+
+The `@react.componentWithProps` decorator is used to annotate functions that are [React](/docs/react/latest/elements-and-jsx) components which take in a record type as prop.
+This decorator will ensure your component gets an uppercased name.
+
+
+> **Note**
+> The `@react.componentWithProps` decorator requires the [react-jsx or jsx config](/docs/react/latest/installation) to be set in your `rescript.json` to enable the required React transformations.

 We've created a `Greeting.res` file that contains a `make` function that doesn't receive any props (the function doesn't receive any parameters), and returns a `React.element` that represents `<div> Hello ReScripters! </div>` in the rendered DOM.

 ## Defining Props

 **The best use-case for `children` is to pass down `React.element`s without any semantic order or implementation details!**
 
 
+## @react decorators
+
+You might've wondered what `@react.component` actually does.
+It's a decorator that tells the ReScript compiler to treat the function as a React component, transforming it at the syntax level.
+
+In JavaScript, a React component is just a function that takes props (an object) and returns JSX. In ReScript, props are typically represented as a record type.
+The `@react.component` decorator automatically generates that record type and wraps the function for you—so you don't have to.
+
+```res
+// Counter.res
+
+@react.component
+let make = (~title, ~count) => {
+  <h1> {React.string(title)} {React.int(count)} </h1>
+}
+
+// This is equivalent to writing:
+
+type props = {title: string, count: int}
+
+let \"Counter" = ({title, count}: props) => {
+  <h1> {React.string(title)} {React.int(count)} </h1>
+}
+```
+
+However, writing it manually like this means you lose the `make` function name, which prevents JSX from working as expected when using the component elsewhere.
+
+Having an uppercased function name also helps distinguish React components from regular functions in [React DevTools](https://react.dev/learn/react-developer-tools).
+
+If you prefer defining your own props record, you can use `@react.componentWithProps`. This gives you full control over the props type while still generating a proper uppercased component.

+    {React.int(props.count)}

+}
+```

+```js
+import * as JsxRuntime from "react/jsx-runtime";
+
+function Counter(props) {
+  return JsxRuntime.jsxs("h1", {
+    children: [
+      props.title,
+      props.count
+    ]
+  });
+}

 ## Props & Type Inference
 
 The ReScript type system is really good at inferring the prop types just by looking at its prop usage.

 ## Component Naming
 
-Because components are actually a pair of functions, they have to belong to a module to be used in JSX. It makes sense to use these modules for identification purposes as well. `@react.component` automatically adds the name for you based on the module you are in.
