+# Contributor Covenant Code of Conduct
+
+_This Code of Conduct is based on the [Rust Code of Conduct](https://www.rust-lang.org/policies/code-of-conduct)
+and the [Bevy Code of Conduct](https://raw.githubusercontent.com/bevyengine/bevy/main/CODE_OF_CONDUCT.md),
+which are adapted from the [Node.js Policy on Trolling](http://blog.izs.me/post/30036893703/policy-on-trolling) 
+and the [Contributor Covenant](https://www.contributor-covenant.org)._
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+We are a community of people learning and exploring how to build better web applications
+with Rust. When interacting with one another, please remember that there are no experts and there are
+no stupid questions. Assume the best in other people's communication, and take a step back if
+you find yourself getting defensive.
+
+Please note the following guidelines as well:
+
+* Please avoid using overtly sexual aliases or other nicknames that might detract from a friendly, safe and welcoming environment for all.
+* Please be kind and courteous. There’s no need to be mean or rude.
+* Respect that people have differences of opinion and that every design or implementation choice carries a trade-off and numerous costs. There is seldom a right answer.
+* Please keep unstructured critique to a minimum. If you have solid ideas you want to experiment with, make a fork and see how it works.
+* We will exclude you from interaction if you insult, demean or harass anyone. That is not welcome behavior. We interpret the term “harassment” as including the definition in the [Citizen Code of Conduct](https://github.com/stumpsyn/policies/blob/master/citizen_code_of_conduct.md); if you have any lack of clarity about what might be included in that concept, please read their definition. In particular, we don’t tolerate behavior that excludes people in socially marginalized groups.
+* Private harassment is also unacceptable. No matter who you are, if you feel you have been or are being harassed or made uncomfortable by a community member, please contact the maintainers immediately. Whether you’re a regular contributor or a newcomer, we care about making this community a safe place for you and we’ve got your back.
+* Do not make casual mention of slavery or indentured servitude and/or false comparisons of one's occupation or situation to slavery. Please consider using or asking about alternate terminology when referring to such metaphors in technology.
+* Likewise any spamming, trolling, flaming, baiting or other attention-stealing behavior is not welcome.
+
+## Moderation
+
+These are the policies for upholding [our community’s standards of conduct](#our-standards). If you feel that a thread needs moderation, please contact the maintainers.
+
+1. Remarks that violate the community standards of conduct, including hateful, hurtful, oppressive, or exclusionary remarks, are not allowed. (Cursing is allowed, but never targeting another user, and never in a hateful manner).
+2. Remarks that maintainers find inappropriate, whether listed in the code of conduct or not, are also not allowed.
+3. Maintainers will first respond to such remarks with a warning.
+4. If the warning is unheeded, the user will be “kicked,” i.e., kicked out of the communication channel to cool off.
+5. If the user comes back and continues to make trouble, they will be banned, i.e., indefinitely excluded.
+6. Maintainers may choose at their discretion to un-ban the user if it was a first offense and they offer the offended party a genuine apology.
+7. If a maintainer bans someone and you think it was unjustified, please take it up with that maintainer, or with a different maintainer, in private. Complaints about bans in-channel are not allowed.
+8. Maintainers are held to a higher standard than other community members. If a maintainer creates an inappropriate situation, they should expect less leeway than others.
+
+The enforcement policies in the code of conduct apply to all official venues, including Discord channels, GitHub repositories, and all other forums.

 ## FAQs
 
+### Is it production ready?
+
+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?
+
+With 0.1 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, for example, a 0.2.0 release.
+
+2. **Are there bugs?**
+
+Yes, I’m sure there are. You can see from the state of our issue tracker over time that there aren’t that _many_ bugs and they’re usually resolved pretty quickly. But for sure, there may be moments where you encounter something that requires a fix at the framework level, which may not be immediately resolved.
+
+3. **Am I a consumer or a contributor?**
+
+This may be the big one: “production ready” implies a certain orientation to a library: that you can basically use it, without any special knowledge of its internals or ability to contribute. Everyone has this at some level in their stack: for example I (@gbj) don’t have the capacity or knowledge to contribute to something like `wasm-bindgen` at this point: I simply rely on it to work.
+
+There are several people in this community using Leptos right now for internal apps at work, who have also become significant contributors. I think this is the right level of production use for now. There may be missing features that you need, and you may end up building them! But for internal apps, if you’re willing to build and contribute missing pieces along the way, the framework is definitely usable right now.
+
 ### Can I use this for native GUI?
 
 Sure! Obviously the `view` macro is for generating DOM nodes but you can use the reactive system to drive native any GUI toolkit that uses the same kind of object-oriented, event-callback-based framework as the DOM pretty easily. The principles are the same:

 ### How is this different from Yew/Dioxus?
 
@@ -124,7 +144,6 @@ There are some practical differences that make a significant difference:
 
 - **Maturity:** Sycamore is obviously a much more mature and stable library with a larger ecosystem.
 - **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.
-- **Template node cloning:** Leptos's `view` macro compiles to a static HTML string and a set of instructions of how to assign its reactive values. This means that at runtime, Leptos can clone a `<template>` node rather than calling `document.createElement()` to create DOM nodes. This is a _significantly_ faster way of rendering components.
 - **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(cx, 0);` _(If you prefer or if it's more convenient for your API, you can use `create_rw_signal` 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:

+This book is intended as an introduction to the [Leptos](https://github.com/leptos-rs/leptos) Web framework. Together, we’ll build a simple todo app—first as a client-side app, then as a full-stack app.
 
 The guide doesn’t assume you know anything about fine-grained reactivity or the details of modern Web frameworks. It does assume you are familiar with the Rust programming language, HTML, CSS, and the DOM and other Web APIs.

 ## Client Side Rendering
-To run it as a Client Side App, you can issue  `trunk serve --open` in the root. This will build the entire
-app into one CSR bundle. Make sure you have trunk installed with `cargo install trunk`.

+This means it is not possible to produce a working CSR-only version as a non-static server is required.

+# Parent Child Example
+
+This example highlights four different ways that child components can communicate with their parent:
+
+1. <ButtonA/>: passing a WriteSignal as one of the child component props,
+   for the child component to write into and the parent to read
+2. <ButtonB/>: passing a closure as one of the child component props, for
+   the child component to call
+3. <ButtonC/>: adding a simple event listener on the child component itself
+4. <ButtonD/>: providing a context that is used in the component (rather than prop drilling)
+
+## Client Side Rendering
+
+To run it as a Client Side App, you can issue `trunk serve --open` in the root. This will build the entire
+app into one CSR bundle
