 Помощь в обработке клиентских заявок путем поиска продукции РЕХАУ по запросу, выраженному в свободной форме, и в работе с прайс-листом BS РЕХАУ
 
 ## Реализованные функции
-- Поиск артикула с помощью `=RHSOLUTIONS()`
 - Экспорт массива ячеек вида "Артикул - Количество" в прайс-лист
 - Актуализация прайс-листа до последней версии
 - Объединение нескольких прайс-листов в один файл
-    - Сложением всех позиций по артикулам
-    - С разнесением данных по колонкам в конечном файле
+- Поиск пар артикул-количество в любой сторонней таблице и экспорт в таблицу заказов
+- Подбор монтажных гильз для фитингов RAUTITAN
+- Подбор ремонтных муфт по количеству трубы
+- Экспорт таблицы заказов в девятиграфку по ГОСТ
 
 *Для работы функций "Экспорт", "Актуализация" и "Объединение" требуется указать путь к файлу пустого прайс-листа РЕХАУ*
 
+## Реализованные формулы для работы с артикулами
+- ```=РЕХАУ()``` - поиск артикула РЕХАУ по произвольному запросу в сервисе [RhSolutions-Api](https://gitea.cebotari.ru/chebser/RhSolutions-Api) 
+- ```=РЕХАУАРТИКУЛ()``` - экстракция артикула РЕХАУ из любой строки по регулярному выражению
+- ```=РЕХАУИМЯ()``` - поиск названия артикула по номеру
+- ```=РЕХАУЦЕНА()``` - поиск цены в евро по номеру артикула
+- ```=РЕХАУЦЕНАРУБ()``` - поиск цены в рублях по номеру артикула и курсу ЦБ на любую дату
+- ```=КУРСЕВРО()``` - курс евро ЦБ на дату
+
 ## Установка
 1. Скопировать файл плагина в папку 
 ```
