15.5.2

* Update example snippet in old 'React.addons' doc page

This makes the example more consistent.

* Add back the pointers in docs that were mistakenly removed

In https://github.com/facebook/react/pull/9359 we accidentally removed
pointers in some doc pages. Putting them back now.

* Link to npm package instead of github page

This seems like a more stable place to link to in the 'context'
document.
Based on @bvaughn's feedback in https://github.com/facebook/react/pull/9359

([@gaearon](https://github.com/gaearon) in [#13302](https://github.com/facebook/react/pull/13302))
-
-## 16.0.0 (September 26, 2017)
-
-### New JS Environment Requirements
-
- * React 16 depends on the collection types [Map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map) and [Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set), as well as [requestAnimationFrame](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame). If you support older browsers and devices which may not yet provide these natively (e.g. <IE11), [you may want to include a polyfill](https://gist.github.com/gaearon/9a4d54653ae9c50af6c54b4e0e56b583).
-
-### New Features
-* Components can now return arrays and strings from `render`. (Docs coming soon!)
-* Improved error handling with introduction of "error boundaries". [Error boundaries](https://reactjs.org/blog/2017/07/26/error-handling-in-react-16.html) are React components that catch JavaScript errors anywhere in their child component tree, log those errors, and display a fallback UI instead of the component tree that crashed.
-* First-class support for declaratively rendering a subtree into another DOM node with `ReactDOM.createPortal()`. (Docs coming soon!)
-* Streaming mode for server side rendering is enabled with `ReactDOMServer.renderToNodeStream()` and `ReactDOMServer.renderToStaticNodeStream()`. ([@aickin](https://github.com/aickin) in [#10425](https://github.com/facebook/react/pull/10425), [#10044](https://github.com/facebook/react/pull/10044), [#10039](https://github.com/facebook/react/pull/10039), [#10024](https://github.com/facebook/react/pull/10024), [#9264](https://github.com/facebook/react/pull/9264), and others.)
-* [React DOM now allows passing non-standard attributes](https://reactjs.org/blog/2017/09/08/dom-attributes-in-react-16.html). ([@nhunzaker](https://github.com/nhunzaker) in [#10385](https://github.com/facebook/react/pull/10385), [10564](https://github.com/facebook/react/pull/10564), [#10495](https://github.com/facebook/react/pull/10495) and others)
-
-### Breaking Changes
-- There are several changes to the behavior of scheduling and lifecycle methods:
-  * `ReactDOM.render()` and `ReactDOM.unstable_renderIntoContainer()` now return `null` if called from inside a lifecycle method.
-    * To work around this, you can either use [the new portal API](https://github.com/facebook/react/issues/10309#issuecomment-318433235) or [refs](https://github.com/facebook/react/issues/10309#issuecomment-318434635).
-  * Minor changes to `setState` behavior:
-    * Calling `setState` with null no longer triggers an update. This allows you to decide in an updater function if you want to re-render.
-    * Calling `setState` directly in render always causes an update. This was not previously the case. Regardless, you should not be calling `setState` from render.
-    * `setState` callback (second argument) now fires immediately after `componentDidMount` / `componentDidUpdate` instead of after all components have rendered.
-  * When replacing `<A />` with `<B />`,  `B.componentWillMount` now always happens before  `A.componentWillUnmount`. Previously, `A.componentWillUnmount` could fire first in some cases.
-  * Previously, changing the `ref` to a component would always detach the ref before that component's render is called. Now, we change the `ref` later, when applying the changes to the DOM.
-  * It is not safe to re-render into a container that was modified by something other than React. This worked previously in some cases but was never supported. We now emit a warning in this case. Instead you should clean up your component trees using `ReactDOM.unmountComponentAtNode`. [See this example.](https://github.com/facebook/react/issues/10294#issuecomment-318820987)
-  * `componentDidUpdate` lifecycle no longer receives `prevContext` param. ([@bvaughn](https://github.com/bvaughn) in [#8631](https://github.com/facebook/react/pull/8631))
-  * Non-unique keys may now cause children to be duplicated and/or omitted. Using non-unique keys is not (and has never been) supported, but previously it was a hard error.
-  * Shallow renderer no longer calls `componentDidUpdate()` because DOM refs are not available. This also makes it consistent with `componentDidMount()` (which does not get called in previous versions either).
-  * Shallow renderer does not implement `unstable_batchedUpdates()` anymore.
-  * `ReactDOM.unstable_batchedUpdates` now only takes one extra argument after the callback.
-- The names and paths to the single-file browser builds have changed to emphasize the difference between development and production builds. For example:
-  - `react/dist/react.js` → `react/umd/react.development.js`
-  - `react/dist/react.min.js` → `react/umd/react.production.min.js`
-  - `react-dom/dist/react-dom.js` → `react-dom/umd/react-dom.development.js`
-  - `react-dom/dist/react-dom.min.js` → `react-dom/umd/react-dom.production.min.js`
-* The server renderer has been completely rewritten, with some improvements:
-  * Server rendering does not use markup validation anymore, and instead tries its best to attach to existing DOM, warning about inconsistencies. It also doesn't use comments for empty components and data-reactid attributes on each node anymore.
-  * Hydrating a server rendered container now has an explicit API. Use `ReactDOM.hydrate` instead of `ReactDOM.render` if you're reviving server rendered HTML. Keep using `ReactDOM.render` if you're just doing client-side rendering.
-* When "unknown" props are passed to DOM components, for valid values, React will now render them in the DOM. [See this post for more details.](https://reactjs.org/blog/2017/09/08/dom-attributes-in-react-16.html) ([@nhunzaker](https://github.com/nhunzaker) in [#10385](https://github.com/facebook/react/pull/10385), [10564](https://github.com/facebook/react/pull/10564), [#10495](https://github.com/facebook/react/pull/10495) and others)
-* Errors in the render and lifecycle methods now unmount the component tree by default. To prevent this, add [error boundaries](https://reactjs.org/blog/2017/07/26/error-handling-in-react-16.html) to the appropriate places in the UI.
-
-### Removed Deprecations
-
-- There is no `react-with-addons.js` build anymore. All compatible addons are published separately on npm, and have single-file browser versions if you need them.
-- The deprecations introduced in 15.x have been removed from the core package. `React.createClass` is now available as create-react-class, `React.PropTypes` as prop-types, `React.DOM` as react-dom-factories, react-addons-test-utils as react-dom/test-utils, and shallow renderer as react-test-renderer/shallow. See [15.5.0](https://reactjs.org/blog/2017/04/07/react-v15.5.0.html) and [15.6.0](https://reactjs.org/blog/2017/06/13/react-v15.6.0.html) blog posts for instructions on migrating code and automated codemods.

 ## 15.0.0 (April 7, 2016)
 
 ### Major changes
 
-- **Initial render now uses `document.createElement` instead of generating HTML.** Previously we would generate a large string of HTML and then set `node.innerHTML`. At the time, this was decided to be faster than using `document.createElement` for the majority of cases and browsers that we supported. Browsers have continued to improve and so overwhelmingly this is no longer true. By using `createElement` we can make other parts of React faster. ([@sophiebits](https://github.com/sophiebits) in [#5205](https://github.com/facebook/react/pull/5205))
-- **`data-reactid` is no longer on every node.** As a result of using `document.createElement`, we can prime the node cache as we create DOM nodes, allowing us to skip a potential lookup (which used the `data-reactid` attribute). Root nodes will have a `data-reactroot` attribute and server generated markup will still contain `data-reactid`. ([@sophiebits](https://github.com/sophiebits) in [#5205](https://github.com/facebook/react/pull/5205))

([@spicyj](https://github.com/spicyj) in [#5205](https://github.com/facebook/react/pull/5205))
 - **No more extra `<span>`s.** ReactDOM will now render plain text nodes interspersed with comment nodes that are used for demarcation. This gives us the same ability to update individual pieces of text, without creating extra nested nodes. If you were targeting these `<span>`s in your CSS, you will need to adjust accordingly. You can always render them explicitly in your components. ([@mwiencek](https://github.com/mwiencek) in [#5753](https://github.com/facebook/react/pull/5753))
-- **Rendering `null` now uses comment nodes.** Previously `null` would render to `<noscript>` elements. We now use comment nodes. This may cause issues if making use of `:nth-child` CSS selectors. While we consider this rendering behavior an implementation detail of React, it's worth noting the potential problem.

([@spicyj](https://github.com/spicyj) in [#5451](https://github.com/facebook/react/pull/5451))
 - **Functional components can now return `null`.** We added support for [defining stateless components as functions](/react/blog/2015/09/10/react-v0.14-rc1.html#stateless-function-components) in React 0.14. However, React 0.14 still allowed you to define a class component without extending `React.Component` or using `React.createClass()`, so [we couldn’t reliably tell if your component is a function or a class](https://github.com/facebook/react/issues/5355), and did not allow returning `null` from it. This issue is solved in React 15, and you can now return `null` from any component, whether it is a class or a function. ([@jimfb](https://github.com/jimfb) in [#5884](https://github.com/facebook/react/pull/5884))
 - **Improved SVG support.** All SVG tags are now fully supported. (Uncommon SVG tags are not present on the `React.DOM` element helper, but JSX and `React.createElement` work on all tag names.) All SVG attributes that are implemented by the browsers should be supported too. If you find any attributes that we have missed, please [let us know in this issue](https://github.com/facebook/react/issues/1657).

 - Split the main `react` package into two: `react` and `react-dom`.  This paves the way to writing components that can be shared between the web version of React and React Native.  This means you will need to include both files and some functions have been moved from `React` to `ReactDOM`.
 - Addons have been moved to separate packages (`react-addons-clone-with-props`, `react-addons-create-fragment`, `react-addons-css-transition-group`, `react-addons-linked-state-mixin`, `react-addons-perf`, `react-addons-pure-render-mixin`, `react-addons-shallow-compare`, `react-addons-test-utils`, `react-addons-transition-group`, `react-addons-update`, `ReactDOM.unstable_batchedUpdates`).
-- Stateless functional components - React components were previously created using React.createClass or using ES6 classes.  This release adds a [new syntax](https://reactjs.org/docs/reusable-components.html#stateless-functions) where a user defines a single [stateless render function](https://reactjs.org/docs/reusable-components.html#stateless-functions) (with one parameter: `props`) which returns a JSX element, and this function may be used as a component.

 - Refs to DOM components as the DOM node itself. Previously the only useful thing you can do with a DOM component is call `getDOMNode()` to get the underlying DOM node. Starting with this release, a ref to a DOM component _is_ the actual DOM node. **Note that refs to custom (user-defined) components work exactly as before; only the built-in DOM components are affected by this change.**

 - Add-Ons: Due to the DOM node refs change mentioned above, `TestUtils.findAllInRenderedTree` and related helpers are no longer able to take a DOM component, only a custom component.
-- The `props` object is now frozen, so mutating props after creating a component element is no longer supported. In most cases, [`React.cloneElement`](https://reactjs.org/docs/react-api.html#cloneelement) should be used instead.

 - `setProps` and `replaceProps` are now deprecated. Instead, call ReactDOM.render again at the top level with the new props.
-- ES6 component classes must now extend `React.Component` in order to enable stateless function components. The [ES3 module pattern](https://reactjs.org/blog/2015/01/27/react-v0.13.0-beta-1.html#other-languages) will continue to work.

-- Add-Ons: `cloneWithProps` is now deprecated. Use [`React.cloneElement`](https://reactjs.org/docs/react-api.html#cloneelement) instead (unlike `cloneWithProps`, `cloneElement` does not merge `className` or `style` automatically; you can merge them manually if needed).

 - Add-Ons: To improve reliability, `CSSTransitionGroup` will no longer listen to transition events. Instead, you should specify transition durations manually using props such as `transitionEnterTimeout={500}`.
 
 ### Notable enhancements
 
 - Added `React.Children.toArray` which takes a nested children object and returns a flat array with keys assigned to each child. This helper makes it easier to manipulate collections of children in your `render` methods, especially if you want to reorder or slice `this.props.children` before passing it down. In addition, `React.Children.map` now returns plain arrays too.
 - React uses `console.error` instead of `console.warn` for warnings so that browsers show a full stack trace in the console. (Our warnings appear when you use patterns that will break in future releases and for code that is likely to behave unexpectedly, so we do consider our warnings to be “must-fix” errors.)
-- Previously, including untrusted objects as React children [could result in an XSS security vulnerability](http://danlec.com/blog/xss-via-a-spoofed-react-element). This problem should be avoided by properly validating input at the application layer and by never passing untrusted objects around your application code. As an additional layer of protection, [React now tags elements](https://github.com/facebook/react/pull/4832) with a specific [ES2015 (ES6) `Symbol`](http://www.2ality.com/2014/12/es6-symbols.html) in browsers that support it, in order to ensure that React never considers untrusted JSON to be a valid element. If this extra security protection is important to you, you should add a `Symbol` polyfill for older browsers, such as the one included by [Babel’s polyfill](https://babeljs.io/docs/usage/polyfill/).

 - React DOM now supports these standard HTML attributes: `capture`, `challenge`, `inputMode`, `is`, `keyParams`, `keyType`, `minLength`, `summary`, `wrap`. It also now supports these non-standard attributes: `autoSave`, `results`, `security`.
 - React DOM now supports these SVG attributes, which render into namespaced attributes: `xlinkActuate`, `xlinkArcrole`, `xlinkHref`, `xlinkRole`, `xlinkShow`, `xlinkTitle`, `xlinkType`, `xmlBase`, `xmlLang`, `xmlSpace`.

-* Added a new top-level API `React.cloneElement(el, props)` for making copies of React elements – see the [v0.13 RC2 notes](https://reactjs.org/blog/2015/03/03/react-v0.13-rc2.html#react.cloneelement) for more details.

 * New `ref` style, allowing a callback to be used in place of a name: `<Photo ref={(c) => this._photo = c} />` allows you to reference the component with `this._photo` (as opposed to `ref="photo"` which gives `this.refs.photo`).
 * `this.setState()` can now take a function as the first argument for transactional state updates, such as `this.setState((state, props) => ({count: state.count + 1}));` – this means that you no longer need to use `this._pendingState`, which is now gone.

+Using Creative Commons Public Licenses
+
+Creative Commons public licenses provide a standard set of terms and
+conditions that creators and other rights holders may use to share
+original works of authorship and other material subject to copyright
+and certain other rights specified in the public license below. The
+following considerations are for informational purposes only, are not
+exhaustive, and do not form part of our licenses.
+
+     Considerations for licensors: Our public licenses are
+     intended for use by those authorized to give the public
+     permission to use material in ways otherwise restricted by
+     copyright and certain other rights. Our licenses are
+     irrevocable. Licensors should read and understand the terms
+     and conditions of the license they choose before applying it.
+     Licensors should also secure all rights necessary before
+     applying our licenses so that the public can reuse the
+     material as expected. Licensors should clearly mark any
+     material not subject to the license. This includes other CC-
+     licensed material, or material used under an exception or
+     limitation to copyright. More considerations for licensors:
+	wiki.creativecommons.org/Considerations_for_licensors
+
+     Considerations for the public: By using one of our public
+     licenses, a licensor grants the public permission to use the
+     licensed material under specified terms and conditions. If
+     the licensor's permission is not necessary for any reason--for
+     example, because of any applicable exception or limitation to
+     copyright--then that use is not regulated by the license. Our
+     licenses grant only permissions under copyright and certain
+     other rights that a licensor has authority to grant. Use of
+     the licensed material may still be restricted for other
+     reasons, including because others have copyright or other
+     rights in the material. A licensor may make special requests,
+     such as asking that all changes be marked or described.
+     Although not required by our licenses, you are encouraged to
+     respect those requests where reasonable. More_considerations

+
+  h. Licensor means the individual(s) or entity(ies) granting rights
+     under this Public License.
+
+  i. Share means to provide material to the public by any means or

+     resulting from Directive 96/9/EC of the European Parliament and of
+     the Council of 11 March 1996 on the legal protection of databases,
+     as amended and/or succeeded, as well as other essentially
+     equivalent rights anywhere in the world.
+
+  k. You means the individual or entity exercising the Licensed Rights
+     under this Public License. Your has a corresponding meaning.
+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+       4. If You Share Adapted Material You produce, the Adapter's
+          License You apply must not prevent recipients of the Adapted
+          Material from complying with this Public License.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material; and
+
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

@@ -6,70 +6,60 @@ React is a JavaScript library for building user interfaces.
 * **Component-Based:** Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep state out of the DOM.
 * **Learn Once, Write Anywhere:** We don't make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React can also render on the server using Node and power mobile apps using [React Native](https://facebook.github.io/react-native/).

-
-## Installation
-
-React has been designed for gradual adoption from the start, and **you can use as little or as much React as you need**:
-
-* Use [Online Playgrounds](https://reactjs.org/docs/getting-started.html#online-playgrounds) to get a taste of React.
-* [Add React to a Website](https://reactjs.org/docs/add-react-to-a-website.html) as a `<script>` tag in one minute.
-* [Create a New React App](https://reactjs.org/docs/create-a-new-react-app.html) if you're looking for a powerful JavaScript toolchain.
-
-You can use React as a `<script>` tag from a [CDN](https://reactjs.org/docs/cdn-links.html), or as a `react` package on [npm](https://www.npmjs.com/).
-
-## Documentation
-
-You can find the React documentation [on the website](https://reactjs.org/docs).  
-
-Check out the [Getting Started](https://reactjs.org/docs/getting-started.html) page for a quick overview.

-The documentation is divided into several sections:
-
-* [Tutorial](https://reactjs.org/tutorial/tutorial.html)

+React is available as the `react` package on [npm](https://www.npmjs.com/). It is also available on a [CDN](https://facebook.github.io/react/docs/installation.html#using-a-cdn).
+
+React is flexible and can be used in a variety of projects. You can create new apps with it, but you can also gradually introduce it into an existing codebase without doing a rewrite.
+
+The recommended way to install React depends on your project. Here you can find short guides for the most common scenarios:
+
+* [Trying Out React](https://facebook.github.io/react/docs/installation.html#trying-out-react)
+* [Creating a Single Page Application](https://facebook.github.io/react/docs/installation.html#creating-a-single-page-application)
+* [Adding React to an Existing Application](https://facebook.github.io/react/docs/installation.html#adding-react-to-an-existing-application)
