+Disclaimer
+----------
+
+Mesa implements various APIs, including `OpenGL`_, `OpenGL ES`_,
+`Vulkan`_ and `OpenCL`_. Even though Mesa implements these APIs, the
+implementation isn't formally conformant on all combinations of drivers
+and hardware. `Khronos`_ maintains lists of conformant implementations
+for each of their APIs, as well as `trademark details`_.
+
+Please do not refer to the library as *MesaGL* (for legal reasons). It's
+just *Mesa* or *The Mesa 3-D graphics library*.
