 ### Основные функции
 
-#### Переключение контекста Kubernetes
-Быстрое переключение между различными Kubernetes кластерами/контекстами:
+#### Управление контекстами Kubernetes
+Полное управление Kubernetes контекстами/кластерами:
+
+**Просмотр и переключение:**
 - Просмотр всех доступных контекстов в виде таблицы
 - Отображение текущего активного контекста (✓)
 - Переключение на другой контекст
 - Автоматическая переинициализация подключения к новому кластеру
 - После переключения контекста namespace сбрасывается и нужно выбрать заново
 
+**Добавление нового контекста:**
+- Интерактивное создание нового контекста
+- Указание имени контекста, кластера, пользователя
+- API server URL
+- Опционально: токен аутентификации
+- Опционально: сертификат CA (base64)
+- Автоматическое создание резервной копии kubeconfig перед изменением
+
+**Удаление контекста:**
+- Удаление ненужных контекстов
+- Защита от удаления текущего активного контекста
+- Автоматическое создание резервной копии kubeconfig
+
 #### Выбор Namespace
 Выберите namespace для работы. Все последующие операции будут выполняться в выбранном namespace.
