  See [table](http://www.loc.gov/standards/iso639-2/php/code_list.php) (ISO 639-1 Code) for available codes.
 5. When you are ready, use `Export JPT` button to export modified strings to an archive (.jpt extension)
 6. Send that archive to us, you can use either 
- - Issue tracker (preffered) - Search for an issue with title `Translation: xxxx`, create new if it does not exist
+ - Issue tracker (preferred) - Search for an issue with title `Translation: xxxx`, create new if it does not exist
  - or e-mail it to `jindra.petrik@gmail.com`
 7. There's no need to translate everything. Some resource packs are HUGE (like `docs/pcode/AS3`) and generally not needed.
  For `AdvancedSettingDialog` you don't need to translate config descriptions (`config.description.*` keys).
