+# Leptos Counters Example on Rust Stable
+
+This example showcases a basic Leptos app with many counters. It is a good example of how to setup a basic reactive app with signals and effects, and how to interact with browser events. Unlike the other counters example, it will compile on Rust stable, because it has the `stable` feature enabled.
+
+## 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.

+Unlike the other examples, this has a variety of build prerequisites that are out of scope of this crate.

+# 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
+
+> If you don't have `trunk` installed, [click here for install instructions.](https://trunkrs.dev/)

-# Leptos Starter Template
-
-This is a template demonstrating how to integrate [TailwindCSS](https://tailwindcss.com/) with the [Leptos](https://github.com/gbj/leptos) web framework and the [cargo-leptos](https://github.com/akesson/cargo-leptos) tool.
-
-If you don't have `cargo-leptos` installed you can install it with
-
-`cargo install --locked cargo-leptos`
-
-Then run
-
-`npx tailwindcss -i ./input.css -o ./style/output.css --watch`
-
-and
-
-`cargo leptos watch`
-
-in this directory.
-
-You can begin editing your app at `src/app/mod.rs`.
-
-## Installing Tailwind
-
-You can install Tailwind using `npm`:
-
-```bash
-npm install -D tailwindcss
-```
-
-If you'd rather not use `npm`, you can install the Tailwind binary [here](https://github.com/tailwindlabs/tailwindcss/releases).
-
-## Setting up with VS Code and Additional Tools
-
-If you're using VS Code, add the following to your `settings.json`
-
-```json
-  "emmet.includeLanguages": {
-    "rust": "html",
-    "*.rs": "html"
-  },
-  "tailwindCSS.includeLanguages": {
-      "rust": "html",
-      "*.rs": "html"
-  },
-  "files.associations": {
-      "*.rs": "rust"
-  },
-  "editor.quickSuggestions": {
-    "other": "on",
-    "comments": "on",
-    "strings": true
-  },
-  "css.validate": false,
-```
-
-
-Install [Tailwind CSS Intellisense](https://marketplace.visualstudio.com/items?itemName=bradlc.vscode-tailwindcss).
-
-    Install "VS Browser" extension, a browser at the right window.
-    Allow vscode Ports forward: 3000, 3001.
-
-
-## Notes about Tooling
-
-By default, `cargo-leptos` uses `nightly` Rust, `cargo-generate`, and `sass`. If you run into any trouble, you may need to install one or more of these tools.
-
-1. `rustup toolchain install nightly --allow-downgrade` - make sure you have Rust nightly
-2. `rustup default nightly` - setup nightly as default, or you can use rust-toolchain file later on
-3. `rustup target add wasm32-unknown-unknown` - add the ability to compile Rust to WebAssembly
-4. `cargo install cargo-generate` - install `cargo-generate` binary (should be installed automatically in future)
-5. `npm install -g sass` - install `dart-sass` (should be optional in future
-

+# Leptos Todo App Sqlite with CBOR
+
+This example creates a basic todo app with an Actix backend that uses Leptos' server functions to call sqlx from the client and seamlessly run it on the server. It is identical to the todo-app-sqlite example, but utilizes CBOR encoding for one of the server functions
+
+## 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 --no-default-features --features=hydrate
+```
+
+to generate the WebAssembly to hydrate the HTML that is generated on 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
+> This should be temporary, and vastly improve once cargo-leptos becomes ready for prime time!
