 ### 2. Now you can get log from static List everywhere
-     
+
     var logList = MemoryLogger.LogList;
 
 Since v2.0.0 you can get log for concrete LogLevel:
 
     var warnLog = MemoryLogger.GetLog(LogLevel.Warning);
 
+
+### 3. Clean logs
+
+    MemoryLogger.ClearAllLogs();
+Or
+
+    MemoryLogger.ClearLogLevel(LogLevel.Information);
+    MemoryLogger.ClearLogLevel(LogLevel.Debug);
