+# Cucumber and JRuby limitations
+
+`cucumber` can be executed on `JRuby` (tested with `9.2`), although some of the features
+are not available on this platform.
+
+## Defining steps with native languages
+
+There are currently three languages (Russian, Ukrainian and Uzbek) for which the step definition
+can not be written in native language.
+That means, for example, that you can not write the following code:
+
+```ruby
+Допустим('я ввожу число {int}') do |число|
+  calc.push число
+end
+```
+
+Instead, you have to write:
+```ruby
+Given('я ввожу число {int}') do |number|
+  calc.push number
+end
+```
+
+Of course, you can still write your feature files in a native language, for example, the following
+feature file can be executed on JRuby:
+
+```gherkin
+# language: ru
+Функционал: Сложение чисел
+  Чтобы не складывать в уме
+  Все, у кого с этим туго
+  Хотят автоматическое сложение целых чисел
+
+  Сценарий: Сложение двух целых чисел
+    Допустим я ввожу число 50
+    И затем ввожу число 70
+    Если я нажимаю "+"
+    То результатом должно быть число 120
+```
