which file should I download ? because according to your instructions

Now inside of the folder which the client writes and reads the blockchain data to we'll download a copy of it here: wget http://einfachmalnettsein.de/steem-blocks-and-index.zip
(File is ~1.9GB - May take a few minutes)

After the blockchain downloads we can extract the contents with the following command:
unzip -o steem-blocks-and-index.zip
(may take a minute or two)

Sorry for my noobness as my proficiency in ubuntu is lacking, I just want to try get this up and running.
