 ### Contributing
 
-Feel free to ask for new rules for languages that is not already here.
+We really appreciate if you report bugs and errors in the transliteration, especially if you are a native speaker of
+the language and question. Feel free to ask for additional languages in the issues, but please not that the
+maintainer of this repository does not speak all languages. If you can provide a Pull Request with rules for
+a new language or extend the rules for an existing language that would be amazing.
 
-All you need to do is:
+To add a new language you need to:
 
-1. Provide transliteration rules for your language, in any form, e.g. `'ї' => 'ji'`
-2. Provide some examples of texts transliterated with this rules e.g. `'Україна' => 'Ukrajina'`
+1. Create a `[language].json` in `Resources/rules`
+2. If you believe the language should be a default ruleset you can add the language to 
+`Cocur\Slugify\Slugify::$options`. If you add the language there all existing tests still have to pass
+3. Run `php bin/generate-default.php`
+4. Add tests for the language in `tests/SlugifyTest.php`. If the language is in the default ruleset add your
+test cases to `defaultRuleProvider()`, otherwise to `customRulesProvider()`.
+
+Submit PR. Thank you very much.
