+Vorbis Decoding
+===============
+Vorbis decoding is enabled via stb_vorbis. To use it, you need to include the header section of stb_vorbis
+before the implementation of miniaudio. You can enable Vorbis by doing the following:
+
+```c
+#define STB_VORBIS_HEADER_ONLY
+#include "extras/stb_vorbis.c"    /* Enables Vorbis decoding. */
+
+#define MINIAUDIO_IMPLEMENTATION
+#include "miniaudio.h"
+
+/* stb_vorbis implementation must come after the implementation of miniaudio. */
+#undef STB_VORBIS_HEADER_ONLY
+#include "extras/stb_vorbis.c"
+```
