Your GitHub README looks reasonably good. This is likely going to be successful. The website has some issues. The download page displays empty dropdowns on the left-hand side of the download buttons, for instance (I'm on a Mac).
You might want to fix all "WTFs" on the main user journey before posting your links as successful links cannot be reposted for a year or so. (And getting that success again becomes harder once you've had attention here.)
If you consider posting a direct link to your website, make sure it can handle the peak load. HN loads can be brutal.
