+# redux-doctitle
+
+Redux middleware for managing document title.
+
+## Installation
+
+redux-doctitle requires **Redux 3.0 or later**.
+
+```
+npm install --save-dev redux-doctitle
+```
+
+This assumes that you’re using [npm](http://npmjs.com/) package manager with a
+module bundler like [Webpack](https://webpack.js.org/) or
+[Browserify](http://browserify.org/).
+
+## Usage
+
+In order to use redux-doctitle in your React components you need to install the
+middleware, first.
+
+```
+import {applyMiddleware, createStore} from "redux";
+import {documentTitleMiddlewareFactory} from "redux-doctitle";
+
+const documentTitleMiddleware = documentTitleMiddlewareFactory(["Example"]);
+const store = createStore(
+  reducer, initialState, applyMiddleware(documentTitleMiddleware)
+);
+```
+
+Once this is done, you can use the provided action to change document title
+from your React components.
+
+```
+import PropTypes from "prop-types";
+import React from "react";
+import {connect} from "react-redux";
+import {bindActionCreators} from "redux";
+import {setDocumentTitle} from "redux-doctitle";
+
+class HelloWorldComponent extends React.Component {
+  componentDidMount () {
+    this.props.actions.setDocumentTitle("Hello, World!");
+  }
+  render () {
+    return <div>Hello, World!</div>;
+  }
+}
+
+HelloWorldComponent.propTypes = {
+  actions: PropTypes.shape({
+    setDocumentTitle: PropTypes.func.isRequired
+  });
+};
+
+const mapStateToProps = (state, props) => {
+  return {};
+};
+
+const mapDispatchToProps = (dispatch, props) => {
+  const actions = bindActionCreators(
+    {
+      setDocumentTitle: setDocumentTitle
+    },
+    dispatch
+  );
+};
+
+const reduxContainer = connect(
+  mapStateToProps, mapDispatchToProps
+)(HelloWorldComponent);
+
+export default reduxContainer;
+```
+
+## API
+
+### `documentMiddlewareFactory(defaultTitleParts = [])`
+
+This is the middleware factory function. The *defaultTitleParts* argument is an
+optional array of title parts which will be appended to custom titles set
+through the `setDocumentTitle` action creator. If it's ommited, nothing will be
+appended.
+
+Returns Redux-compatible middleware function.
+
+### `setDocumentTitle(title = "")`
+
+This is the action creator that allows changing the document title.
+
+Returns Redux action.
+
+## Development
+
+To bootstrap the development environment, clone the repo and run `npm install`
+from the root directory.
+
+The `package.json` file provides the following scripts:
+
+* `build` - builds the library modules (minified and development with source
+  map),
+* `dev` - starts Webpack watcher configured to build development library,
+* `lint` - performs an eslint run over the source code,
+* `test` - performs a single test run,
+* `test:watch` - starts karma with watcher.
+
+**NOTE**: Tests require *Chromium* to be installed and available in the path.
+Consult
+[karma-chrome-launcher](https://github.com/karma-runner/karma-chrome-launcher)
+docs for more info.
+
+## Contributing
+
+If you think you found a bug or want to send a patch, feel free to contact
+me through e-mail.
+
+If you're sending a patch, make sure it passes eslint checks and is tested.
