+using Nure.NET;
+using Nure.NET.Types;
+
+class Program
+{
+    static void Main()
+    {
+        var teachers = Cist.GetTeachers();
+        
+        foreach (var teacher in teachers)
+        {
+            Console.WriteLine(teacher.FullName);
+        }
+    }
+}
+```
+Get groups list:
+```csharp
+using Nure.NET;
+using Nure.NET.Types;
+
+class Program
+{
+    static void Main()
+    {
+        var groups = Cist.GetGroups();
+        
+        foreach (var group in groups)
+        {
+            Console.WriteLine(group.Name);
+        }
+    }
+}
+```
+Get auditories list:
+```csharp
+using Nure.NET;
+using Nure.NET.Types;
+

+        
+        foreach (var auditory in auditories)
+        {
+            Console.WriteLine(auditory.Name);
+        }
+    }
+}
+```
+Get schedule for group or other entity:
+```csharp
+using Nure.NET;
+using Nure.NET.Types;
+
+class Program
+{
+    static void Main()
+    {
+        /* Get schedule for group "КІУКІ-22-7", for other entities use EntityType enum
+            * EntityType.Group - for groups
+            * EntityType.Teacher - for teachers
+            * EntityType.Auditory - for auditories
+           Default, if you don't specify startTime and endTime, method will return 
+           all avilable lessons for that group.
+        */
+        var schedule = Cist.GetEvents(10304333, EntityType.Group);
+        
+        foreach (var lesson in schedule)
+        {
+            Console.WriteLine(lesson);
+        }

+using Nure.NET;
+using Nure.NET.Types;
+
+class Program
+{
+    static void Main()
+    {
+        var events = Cist.GetEvents(EventType.Group, 10304333, 1693170000, 1694811599);
+
+        foreach (var item in events)
