+## Class Timer
+
+**To use this class, you need to put `#define _pthread` before your `#include "ovo.h"` **
+**And also, use `g++ yourCode.cpp -std=c++14 -pthread` to compile**
+---------
+### Timer.setTimeout()
+This can let your be executed after certain time.
+#### Params:
+ - **auto function** Your function. `Lambda Expression is allowed!`
+ - **int delay** Time to delay in milliseconds.
+
+#### Example
+````C++
+#include <iostream>
+#include <string>
+
+#define _pthread
+
+#include "ovo.h"
+
+using namespace std;
+
+void display(){
+    cout << "Hey.. After 1s." << endl;
+}
+
+int main()
+{
+    ovo::Timer t = ovo::Timer();
+    t.setsetTimeout(dis, 1000); 
+
+    while (1); //Keep the main thread never stop
+    return 0;
+}
+````
+This will get the following result. (Use Ctrl+C to interrupt)
+>Hey.. After 1s.
