+# Nazara Imgui
+
+Nazara Imgui is a [Nazara Engine](https://github.com/NazaraEngine/NazaraEngine) module that integrates [Imgui](https://github.com/ocornut/imgui) features into the Engine.
+
+You can use it in any kind of commercial and non-commercial applications without any restriction ([MIT license](http://opensource.org/licenses/MIT)).

+## How to Use
+
+```
+// Add NazaraImgui.hpp to your includes
+#include <NazaraImgui/NazaraImgui.hpp>
+
+// main.cpp
+{
+    // Add Nz::Imgui to the modules list
+    Nz::Modules<Nz::Graphics, Nz::Imgui,...> nazara;
+
+    // Create and init renderwindow
+    Nz::RenderWindow window;
+
+
+    // Once window is created, init Imgui instance
+    // This will load shaders, create graphic pipeline, install event handlers, ...
+    Nz::Imgui::Instance()->Init(window);
+
+    // [...]
+    float value = 0.f; // for ImGui::SliderFloat
+    float color[] = { 1,0,0,1 }; // for ImGui::ColorPicker4
+
+    // for ImGui::Image
+    Nz::TextureParams texParams;
+    texParams.renderDevice = device;
+    texParams.loadFormat = Nz::PixelFormat::RGBA8;
+    std::shared_ptr<Nz::Texture> logo = Nz::Texture::LoadFromFile("MyImage.png", texParams);
+
+    Nz::Clock updateClock;
+    while(window.IsOpen())
+    {
+        // ProcessEvent will send events to imgui
+        window.ProcessEvents();
+
+        Nz::RenderFrame frame = window.AcquireFrame();
+        if (!frame)
+        {
+            std::this_thread::sleep_for(std::chrono::milliseconds(1));
+            continue;
+        }
+
+        // Call update on the instance
+        Nz::Imgui::Instance()->Update(window, updateClock.GetSeconds());
+
+        // Then use standard imgui functions
+        ImGui::Begin("MyWindow");
+
+        ImGui::SliderFloat("Value", &value, 0, 10);
+        
+        // display a Nz::Texture
+        ImGui::Image(logo.get());
+
+        ImGui::ColorPicker4("Color", color, ImGuiColorEditFlags_PickerHueWheel | ImGuiColorEditFlags_DisplayRGB);
+        
+        ImGui::End();
+
+        // Before presenting frame, render imgui
+        Nz::Imgui::Instance()->Render(window, frame);
+        frame.Present();
+
+        updateClock.Restart();
+    }
