+# Summary
+
+Better conventions for Server/Client Components, as an revision to [the v2](https://github.com/reactjs/rfcs/pull/227) of [the original proposal v1](https://github.com/reactjs/rfcs/pull/189)
+
+<sup>Note: The v1 and v2 terms used throughout this RFC refer to the above hyperlinked RFCs only.</sup>
+
+# Changes Since v2
+
+- using `"use csr"` instead of `"use client"` i.e. replacing `client` with `csr`
+- similarly, reserve `"use ssr"` for future use with Server only.
+
+# Basic example
+
+<!-- If the proposal involves a new or changed API, include a basic code example.
+Omit this section if it's not applicable. -->
+
+To mark a component as a Client Component, add `'use csr'` directive at the top of your file. This lets you use features like state and event handlers:
+
+```js
+'use csr';
+
+import { useState } from 'react';
+
+function Button({ children, onClick }) {
+  // ...
+}
+```
+
+Diff - current syntax and conventions:
+```diff
++'use csr';
+-'use client';
+
+import { useState } from 'react';
+
+function Button({ children, onClick }) {
+  // ...
+}
+```
+
+## `"use csr"` Directive
+
+```js
+// Parent.js
+import Component from "./Component.js";
+function Parent() {
+  // Component is of type Reference<T> where T is the type
+  // of the default export of Component.js
+  // Because of this React knows that it can't render it on
+  // the server and instead will leave it as a placeholder
+  // to later be rendered on the client.
+  return <Component />;
+}
+```
+
+```js
+// Component.js
+"use csr";
+
+function Component() {
+  let [state, setState] = useState(false);
+  return <OtherClientComponent onClick={() => setState(true)} value={state} />;
+}
+```
+
+# Motivation
+
+<!-- Why are we doing this? What use cases does it support? What is the expected
+outcome?
+
+Please focus on explaining the motivation so that if this RFC is not accepted,
+the motivation could be used to develop alternative solutions. In other words,
+enumerate the constraints you are trying to solve without coupling them too
+closely to the solution you have in mind. -->
+
+
+
+# Detailed design
+
+<!-- This is the bulk of the RFC. Explain the design in enough detail for somebody
+familiar with React to understand, and for somebody familiar with the
+implementation to implement. This should get into specifics and corner-cases,
+and include examples of how the feature is used. Any new terminology should be
+defined here. -->
+
+
+
+# Drawbacks
+
+<!-- 
+Why should we *not* do this? Please consider:
+
+- implementation cost, both in term of code size and complexity
+- whether the proposed feature can be implemented in user space
+- the impact on teaching people React
+- integration of this feature with other existing and planned features
+- cost of migrating existing React applications (is it a breaking change?)
+
+There are tradeoffs to choosing any path. Attempt to identify them here. -->
+
+
+
+# Alternatives
+
+<!-- What other designs have been considered? What is the impact of not doing this? -->
+
+
+
+# Adoption strategy
+<!-- 
+If we implement this proposal, how will existing React developers adopt it? Is
+this a breaking change? Can we write a codemod? Should we coordinate with
+other projects or libraries? -->
+
+# How we teach this
+
+<!-- What names and terminology work best for these concepts and why? How is this
+idea best presented? As a continuation of existing React patterns?
+
+Would the acceptance of this proposal mean the React documentation must be
+re-organized or altered? Does it change how React is taught to new developers
+at any level?
+
+How should this feature be taught to existing React developers? -->
+
+
+# Unresolved questions
+
+<!-- Optional, but suggested for first drafts. What parts of the design are still
+TBD? -->
