Congratulations on the translation!

The preferred format (see CONTRIBUTING) for multiple formats is
* [Another Awesome Book](http://example.com/) - John Doe (HTML) [(PDF, EPUB)](https://downloads.example.org/book.html)

Links should be to the resource, not the author/translator.

For a translated work, the "author" should be the original author, not the translator. Though I don't see other cases where we list the translator, translators deserve credit, so [title](link) - Karl Seguin, Umut Işık tarafından çevirildi would be appropriate.

Updated the PR accordingly.
