Usage:  
-clone repo into empty directory  
-mkdir data  
-mkdir data/samples_raw  
-mkdir data/samples_raw/{sample_name}  
-for each sample, place the fastqs for  
 that sample in data/samples_raw/{sample_name}/  
-specify path to reference genome in workflow/config/config.yaml  

-run with 'snakemake --use-conda'
