+## Swapchain
+
+### Swapchain Overview
+
+This layer is a work in progress. DeviceLimits layer is intended to capture two broad categories of errors:
+ 1. Incorrect use of APIs to query device capabilities
+ 2. Attempt to use API functionality beyond the capability of the underlying device
+
+For the first category, the layer tracks which calls are made and flags errors if calls are excluded that should not be, or if call sequencing is incorrect. An example is an app that assumes attempts to Query and use queues without ever having called vkGetPhysicalDeviceQueueFamilyProperties(). Also, if an app is calling vkGetPhysicalDeviceQueueFamilyProperties() to retrieve properties with some assumed count for array size instead of first calling vkGetPhysicalDeviceQueueFamilyProperties() w/ a NULL pQueueFamilyProperties parameter in order to query the actual count.
+For the second category of errors, DeviceLimits stores its own internal record of underlying device capabilities and flags errors if requests are made beyond those limits. Most (all?) of the limits are queried via vkGetPhysicalDevice* calls.
+

+
+### Swapchain Pending Work
+Additional checks to be added to Swapchain
+
+ 1. Check that the queue used for presenting was checked/valid during vkGetPhysicalDeviceSurfaceSupportKHR.
+ 2. One issue that has already come up is correct UsageFlags for WSI SwapChains and SurfaceProperties.
+ 3. Tons of other stuff including semaphore and synchronization validation.
+
+
## General Pending Work
A place to capture general validation work to be done. This includes new checks that don't clearly fit into the above layers.
