### Required Reading

If you are unable to boot your device, please look for the section relevant to you and follow the instructions.

If you still cannot solve your issue and need to reach out for help, please paste the contents of all relevant .log files from the root of your SD card into a [Gist](https://gist.github.com/), then come for help prepared with a detailed description of your problem and what you've tried.

To use the [magnet](https://en.wikipedia.org/wiki/Magnet_URI_scheme) links on this page, you will need a torrent client like [Deluge](http://dev.deluge-torrent.org/wiki/Download).
