 ### Translators!
 If you want to see this app translated to your language, go grab [this file](https://github.com/developersu/ns-usbloader/blob/master/src/main/resources/locale.properties) and translate it.
-Upload somewhere (create PR, use pastebin/google drive/whatever else). [Create new issue](https://github.com/developersu/ns-usbloader/issues) and post a link. I'll grab it and add.

 #### TODO (maybe):
 - [x] [Android support](https://github.com/developersu/ns-usbloader-mobile)
 - [ ] File order sort (non-critical)
 - [ ] More deep file analyze before uploading.
