Hi, I copied in my markdown content from
http://source.dabase.branchable.com/?p=source.git;a=tree;f=blog; to a hugo
template:
https://github.com/zeit/now-examples/tree/master/static-hugo/content/post and
now I see:

Little confused. So I hope you can excuse the newbie questions:
* Does hugo understand my .mdwn extensions or do I need to rename the files?
* Does hugo use the time from the git commits of the markdown files I committed?
* How do I maintain the previous URL structure? e.g. http://dabase.com/blog/DevOps_evolution/

Thank you in advance!
