+### Create dynamic array of integers
+
+```C
+DynamicArray dynamic_array;
+init_array(&dynamic_array);
+
+const int max_integers = 10;
+
+for (int i=0; i <= max_integers; i++) {
+    append_element(&dynamic_array, sizeof(int), (void*)&i);
+}
+
+// Don't forget to deallocate
+clear_array(&dynamic_array);
+```
+
+### Create two dimensional dynamic array of integers
+
+```C
+DynamicArray dynamic_array;
+init_array(&dynamic_array);
+
+DynamicArray sub_dynamic_array;
+const int max_sub_dyn_arrays = 10;
+
+for (int array_counter = 0; array_counter <= max_sub_dyn_arrays; array_counter++) {
+    init_array(&sub_dynamic_array);
+    append_element(&sub_dynamic_array, sizeof(int), (void*)&array_counter);
+    append_element(&dynamic_array, sizeof(DynamicArray), (void*)&sub_dynamic_array);
+}
+
+// Don't forget to deallocate
+clear_array(&dynamic_array);
