+### Strongly typed handles
+
+Each Vulkan handle type is exposed as a newtyped struct for improved type safety. Null handles can be constructed with
+`T::null()`, and handles may be freely converted to and from `u64` with `Handle::from_raw` and `Handle::as_raw` for
+interop with non-Ash Vulkan code.

 ### Default implementation for all types

-*Note*: No validation is done, the lifetimes only have to live as long as the builder object. It is the responsibility of the user to make sure that the pointers are valid.
+
+Builders implement `Deref` targeting their corresponding Vulkan struct, so references to builders can be passed directly
+to Vulkan functions. This is encouraged as doing so allows Rust to check the lifetimes of captured objects are valid,
+whereas calling `build` discards lifetime information, making inadvertent use-after-free errors more likely.

-### Interop
-Vulkan objects inside Ash can be constructed from raw values with `Object::from:raw`. Useful if you need to interact with a C library.

-PipelineBindPoint::from_raw(bindpoint);

 ### Function pointer loading
 Ash also takes care of loading the function pointers. Function pointers are split into 3 categories.
