How to install latest?

[erikmueller]

Maybe I'm just too dumb but I'm having problems to install this package.
Here's what happens:

1. Npm says the newest version is 0.3.0 (published a year ago)
2. When referencing the master branch I'm basically lacking ALL src files and just get an index.js, requireing the (also not available) dist folder.

Am I missing something? Would really like to have the extensions fix.
