+# GTKMM
+
+## About
+
+[**gtkmm**](https://www.gtkmm.org/) is the official C++ interface for GTK. Highlights include typesafe 
callbacks, and a comprehensive set of widgets that are easily extensible via inheritance. You can create user 
interfaces either in code or with the [Glade User Interface designer](http://glade.gnome.org/), using 
Gtk::Builder. There's [extensive documentation](https://www.gtkmm.org/en/documentation.shtml), including API 
reference and a tutorial.
+
+gtkmm is free software distributed under the GNU Library General Public License (LGPL).
+
+## Releases
+
+gtkmm follows the official GNOME Platform Bindings release schedule. This guarantees API/ABI-stability and 
new releases on a predictable schedule, delivering C++ API for the underlying GTK+ and GNOME APIs as soon as 
possible.
+
+## gtk-rs Documentation
+
+There is an official [gtkmm API Documentation](https://www.gtkmm.org/en/documentation.html) for using GTK 
and C++ together provided on the gtkmm website.
+
+## A Hello World app
+
+```cpp
+// File: helloworld.h
+
+#ifndef GTKMM_EXAMPLE_HELLOWORLD_H
+#define GTKMM_EXAMPLE_HELLOWORLD_H
+
+#include <gtkmm/button.h>
+#include <gtkmm/window.h>
+
+class HelloWorld : public Gtk::Window
+{
+
+public:
+  HelloWorld();
+  virtual ~HelloWorld();
+
+protected:
+  //Signal handlers:
+  void on_button_clicked();
+
+  //Member widgets:
+  Gtk::Button m_button;
+};
+
+#endif
+```
+
+```cpp
+// File: helloworld.cc
+
+#include "helloworld.h"
+#include <iostream>
+
+HelloWorld::HelloWorld()
+: m_button("Hello World")   // creates a new button with label "Hello World".
+{
+  // Sets the border width of the window.
+  set_border_width(10);
+
+  // When the button receives the "clicked" signal, it will call the
+  // on_button_clicked() method defined below.
+  m_button.signal_clicked().connect(sigc::mem_fun(*this,
+              &HelloWorld::on_button_clicked));
+
+  // This packs the button into the Window (a container).
+  add(m_button);
+
+  // The final step is to display this newly created widget...
+  m_button.show();
+}
+
+HelloWorld::~HelloWorld()
+{
+}
+
+void HelloWorld::on_button_clicked()
+{
+  std::cout << "Hello World" << std::endl;
+}
+```
+
+```cpp
+// File: main.cc
+
+#include "helloworld.h"
+#include <gtkmm/application.h>
+
+int main (int argc, char *argv[])
+{
+  auto app = Gtk::Application::create(argc, argv, "org.gtkmm.example");
+
+  HelloWorld helloworld;
+
+  //Shows the window and returns when it is closed.
+  return app->run(helloworld);
+}
+```
+
+### Output
+
+After compiling and run the above code and you should see get the below given output:
+
+![gtkmm output for a hello world application](/assets/img/docs/docs-cpp-helloworld.png)
+
+### Explanation
+
+This code depicts how to use GTK C++ binding for creating a simple Hello World application. A more detailed 
explanation of the above code can be checked out 
[here](https://developer.gnome.org/gtkmm-tutorial/stable/sec-helloworld.html.en).

+# GTK and Rust
+
+## About
+
+[**gtk-rs**](https://gtk-rs.org/) project deals with the Rust bindings for GTK, Cairo, GtkSourceView and 
other GLib-compatible libraries.
+
+## gtk-rs Documentation
+
+There is an official [gtk-rs API Documentation](https://gtk-rs.org/docs/gtk/) for using GTK and Rust 
together.
+
+There are also a growing number of examples and thorough tests of language features in the test suite.
+
+## A Hello World app
+
+```rust
+extern crate gtk;
+use gtk::prelude::*;
+use gtk::{ButtonsType, DialogFlags, MessageType, MessageDialog, Window};
+
+fn main() {
+    if gtk::init().is_err() {
+        println!("Failed to initialize GTK.");
+        return;
+    }
+    MessageDialog::new(None::<&Window>,
+                      DialogFlags::empty(),
+                      MessageType::Info,
+                      ButtonsType::Ok,
+                      "Hello World").run();
+}
+```
+
+### Explanation
+
+This code depicts how to use GTK Rust binding for creating a simple Hello World application.
+
+## Tutorials
+
+[**gtk-rs**](https://gtk-rs.org/) website lists various [tutorials](https://gtk-rs.org/docs-src/tutorial/) 
that range from introduction to the usage of Gtk-rs crates and much more. If you want more tutorials please 
refer to the [FAQ](https://gtk-rs.org/docs-src/faq) page on the gtk-rs website.
