-# v5.0.0
-
-The main theme of the v5.0.0 release is an improved developer/user experience with OpenLayers. Toward this end, we have reworked the library as a set of ES Modules, completely removing any dependency on the Closure Compiler, and improving compatibility with mainstream module bundlers.
-
-See the [hosted examples](https://openlayers.org/en/latest/examples/), [API docs](https://openlayers.org/en/latest/apidoc/), and [bundle tutorial](https://openlayers.org/en/latest/doc/tutorials/bundle.html) for the new syntax, but basic usage looks like this:
-
-```js
-import 'ol/ol.css';
-import {Map, View} from 'ol';
-import TileLayer from 'ol/layer/Tile';
-import OSM from 'ol/source/OSM';
-
-const map = new Map({
-  target: 'map',
-  layers: [
-    new TileLayer({
-      source: new OSM()
-    })
-  ],
-  view: new View({
-    center: [0, 0],
-    zoom: 0
-  })
-});
-```
-
-See below for specific notes on upgrading from 4.x releases.  We'll be working on updating the website with improved documentation and examples.  Take a look at the issue tracker if you're interested in contributing.
-
-### Upgrade Notes
-
-#### Renamed `ol/source/TileUTFGrid` to `ol/source/UTFGrid`
-
-The module name is now `ol/source/UTFGrid` (`ol.source.UTFGrid` in the full build).
-
-#### Renaming of the `defaultDataProjection` in the options and property of the `ol/format/Feature` class and its subclasses
-
-The `defaultDataProjection` option is now named `dataProjection`. The protected property available on the class is also renamed.
-
-#### `transition` option of `ol/source/VectorTile` is ignored
-
-The `transition` option to get an opacity transition to fade in tiles has been  disabled for `ol/source/VectorTile`. Vector tiles are now always rendered without an opacity transition.
-
-#### `ol/style/Fill` with `CanvasGradient` or `CanvasPattern`
-
-The origin for gradients and patterns has changed from the top-left corner of the extent of the geometry being filled to 512 css pixel increments from map coordinate `[0, 0]`. This allows repeat patterns to be aligned properly with vector tiles. For seamless repeat patterns, width and height of the pattern image must be a factor of two (2, 4, 8, ..., 512).
-
-#### Removal of the renderer option for maps
-
-The `renderer` option has been removed from the `Map` constructor.  The purpose of this change is to avoid bundling code in your application that you do not need.  Previously, code for both the Canvas and WebGL renderers was included in all applications - even though most people only use one renderer.  The `Map` constructor now gives you a Canvas (2D) based renderer.  If you want to try the WebGL renderer, you can import the constructor from `ol/WebGLMap`.
-
-Old code:
-```js
-import Map from 'ol/Map';
-
-const canvasMap = new Map({
-  renderer: ['canvas']
-  // other options...
-});
-
-const webglMap = new Map({
-  renderer: ['webgl']
-  // other options...
-});
-```
-
-New code:
-```js
-import Map from 'ol/Map';
-import WebGLMap from 'ol/WebGLMap';
-
-const canvasMap = new Map({
-  // options...
-});
-
-const webglMap = new WebGLMap({
-  // options...
-});
-```
-
-#### Removal of ol.FeatureStyleFunction
-
-The signature of the vector style function passed to the feature has changed. The function now always takes the `feature` and the `resolution` as arguments, the `feature` is no longer bound to `this`.
-
-Old code:
-```js
-feature.setStyle(function(resolution) {
-  var text = this.get('name');
-  ...
-});
-```
-
-New code:
-```js
-feature.setStyle(function(feature, resolution) {
-  var text = feature.get('name');
-  ...
-});
-```
-
-#### Changed behavior of the `Draw` interaction
-
-For better drawing experience, two changes were made to the behavior of the Draw interaction:
-
- 1. On long press, the current vertex can be dragged to its desired position.
- 2. On touch move (e.g. when panning the map on a mobile device), no draw cursor is shown, and the geometry being drawn is not updated. But because of 1., the draw cursor will appear on long press. Mouse moves are not affected by this change.
-
-#### Changes in proj4 integration
-
-Because relying on a globally available proj4 is not practical with ES modules, we have made a change to the way we integrate proj4:
-
- * The `setProj4()` function from the `ol/proj` module was removed.
- * A new `ol/proj/proj4` module with a `register()` function was added. Regardless of whether the application imports `proj4` or uses a global `proj4`, this function needs to be called with the proj4 instance as argument whenever projection definitions were added to proj4's registry with (`proj4.defs`).
-
-It is also recommended to no longer use a global `proj4`. Instead,
-
-    npm install proj4
-
-and import it:
-
-```js
-import proj4 from 'proj4';
-```
-
-Applications can be updated by importing the `register` function from the `ol/proj/proj4` module
-
-```js
-import {register} from 'ol/proj/proj4'
-```
-
-and calling it before using projections, and any time the proj4 registry was changed by `proj4.defs()` calls:
-
-```js
-register(proj4);
-```
-
-#### Removal of logos
-
-The map and sources no longer accept a `logo` option.  Instead, if you wish to append a logo to your map, add the desired markup directly in your HTML.  In addition, you can use the `attributions` property of a source to display arbitrary markup per-source with the attribution control.
-
-#### Replacement of `ol/Sphere` constructor with `ol/sphere` functions
-
-The `ol/Sphere` constructor has been removed.  If you were using the `getGeodesicArea` method, use the `getArea` function instead.  If you were using the `haversineDistance` method, use the `getDistance` function instead.
-
-Examples before:
-```js
-// using ol@4
-import Sphere from 'ol/sphere';
-
-var sphere = new Sphere(Sphere.DEFAULT_RADIUS);
-var area = sphere.getGeodesicArea(polygon);
-var distance = sphere.haversineDistance(g1, g2);
-```
-
-Examples after:
-```js
-// using ol@5
-import {circular as circularPolygon} from 'ol/geom/Polygon';
-import {getArea, getDistance} from 'ol/sphere';
-
-var area = getArea(polygon);
-var distance = getDistance(g1, g2);
-var circle = circularPolygon(center, radius);
-```
-
-#### New signature for the `circular` function for creating polygons
-
-The `circular` function exported from `ol/geom/Polygon` no longer requires a `Sphere` as the first argument.
-
-Example before:
-```js
-// using ol@4
-import Polygon from 'ol/geom/polygon';
-import Sphere from 'ol/sphere';
-
-var poly = Polygon.circular(new Sphere(Sphere.DEFAULT_RADIUS), center, radius);
-```
-
-Example after:
-```js
-// using ol@5
-import {circular as circularPolygon} from 'ol/geom/Polygon';
-
-var poly = circularPolygon(center, radius);
-```
-
-#### Removal of optional this arguments.
-
-The optional this (i.e. opt_this) arguments were removed from the following methods. Please use closures, the es6 arrow function or the bind method to achieve this effect (Bind is explained here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind).
-
-* Collection#forEach
-* geom/LineString#forEachSegment
-* Observable#on, #once, #un
-* Map#forEachLayerAtPixel
-* source/TileUTFGrid#forDataAtCoordinateAndResolution
-* source/Vector#forEachFeature, #forEachFeatureInExtent, #forEachFeatureIntersectingExtent
-
-
-#### `Map#forEachLayerAtPixel` parameters have changed
- 
-If you are using the layer filter, please note that you now have to pass in the layer filter via an `AtPixelOptions` object. If you are not using the layer filter the usage has not changed.
-
-Old syntax:
-```
-    map.forEachLayerAtPixel(pixel, callback, callbackThis, layerFilterFn, layerFilterThis);
-```
-
-New syntax:
-
-```
-    map.forEachLayerAtPixel(pixel, callback, {
-        layerFilter: layerFilterFn
-    });
-```
-
-To bind a function to a this, please use the bind method of the function (See: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind).
-
-This change is due to the introduction of the `hitTolerance` parameter which can be passed in via this `AtPixelOptions` object, too.

-# v5.1.0
-
-The 5.1 release adds a few new features a handful of fixes.  You should be able to upgrade without any additional work.  See the one note below regarding `null` geometry coordinates.
-
-We're working toward type checking with TypeScript.  This will complete our move away from using the Closure Compiler for type checking and compilation.  We're excited about the improved experience for application developers and will highlight some of the benefit in upcoming releases.
-
-### Upgrade Notes
-
-#### Geometry constructor and `setCoordinates` no longer accept `null` coordinates
-
-Geometries (`ol/geom/*`) now need to be constructed with valid coordinates (center for `ol/geom/Circle`) as first constructor argument. The same applies to the `setCoordinates()` (`setCenter() for `ol/geom/Circle`) method.

-# Introduction
-
-## Objectives
-
-OpenLayers is a modular, high-performance, feature-packed library for displaying and interacting with maps and geospatial data.
-
-The library comes with built-in support for a wide range of commercial and free image and vector tile sources, and the most popular open and proprietary vector data formats. With OpenLayers's map projection support, data can be in any projection.
-
-## Public API
-
-OpenLayers is available as [`ol` npm package](https://npmjs.com/package/ol), which provides all modules of the officially supported [API](../../apidoc).
-
-## Renderers and Browser Support
-
-By default, OpenLayers uses a performance optimized Canvas renderer. An experimental WebGL renderer (without text rendering support) is also avaialble.
-
-OpenLayers runs on all modern browsers that support [HTML5](https://html.spec.whatwg.org/multipage/) and [ECMAScript 5](http://www.ecma-international.org/ecma-262/5.1/). This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, [polyfills](http://polyfill.io), the application bundle needs to be transpiled (e.g. using [Babel](https://babeljs.io)) and bundled with polyfills for `requestAnimationFrame`, `Element.prototype.classList` and `URL`.
-
-The library is intended for use on both desktop/laptop and mobile devices, and supports pointer and touch interactions.
-
-## Module and Naming Conventions
-
-OpenLayers modules with CamelCase names provide classes as default exports, and may contain additional constants or functions as named exports:
-
-```js
-import Map from 'ol/Map';
-import View from 'ol/View';
-```
-
-Class hierarchies grouped by their parent are provided in a subfolder of the package, e.g. `layer/`.
-
-For convenience, these are also available as named exports, e.g.
-
-```js
-import {Map, View} from 'ol';
-import {Tile, Vector} from 'ol/layer';
-```
-
-In addition to these re-exported classes, modules with lowercase names also provide constants or functions as named exports:
-
-```js
-import {inherits} from 'ol';
-import {fromLonLat} from 'ol/proj';
-```

+title: Basic project setup using NPM and Browserify
+layout: doc.hbs
+---
+
+# Introduction
+
+When going beyond modifying existing examples you might be looking for a way to setup your own code with dependency management together with external dependencies like OpenLayers.
+
+This tutorial serves as a suggested project setup using NPM and Browserify for the most basic needs. There are several other options, and in particular you might be interested in a more modern one (ES2015) [using Webpack with OpenLayers](https://gist.github.com/tschaub/79025aef325cd2837364400a105405b8).
+
+## Initial steps
+
+Create a new empty directory for your project and navigate to it by running `mkdir new-project && cd new-project`. Initialize your project using `npm init` and answer the questions asked.
+
+Add OpenLayers as dependency to your application with `npm install --save ol`.
+
+At this point you can ask NPM to add required development dependencies by running
+```
+npm install --save-dev cssify browserify cssify http-server uglify-js watchify
+npm install --save-dev babelify babel-plugin-transform-es2015-modules-commonjs
+```
+We will be using `cssify` to include the css definitions required by OpenLayers in our bundle. `watchify`, `http-server` and `uglify-js` are used to monitor for changes and to build into a minified bundle. `babelify` and `babel-plugin-transform-es2015-modules-commonjs` are used to make the `ol` package, which was created using ES2015 modules, work with CommonJS.
+
+## Application code and index.html
+
+Place your application code in `index.js`. Here is a simple starting point:
+
+```js
+require('ol/ol.css');
+var ol_Map = require('ol/map').default;
+var ol_layer_Tile = require('ol/layer/tile').default;
+var ol_source_OSM = require('ol/source/osm').default;
+var ol_View = require('ol/view').default;
+
+var map = new ol_Map({
+  target: 'map',
+  layers: [
+    new ol_layer_Tile({
+      source: new ol_source_OSM()
+    })
+  ],
+  view: new ol_View({
+    center: [0, 0],
+    zoom: 0
+  })
+});
+```
+
+You will also need an `ìndex.html` file that will use your bundle. Here is a simple example:
+
+```html
+<!DOCTYPE html>
+<html>
+  <head>
+    <meta charset="utf-8">
+    <title>Using Browserify with OpenLayers</title>
+    <style>
+      #map {
+        width: 400px;
+        height: 250px;
+      }
+    </style>
+  </head>
+  <body>
+    <div id="map"></div>
+    <script src="bundle.js"></script>
+  </body>
+</html>
+```
+
+## Creating a bundle
+
+With simple scripts you can introduce the commands `npm run build` and `npm start` to manually build your bundle and watch for changes, respectively. Add the following to the script section in `package.json`:
+
+```json
+"scripts": {
+  "start": "watchify index.js -g cssify --outfile bundle.js & http-server",
+  "build": "browserify -g cssify index.js | uglifyjs --compress --output bundle.js"
+}
+```
+Now to test your application open http://localhost:8080/ in your browser. `watchify` will update `bundle.js` whenever you change something. You simply need to reload the page in your browser to see the changes.
+```
+$ npm start
+```
+
+Note that `bundle.js` will contain your application code and all dependencies used in your application. From OpenLayers, it only contains the required components.

-  "start": "parcel index.html",
-  "build": "parcel build --public-url . index.html"
-}
-```
-That's it. Now to run your application, enter
-
-    npm start
-
-in your console. To test your application, open http://localhost:1234/ in your browser. Whenever you change something, the page will reload automatically to show the result of your changes.
-
-Note that a single JavaScript file with all your application code and all dependencies used in your application has been created. From the OpenLayers package, it only contains the required components.
-
-To create a production bundle of your application, simply type
-
-    npm run build
-
-and copy the `dist/` folder to your production server.

 # Basic Concepts
 
 ## Map
-The core component of OpenLayers is the map (`Map`). It is rendered to a `target` container (e.g. a `div` element on the web page that contains the map). All map properties can either be configured at construction time, or by using setter methods, e.g. `setTarget()`.

 ```xml
 <div id="map" style="width: 100%, height: 400px"></div>
 <script>
-  import Map from 'ol/Map';
+  var map = new ol.Map({target: 'map'});
-
-  var map = new Map({target: 'map'});
 </script>
 ```
 
 ## View
-`Map` is not responsible for things like center, zoom level and projection of the map. Instead, these are properties of a `View` instance.
+`ol.Map` is not responsible for things like center, zoom level and projection of the map. Instead, these are properties of an `ol.View` instance.
 
 ```js
-  import View from 'ol/View';
+  map.setView(new ol.View({
-
-  map.setView(new View({
     center: [0, 0],
     zoom: 2
   }));
 ```
 
-A `View` also has a `projection`. The projection determines the coordinate system of the `center` and the units for map resolution calculations. If not specified (like in the above snippet), the default projection is Spherical Mercator (EPSG:3857), with meters as map units.

 The `zoom` option is a convenient way to specify the map resolution. The available zoom levels are determined by `maxZoom` (default: 28), `zoomFactor` (default: 2) and `maxResolution` (default is calculated in such a way that the projection's validity extent fits in a 256x256 pixel tile). Starting at zoom level 0 with a resolution of `maxResolution` units per pixel, subsequent zoom levels are calculated by dividing the previous zoom level's resolution by `zoomFactor`, until zoom level `maxZoom` is reached.
 
 
 ## Source
-To get remote data for a layer, OpenLayers uses `source/Source` subclasses. These are available for free and commercial map tile services like OpenStreetMap or Bing, for OGC sources like WMS or WMTS, and for vector data in formats like GeoJSON or KML.

+# Introduction
+
+## Objectives
+With version 3, the OpenLayers web mapping library was fundamentally redesigned. The widely used version 2 dates from the early days of Javascript development, and was increasingly showing its age. So it has been rewritten from the ground up to use modern design patterns.
+
+The initial release aims to support much of the functionality provided by version 2, with support for a wide range of commercial and free tile sources, and the most popular open-source vector data formats. As with version 2, data can be in any projection. The initial release also adds some additional functionality, such as the ability to easily rotate or animate maps.
+
+It is also designed such that major new features, such as displaying 3D maps, or using WebGL to quickly display large vector data sets, can be added in later releases.
+
+## Public API
+Using the advanced optimizations of the Closure Compiler means that properties and methods are renamed – `longMeaningfulName` might become `xB` – and so are effectively unusable in applications using the library. To be usable, they have to be explicitly `exported`. This means the exported names, those not renamed, effectively become the public API of the library. These __exportable__ properties and methods are marked in the source, and documented in the [API docs](../../apidoc). This is the officially supported API of the library. A build containing all these exportable names is known as a __full build__. A hosted version of this is available, which can be used by any application.
+
+## Custom Builds
+Unlike in, say, Node, where a module's exports are fixed in the source, with Closure Compiler, exports can be defined at compile time. This makes it easy to create builds that are customized to the needs of a particular site or application: a __custom build__ only exports those properties and methods needed by the site or application. As the full build is large, and will probably become larger as new features are added to the API, it's recommended that sites create a custom build for production software.
+
+## Renderers and Browser Support
+The library currently includes two renderers: Canvas and WebGL. Both of them support both raster data from tile/image servers, and vector data; WebGL however does not support labels. Clearly only those browsers that [support Canvas](http://caniuse.com/canvas) can use the Canvas renderer. Equally, the WebGL renderer can only be used on those devices and [browsers](http://caniuse.com/webgl) that support WebGL.
+
+OpenLayers runs on all modern browsers that support [HTML5](https://html.spec.whatwg.org/multipage/) and [ECMAScript 5](http://www.ecma-international.org/ecma-262/5.1/). This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, [polyfills](http://polyfill.io) for `requestAnimationFrame` and `Element.prototype.classList` are required, and using the KML format requires a polyfill for `URL`.
+
+The library is intended for use on both desktop/laptop and mobile devices.
+
+## Objects and Naming Conventions
+The top-level namespace is `ol` (basically, `var ol = {};`). Subdivisions of this are:
+
+* further namespaces, such as `ol.layer`; these have a lower-case initial
+* simple objects containing static properties and methods, such as `ol.easing`; these also have a lower-case initial
+* types, which have an upper-case initial. These are mainly 'classes', which here means a constructor function with prototypal inheritance, such as `ol.Map` or `ol.layer.Vector` (the Vector class within the layer namespace). There are however other, simpler, types, such as `ol.Extent`, which is an array.
+
+Class namespaces, such as `ol.layer` have a base class type with the same name, such as `ol.layer.Layer`. These are mainly abstract classes, from which the other subclasses inherit.
+
+Source files are similarly organised, with a directory for each class namespace. Names are however all lower-case, for example, `ol/layer/vector.js`.
+
+OpenLayers follows the convention that the names of private properties and methods, that is, those that are not part of the API, end in an underscore. In general, instance properties are private and accessed using accessors.

+Alternatively, a custom target TileGrid can be constructed manually and set on the source instance using `ol.source.TileImage#setTileGridForProjection(projection, tilegrid)`.

 ### Resolution calculation
 When determining source tiles to load, the ideal source resolution needs to be calculated.
-The `ol/reproj~calculateSourceResolution(sourceProj, targetProj, targetCenter, targetResolution)` function calculates the ideal value in order to achieve pixel mapping as close as possible to 1:1 during reprojection, which is then used to select proper zoom level from the source.
+The `ol.reproj.calculateSourceResolution(sourceProj, targetProj, targetCenter, targetResolution)` function calculates the ideal value in order to achieve pixel mapping as close as possible to 1:1 during reprojection, which is then used to select proper zoom level from the source.
 
 It is, however, generally not practical to use the same source zoom level for the whole target zoom level -- different projections can have significantly different resolutions in different parts of the world (e.g. polar regions in EPSG:3857 vs EPSG:4326) and enforcing a single resolution for the whole zoom level would result in some tiles being scaled up/down, possibly requiring a huge number of source tiles to be loaded.
 Therefore, the resolution mapping is calculated separately for each reprojected tile (in the middle of the tile extent).
