 As with many other open-source projects, this one is also maintained by its author in his free time. Any help in making Traditional T9 better will be highly appreciated. Here is how:
 - Add [a new language](CONTRIBUTING.md#adding-a-new-language), [new UI translations](CONTRIBUTING.md#translating-the-ui) or simply fix a spelling mistake. The process is very simple and even with minimum technical knowledge, your skills as a native speaker will be of great use. Or, if you are not tech-savvy, just [open a new issue](https://github.com/sspanak/tt9/issues) and put the correct translations or words there. Correcting misspelled words or adding new ones is the best you can do to help. Processing millions of words in multiple languages is a very difficult task for a single person.
 - Share your list of added words. Use the Export function in Settings → Languages → Added Words and upload the generated CSV file in a [new issue](https://github.com/sspanak/tt9/issues). You are also welcome to [open a PR](https://github.com/sspanak/tt9/pulls) if you have good technical knowledge and can split them by language.
-- [Report bugs](https://github.com/sspanak/tt9/issues) or other unusual behavior on different phones. It is only possible to verify correct operation and compatibility on [a handful of phones](#%EF%B8%8F-compatibility), but Android behavior and appearance vary a lot across the millions of devices available out there.
