Run secondcrack in a nginx server

I am trying to run secondcrack https://github.com/marcoarment/secondcrack that is a php solution to A static-file Markdown blogging engine in a nginx server (the original was only tested in Apache). So does anybody know how to convert this Apaches's .htaccess to nginx syntax?

Options -MultiViews

AddOutputFilterByType DEFLATE text/html text/plain text/css text/javascript text/xml text/rss text/rss+xml

RewriteRule ^([^\.]*)$ - [T=text/html]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME}.html -f
