 of targeting a specific GPU architecture. This can be used to get full
 desktop OpenGL support on devices that only support Vulkan.
 
+Features
+--------
+
+The feature-level of Zink depends on two things; what's implemented in Zink,
+as well as the features of the Vulkan driver.
+
+OpenGL 2.1
+^^^^^^^^^^
+
+OpenGL 2.1 is the minimum version Zink can support, and will always be
+exposed, given Vulkan support. There's a few features that are required
+for correct behavior, but not all of these are validated; instead you'll
+see rendering-issues and likely validation error, or even crashes.
+
+Here's a list of those requirements:
+
+* Vulkan 1.0
+* ``VkPhysicalDeviceFeatures``:
+
+  * ``logicOp``
+  * ``fillModeNonSolid``
+  * ``wideLines``
+  * ``largePoints``
+  * ``alphaToOne``
+  * ``shaderClipDistance``
+
+* ``VkPhysicalDeviceLimits``:
+
+  * ``maxClipDistances`` ≥ 6
+
+* Instance extensions:
+
+  * `VK_KHR_get_physical_device_properties2`_
+  * `VK_KHR_external_memory_capabilities`_
+
+* Device extensions:
+
+  * `VK_KHR_maintenance1`_
+  * `VK_KHR_external_memory`_
+
+OpenGL 3.0
+^^^^^^^^^^
+
+For OpenGL 3.0 support, the following additional device extensions are
+required to be exposed and fully supported:
+
+* `VK_EXT_transform_feedback`_
+* `VK_EXT_conditional_rendering`_
+
