 ## About the Framework
 
 Leptos is a full-stack, isomorphic Rust web framework leveraging fine-grained reactivity to build declarative user interfaces.
@@ -119,7 +113,7 @@ People usually mean one of three things by this question.
 
 1. **Are the APIs stable?** i.e., will I have to rewrite my whole app from Leptos 0.1 to 0.2 to 0.3 to 0.4, or can I write it now and benefit from new features and updates as new versions come?
 
-The APIs are basically settled. We’re adding new features, but we’re very happy with where the type system and patterns have landed. I would not expect major breaking changes to your code to adapt to future releases, in terms of architecture.
+The APIs are basically settled. We’re adding new features, but we’re very happy with where the type system and patterns have landed. I would not expect major breaking changes to your code to adapt to future releases. The sorts of breaking changes that we discuss are things like “Oh yeah, that function should probably take `cx` as its argument...” not major changes to the way you write your application.
 
 2. **Are there bugs?**
 
@@ -158,13 +152,13 @@ There are some practical differences that make a significant difference:
 
 - **Templating:** Leptos uses a JSX-like template format (built on [syn-rsx](https://github.com/stoically/syn-rsx)) for its `view` macro. Sycamore offers the choice of its own templating DSL or a builder syntax.
 - **Server integration:** Leptos provides primitives that encourage HTML streaming and allow for easy async integration and RPC calls, even without WASM enabled, making it easy to opt into integrations between your frontend and backend code without pushing you toward any particular metaframework patterns.
-- **Read-write segregation:** Leptos, like Solid, encourages read-write segregation between signal getters and setters, so you end up accessing signals with tuples like `let (count, set_count) = create_signal(0);` _(If you prefer or if it's more convenient for your API, you can use [`create_rw_signal`](https://docs.rs/leptos/latest/leptos/fn.create_rw_signal.html) to give a unified read/write signal.)_

 - **Signals are functions:** In Leptos, you can call a signal to access it rather than calling a specific method (so, `count()` instead of `count.get()`) This creates a more consistent mental model: accessing a reactive value is always a matter of calling a function. For example:
 
   ```rust
-  let (count, set_count) = create_signal(0); // a signal
+  let (count, set_count) = create_signal(cx, 0); // a signal
   let double_count = move || count() * 2; // a derived signal
-  let memoized_count = create_memo(move |_| count() * 3); // a memo
+  let memoized_count = create_memo(cx, move |_| count() * 3); // a memo
   // all are accessed by calling them
   assert_eq!(count(), 0);
   assert_eq!(double_count(), 0);

-But you can tell rust-analyzer to ignore certain proc macros. For `#[component]` and `#[server]` especially, which annotate function bodies but don't actually transform anything inside the body of your function, this can be really helpful.

-## Conditional Routes
-
-`leptos_router` is based on the assumption that you have one and only one `<Routes/>` component in your app. It uses this to generate routes on the server side, optimize route matching by caching calculated branches, and render your application.
-
-You should not conditionally render `<Routes/>` using another component like `<Show/>` or `<Suspense/>`.
-
-```rust
-// ❌ don't do this!
-view! {
-  <Show when=|| is_loaded() fallback=|| view! { <p>"Loading"</p> }>
-    <Routes>
-      <Route path="/" view=Home/>
-    </Routes>
-  </Show>
-}
-```
-
-Instead, you can use nested routing to render your `<Routes/>` once, and conditionally render the router outlet:
-
-```rust
-// ✅ do this instead!
-view! {
-  <Routes>
-    // parent route
-    <Route path="/" view=move || {
-      view! {
-        // only show the outlet if data have loaded

 - We provide the macro a path. This is a prefix for the path at which we’ll mount a server function handler on our server.

 - You’ll need to have `serde` as a dependency with the `derive` featured enabled for the macro to work properly. You can easily add it to `Cargo.toml` with `cargo add serde --features=derive`.
 
-## Server Function URL Prefixes
-
-You can optionally define a specific URL prefix to be used in the definition of the server function.
-This is done by providing an optional 2nd argument to the `#[server]` macro.
-By default the URL prefix will be `/api`, if not specified.
-Here are some examples:
-
-```rust
-#[server(AddTodo)]         // will use the default URL prefix of `/api`
-#[server(AddTodo, "/foo")] // will use the URL prefix of `/foo`
-```
-
 ## Server Function Encodings
 
 By default, the server function call is a `POST` request that serializes the arguments as URL-encoded form data in the body of the request. (This means that server functions can be called from HTML forms, which we’ll see in a future chapter.) But there are a few other methods supported. Optionally, we can provide another argument to the `#[server]` macro to specify an alternate encoding:
@@ -116,21 +105,6 @@ In other words, you have two choices:
 >
 > The CBOR encoding is suported for historical reasons; an earlier version of server functions used a URL encoding that didn’t support nested objects like structs or vectors as server function arguments, which CBOR did. But note that the CBOR forms encounter the same issue as `PUT`, `DELETE`, or JSON: they do not degrade gracefully if the WASM version of your app is not available.
 
-
-## Server Functions Endpoint Paths
-
-By default, a unique path will be generated. You can optionally define a specific endpoint path to be used in the URL. This is done by providing an optional 4th argument to the `#[server]` macro. Leptos will generate the complete path by concatenating the URL prefix (2nd argument) and the endpoint path (4th argument).
-For example,
-
-```rust
-#[server(MyServerFnType, "/api", "Url", "hello")]
-```
-will generate a server function endpoint at `/api/hello` that accepts a POST request.
-
-> **Can I use the same server function endpoint path with multiple encodings?**
->
-> No. Different server functions must have unique paths. The `#[server]` macro automatically generates unique paths, but you need to be careful if you choose to specify the complete path manually, as the server looks up server functions by their path.
-
 ## An Important Note on Security
 
 Server functions are a cool technology, but it’s very important to remember. **Server functions are not magic; they’re syntax sugar for defining a public API.** The _body_ of a server function is never made public; it’s just part of your server binary. But the server function is a publicly accessible API endpoint, and it’s return value is just a JSON or similar blob. You should _never_ return something sensitive from a server function.

+The problem here is that `create_effect` runs **immediately** and **synchronously**, but only in the browser. As a result, on the server, `loaded` is false, and a `<div>` is rendered.

-# No Macros: The View Builder Syntax
-
-> If you’re perfectly happy with the `view!` macro syntax described so far, you’re welcome to skip this chapter. The builder syntax described in this section is always available, but never required.
-
-For one reason or another, many developers would prefer to avoid macros. Perhaps you don’t like the limited `rustfmt` support. (Although, you should check out [`leptosfmt`](https://github.com/bram209/leptosfmt), which is an excellent tool!) Perhaps you worry about the effect of macros on compile time. Perhaps you prefer the aesthetics of pure Rust syntax, or you have trouble context-switching between an HTML-like syntax and your Rust code. Or perhaps you want more flexibility in how you create and manipulate HTML elements than the `view` macro provides.
-
-If you fall into any of those camps, the builder syntax may be for you.
-
-The `view` macro expands an HTML-like syntax to a series of Rust functions and method calls. If you’d rather not use the `view` macro, you can simply use that expanded syntax yourself. And it’s actually pretty nice!
-
-First off, if you want you can even drop the `#[component]` macro: a component is just a setup function that creates your view, so you can define a component as a simple function call:
-
-```rust
-pub fn counter(initial_value: i32, step: u32) -> impl IntoView { }
-```
-
-Elements are created by calling a function with the same name as the HTML element:
-
-```rust
-p()
-```
-
-You can add children to the element with [`.child()`](https://docs.rs/leptos/latest/leptos/struct.HtmlElement.html#method.child), which takes a single child or a tuple or array of types that implement [`IntoView`](https://docs.rs/leptos/latest/leptos/trait.IntoView.html).
-
-```rust
-p().child((em().child("Big, "), strong().child("bold "), "text"))
-```
-
-Attributes are added with [`.attr()`](https://docs.rs/leptos/latest/leptos/struct.HtmlElement.html#method.attr). This can take any of the same types that you could pass as an attribute into the view macro (types that implement [`IntoAttribute`](https://docs.rs/leptos/latest/leptos/trait.IntoAttribute.html)).
-
-```rust
-p().attr("id", "foo").attr("data-count", move || count().to_string())
-```
-
-Similarly, the `class:`, `prop:`, and `style:` syntaxes map directly onto [`.class()`](https://docs.rs/leptos/latest/leptos/struct.HtmlElement.html#method.class), [`.prop()`](https://docs.rs/leptos/latest/leptos/struct.HtmlElement.html#method.prop), and [`.style()`](https://docs.rs/leptos/latest/leptos/struct.HtmlElement.html#method.style) methods.
-
-Event listeners can be added with [`.on()`](https://docs.rs/leptos/latest/leptos/struct.HtmlElement.html#method.on). Typed events found in [`leptos::ev`](https://docs.rs/leptos/latest/leptos/ev/index.html) prevent typos in event names and allow for correct type inference in the callback function.
-
-```rust
-button()
-    .on(ev::click, move |_| set_count.update(|count| count.clear()))
-    .child("Clear")
-```
-
-> Many additional methods can be found in the [`HtmlElement`](https://docs.rs/leptos/latest/leptos/struct.HtmlElement.html#method.child) docs, including some methods that are not directly available in the `view` macro.
-
-All of this adds up to a very Rusty syntax to build full-featured views, if you prefer this style.
-
-```rust
-/// A simple counter view.
-// A component is really just a function call: it runs once to create the DOM and reactive system
-pub fn counter(initial_value: i32, step: u32) -> impl IntoView {
-    let (count, set_count) = create_signal(0);
-
-    div()
-        .child((
-            button()
-                // typed events found in leptos::ev
-                // 1) prevent typos in event names
-                // 2) allow for correct type inference in callbacks
-                .on(ev::click, move |_| set_count.update(|count| count.clear()))
-                .child("Clear"),
-            button()
-                .on(ev::click, move |_| {
-                    set_count.update(|count| count.decrease())
-                })
-                .child("-1"),
-            span().child(("Value: ", move || count.get().value(), "!")),
-            button()
-                .on(ev::click, move |_| {
-                    set_count.update(|count| count.increase())
-                })
-                .child("+1"),
-        ))
-}
-```
-
-This also has the benefit of being more flexible: because these are all plain Rust functions and methods, it’s easier to use them in things like iterator adapters without any additional “magic”:
-
-```rust
-// take some set of attribute names and values
-let attrs: Vec<(&str, AttributeValue)> = todo!();
-// you can use the builder syntax to “spread” these onto the
-// element in a way that’s not possible with the view macro
-let p = attrs
-    .into_iter()
-    .fold(p(), |el, (name, value)| el.attr(name, value));
-
-```
-
-> ## Performance Note
->
-> One caveat: the `view` macro applies significant optimizations in server-side-rendering (SSR) mode to improve HTML rendering performance significantly (think 2-4x faster, depending on the characteristics of any given app). It does this by analyzing your `view` at compile time and converting the static parts into simple HTML strings, rather than expanding them into the builder syntax.
->
-> This means two things:
->
-> 1. The builder syntax and `view` macro should not be mixed, or should only be mixed very carefully: at least in SSR mode, the output of the `view` should be treated as a “black box” that can’t have additional builder methods applied to it without causing inconsistencies.
-> 2. Using the builder syntax will result in less-than-optimal SSR performance. It won’t be slow, by any means (and it’s worth running your own benchmarks in any case), just slower than the `view`-optimized version.

-## Cargo Make
-
-[Cargo Make](https://sagiegurari.github.io/cargo-make/) is used to build, test, and run examples.
-
-Here are the highlights.
-
-- Extendable custom task files are located in the [cargo-make](./cargo-make/) directory
-- Running a task will automatically install `cargo` dependencies 
-- Each `Makefile.toml` file must extend the [cargo-make/main.toml](./cargo-make/main.toml) file
-- [cargo-make](./cargo-make/) files that end in `*-test.toml` configure web testing strategies
-- Run `cargo make test-report` to learn which examples have web tests
-
-## Getting Started
-
-Follow these steps to get any example up and running.
-
-1. `cd` to the example root directory
-2. Run `cargo make ci` to setup and test the example
-3. Run `cargo make start` to run the example
-4. Open the client URL in the console output (<http://127.0.0.1:8080> or <http://127.0.0.1:3000> by default)
-
-## Prerequisites
-
-Example projects depend on the following tools. Please install them as needed.
-
-- [Rust](https://www.rust-lang.org/)
-- Nightly Rust
-  - Run `rustup toolchain install nightly`
-  - Run `rustup target add wasm32-unknown-unknown`
-- [Cargo Make](https://sagiegurari.github.io/cargo-make/)
-  - Run `cargo install --force cargo-make`
-  - Setup a command alias like `alias cm='cargo make'` to reduce typing (**_Optional_**)
-- [Node Version Manager](https://github.com/nvm-sh/nvm/) (**_Optional_**)
-- [Node.js](https://nodejs.org/)
-- [pnpm](https://pnpm.io/) (**_Optional_**)

-# Server Side Rendering
-
-## Cargo Leptos
-
-cargo-leptos is now the easiest and most featureful way to build server side rendered apps with hydration. It provides automatic recompilation of client and server code, wasm optimisation, CSS minification, and more! Check out more about it [here](https://github.com/akesson/cargo-leptos)
-
-1. Install cargo-leptos
-
-```bash
-cargo install --locked cargo-leptos
-```
-
-2. Build the site in watch mode, recompiling on file changes
-
-```bash
-cargo leptos watch
-```
-
-Open browser on [http://localhost:3000/](http://localhost:3000/)
-
-3. When ready to deploy, run
-
-```bash
-cargo leptos build --release
-```
-
-## WASM Pack
-
-To run it as a server side app with hydration, you'll need to have wasm-pack installed.
-
-0. Edit the `[package.metadata.leptos]` section and set `site-root` to `"."`. For examples with CSS you also want to change the path of the `<StyleSheet / >` component in the root component to point towards the CSS file in the root. This tells leptos that the WASM/JS files generated by wasm-pack are available at `./pkg` and that the CSS files are no longer processed by cargo-leptos. Building to alternative folders is not supported at this time. You'll also want to edit the call to `get_configuration()` to pass in `Some(Cargo.toml)`, so that Leptos will read the settings instead of cargo-leptos. If you do so, your file/folder names cannot include dashes.
-
-1. Install wasm-pack
-
-```bash
-cargo install wasm-pack
-```
-
-2. Build the Webassembly used to hydrate the HTML from the server
-
-```bash
-wasm-pack build --target=web --debug --no-default-features --features=hydrate
-```
-
-3. Run the server to serve the Webassembly, JS, and HTML
-
-```bash
-cargo run --no-default-features --features=ssr
-```
-
-### Server Side Rendering With Hydration
-
-To run it as a server side app with hydration, first you should run
-
-```bash
-wasm-pack build --target=web --debug --no-default-features --features=hydrate
-```
-
-to generate the WebAssembly to hydrate the HTML delivered from the server.
-
-Then run the server with `cargo run` to serve the server side rendered HTML and the WASM bundle for hydration.
-
-```bash
-cargo run --no-default-features --features=ssr
-```
-
-> Note that if your hydration code changes, you will have to rerun the wasm-pack command above before running
-> `cargo run`

Unlike the other counters example, it will compile on Rust stable, because it has the `stable` feature enabled.
