+## Getting Started
+
+Here's an example for creating a 128x128 array of OpenSimplex2 noise
+
+```c
+// Create and configure noise state
+FnlState noise = fnl::createState();
+noise.noise_type = OPENSIMPLEX2;
+
+// Gather noise data
+float* noise_data = malloc(128 * 128 * float::size);
+int index = 0;
+
+for (int y = 0; y < 128; y++)
+{
+    for (int x = 0; x < 128; x++) 
+    {
+        noise_data[index++] = fnl::getNoise2D(&noise, x, y);
+    }
+}
+
+// Do something with this data...
+
+// Free data later
+free(noise_data);
+```
