+
+Vulkan/GL/GLES/EGL/GLX/WGL Loader-Generator based on the official specifications
+for multiple languages.
+
+Check out the [webservice for glad2](https://glad.sh) to generate the files you need!
+
+
+**NOTE:** This is the 2.0 branch, which adds more functionality but changes the API.
+
+Some languages are only available in the [glad1 generator](https://glad.dav1d.de).
+
+## Examples
+
+```c
+#include <glad/gl.h>
+// GLFW (include after glad)
+#include <GLFW/glfw3.h>
+
+
+int main() {
+    // -- snip --
+
+    GLFWwindow* window = glfwCreateWindow(WIDTH, HEIGHT, "LearnOpenGL", NULL, NULL);
+    glfwMakeContextCurrent(window);
+
+    int version = gladLoadGL(glfwGetProcAddress);
+    if (version == 0) {
+        printf("Failed to initialize OpenGL context\n");
+        return -1;
+    }
+
+    // Successfully loaded OpenGL
+    printf("Loaded OpenGL %d.%d\n", GLAD_VERSION_MAJOR(version), GLAD_VERSION_MINOR(version));
+
+    // -- snip --
+}
+```
