list of all locations can be obtained by running <code>hcloud location list</code> command. '''Note 2''': Hopefully, Hetzner Cloud team will support NixOS disk images soon, see [https://www.reddit.com/r/NixOS/comments/1desdbv/could_we_convince_hetzner_to_add_nixos_as_a/ Could we convince Hetzner to add Nixos as a standard image choice]. | </syntaxhighlight>'''Note 1''': this tutorial uses <code>cpx21</code> VM instance type which corresponds to an x86 architecture marchine with 3 CPU cores and 4GB of RAM, and <code>fsn1</code> location which corresponds to a data center in the city of Falkenstein in Germany.
