+In an effort to make Vulkan synchronization more accessible, this library provides an efficient simplification of core synchronization mechanisms such as pipeline barriers and events.
 
 Rather than the complex maze of enums and bit flags in Vulkan - many combinations of which are invalid or nonsensical - this library collapses this to a much shorter list of ~40 distinct usage types, and a couple of options for handling image layouts.

 Use of other synchronization mechanisms such as semaphores, fences and render passes are not addressed in this library at present.
 
+## Bindings
+
+There are a number of Vulkan ffi bindings available, and I do plan to support the most common bindings, but for now this library only implements support for [`ash`](https://crates.io/crates/ash). Please add other bindings you need via a pull-request; I would happily accept it.
+
+## Expressiveness
+
+Despite the fact that this library is fairly simple, it expresses 99% of what you'd actually ever want to do in practice. Adding the missing expressiveness would result in increased complexity which does not seem worth the trade-off. If you have any pattern you need express, please file an issue!
+
+Here's a list of known things you cannot express:
+
+* Execution only dependencies cannot be expressed. These are occasionally useful in conjunction with semaphores, or when trying to be clever with scheduling - but their usage is both limited and fairly tricky to get right anyway.
+
+* Depth/Stencil Input Attachments can be read in a shader using either `ImageLayout::ShaderReadOnlyOptimal` or `ImageLayout::DepthStencilReadOnlyOptimal` - this library always uses `ImageLayout::DepthStencilReadOnlyOptimal`. It is possible (though highly unlikely) when aliasing images that this results in unnecessary transitions.
