Disclaimer* I am completely new to everything that I have been working on the last couple of days so I need detailed instructions please.

I would like someone to explain to me step by step how to use hg19 as a reference genome in galaxy. I figured out how to download and convert the hg19.2bit file from ucsc, but I am stuck now. I can see the hg19.fa file in virtualbox terminal, but I have no idea what to do next as to extracting the file onto my computer or doing something completely different to get the file into galaxy.

I would appreciate any help! I have been researching extensively online, but I have ultimately decided to post here since I have no other options.
