+Query Post Formats
+================
+
+`` is a React component used in managing network requests for post formats.
+
+## Usage
+
+Render the component, passing `siteId`. It does not accept any children, nor does it render any elements to the page. You can use it adjacent to other sibling components which make use of the fetched data made available through the global application state.
+
+```jsx
+import React from 'react';
+import QueryPostFormats from 'components/data/query-post-formats';
+import MyPostFormatsListItem from './list-item';
+
+export default function MyPostFormatsList( { postFormats } ) {
+ return (
+
+
+ { postFormats.map( ( label, id ) => {
+ return (
+
+ );
+ } }
+
+ );
+}
+```
+
+## Props
+
+### `siteId`
+
+
+ Type | Number |
+ Required | Yes |
+
+
+The site ID for which post formats should be requested.

+Post Formats
+===============
+
+A module for managing post formats.
+
+## Actions
+
+Used in combination with the Redux store instance `dispatch` function, actions can be used in manipulating the current global state.
+
+### `requestPostFormats( siteId: number )`
+
+Get a list of supported post formats for a given site.
+
+```js
+import { requestPostFormats } from 'state/post-formats/actions';
+
+requestPostFormats( 12345678 );
+```
+
+## Reducer
+
+Data from the aforementioned actions is added to the global state tree, under `postFormats`, with the following structure:
+
+```js
+state.postFormats = {
+ requesting: {
+ 12345678: false,
+ 87654321: true
+ },
+ items: {
+ 12345678: {
+ image: 'Image',
+ video: 'Video'
+ },
+ 87654321: {
+ status: 'Status'
+ }
+ }
+}
+```
+
+## Selectors are intended to assist in extracting data from the global state tree for consumption by other modules.
+
+#### `isRequestingPostFormats`
+
+Returns true if post formats are currently fetching for the given site ID.
+
+```js
+import { isRequestingPostFormats } from 'state/post-formats/selectors';
+
+const isRequesting = isRequestingPostFormats( state, 12345678 );
+```
+
+#### `getPostFormats`
+
+Returns an array of all supported site formats for the given site ID.
+
+```js
+import { getPostFormats } from 'state/post-formats/selectors';
+
+const postFormats = getPostFormats( state, 12345678 );
+```
