 ### Доработка
 
-Исправление ошибок приветствуется, технические детали можно выяснить в [чате](https://gitter.im/Flexberry/PlatformDevelopment) или непосредственно в описании Issue.
+Исправление ошибок приветствуется, технические детали можно выяснить в [чате](https://t.me/flexberry) или непосредственно в описании Issue.
 Добавление новой функциональности рекомендуется согласовывать с авторами, поскольку принятие Pool Request в этом случае может быть затруднено.
