 This is the core crate for the Dioxus Virtual DOM. This README will focus on the technical design and layout of this Virtual DOM implementation. If you want to read more about using Dioxus, then check out the Dioxus crate, documentation, and website.

 ## Internals

 - React: hooks, concurrency, suspense
 - Dodrio: bump allocation, double buffering, and some diffing architecture
-- Percy: html! macro architecture, platform-agnostic edits
-- InfernoJS: approach to keyed diffing
-- Preact: approach for normalization and ref
-- Yew: passion and inspiration ❤️
 
 Dioxus-core leverages some really cool techniques and hits a very high level of parity with mature frameworks. However, Dioxus also brings some new unique features:
 
 - managed lifetimes for borrowed data
-- suspended nodes (task/fiber endpoints) for asynchronous vnodes
+- placeholder approach for suspended vnodes
+- fiber/interruptible diffing algorithm
 - custom memory allocator for vnodes and all text content
 - support for fragments w/ lazy normalization
 - slab allocator for scopes
 - mirrored-slab approach for remote vdoms
+- dedicated subtrees for rendering into separate contexts from the same app
 
-There's certainly more to the story, but these optimizations make Dioxus memory use and allocation count extremely minimal. For an average application, it is possible that zero allocations will need to be performed once the app has been mounted. Only when new components are added to the dom will allocations occur - and only en mass. The space of old VNodes is dynamically recycled as new nodes are added. Additionally, Dioxus tracks the average memory footprint of previous components to estimate how much memory allocate for future components.

-All in all, Dioxus treats memory as an incredibly valuable resource. Combined with the memory-efficient footprint of Wasm compilation, Dioxus apps can scale to thousands of components and still stay snappy and respect your RAM usage.

+The final implementation of Dioxus must:
 
 - Be **fast**. Allocators are typically slow in Wasm/Rust, so we should have a smart way of allocating.
-- Be extremely memory efficient. Servers should handle tens of thousands of simultaneous VDoms with no problem.
-- Be concurrent. Components should be able to pause rendering using a threading mechanism.
-- Be "remote". Edit lists should be separate from the Renderer implementation.
-- Support SSR. VNodes should render to a string that can be served via a web server.
+- Be memory efficient. Servers should handle tens of thousands of simultaneous VDoms with no problem.
+- Be concurrent. Components should be able to pause rendering to let the screen paint the next frame.
+- Be disconnected from a specific renderer (no WebSys dependency in the core crate).
+- Support server-side-rendering (SSR). VNodes should render to a string that can be served via a web server.
 - Be "live". Components should be able to be both server rendered and client rendered without needing frontend APIs.
 - Be modular. Components and hooks should be work anywhere without worrying about target platform.

 ## Safety
 
+Dioxus uses unsafe. The design of Dioxus *requires* unsafe (self-referential trees).
+
+All of our test suite passes MIRI without errors.
+
 Dioxus deals with arenas, lifetimes, asynchronous tasks, custom allocators, pinning, and a lot more foundational low-level work that is very difficult to implement with 0 unsafe.
 
 If you don't want to use a crate that uses unsafe, then this crate is not for you.
 
-however, we are always interested in decreasing the scope of the core VirtualDom to make it easier to review.
+However, we are always interested in decreasing the scope of the core VirtualDom to make it easier to review. We'd be happy to welcome PRs that can eliminate unsafe code while still upholding the numerous variants required to execute certain features.

-There's a few invariants that are very important:
-
-- References to `ScopeInner` and `Props` passed into components are *always* valid for as long as the component exists. Even if the scope backing is resized to fit more scopes, the scope has to stay the same place in memory.

-## Suspense
-
-Suspense is done through combinators on values. 
-
-```rust
-let name = get_name(cx).suspend();
-
-rsx!(
-    div {
-        {name}
-        div {
-            div {
-    
-            }
-        }
-    }
-)
