-To keep this project manageable for maintainers, we ask you to please check all boxes below before submitting an issue.
-
- [ ] I am submitting a bug or feature request, not a usage question. Go to https://stackoverflow.com/questions/tagged/openlayers for questions.
- [ ] I have searched GitHub to see if a similar bug or feature request has already been reported.
- [ ] I have verified that the issue is present in the latest version of OpenLayers (see 'LATEST' on https://openlayers.org/).
- [ ] If reporting a bug, I have created a [CodePen](https://codepen.io) or prepared a stack trace (using the latest version and unminified code, so e.g. `ol-debug.js`, not `ol.js`) that shows the issue.

 ## Getting Started

-Use one of the following methods to use OpenLayers in your project:
-
-* For use with webpack, Rollup, Browserify, or other module bundlers, install the [`ol` package](https://www.npmjs.com/package/ol):
-    ```
-    npm install ol
-    ```
-
-* If you just want to add a `<script>` tag to test things out, you can link directly to one of the full builds from [cdnjs](https://cdnjs.com/libraries/openlayers) (not recommended for production)
-
-* For use with Closure Library (rare), install the [`openlayers` package](https://npmjs.com/package/openlayers) and read the [tutorial](http://openlayers.org/en/latest/doc/tutorials/closure.html).
+- Download the [latest release](https://openlayers.org/download/)
+- Install with npm: `npm install openlayers`
+- Clone the repo: `git clone git@github.com:openlayers/openlayers.git`

 ## Upgrade notes

-### v4.5.0
-
-#### Removed GeoJSON crs workaround for GeoServer
-
-Previous version of GeoServer returned invalid crs in GeoJSON output.  The workaround in `ol.format.GeoJSON` used to read this crs code is now removed.
-
-#### Deprecation of `ol.Attribution`
-
-`ol.Attribution` is deprecated and will be removed in the next major version.  Instead, you can construct a source with a string attribution or an array of strings.  For dynamic attributions, you can provide a function that gets called with the current frame state.
-
-Before:
-```js
-var source = new ol.source.XYZ({
-  attributions: [
-    new ol.Attribution({html: 'some attribution'})
-  ]
-});
-```
-
-After:
-```js
-var source = new ol.source.XYZ({
-  attributions: 'some attribution'
-});
-```
-
-In addition to passing a string or an array of strings for the `attributions` option, you can also pass a function that will get called with the current frame state.
-```js
-var source = new ol.source.XYZ({
-  attributions: function(frameState) {
-    // inspect the frame state and return attributions
-    return 'some attribution'; // or ['multiple', 'attributions'] or null
-  }
-});
-```
-
-### v4.4.0
-
-#### Behavior change for polygon labels
-
-Polygon labels are now only rendered when the label does not exceed the polygon at the label position. To get the old behavior, configure your `ol.style.Text` with `exceedLength: true`.
-
-#### Minor change for custom `tileLoadFunction` with `ol.source.VectorTile`
-
-It is no longer necessary to set the projection on the tile. Instead, the `readFeatures` method must be called with the tile's extent as `extent` option and the view's projection as `featureProjection`.
-
-Before:
-```js
-tile.setLoader(function() {
-  var data = // ... fetch data
-  var format = tile.getFormat();
-  tile.setFeatures(format.readFeatures(data));
-  tile.setProjection(format.readProjection(data));
-  // uncomment the line below for ol.format.MVT only
-  //tile.setExtent(format.getLastExtent());
-});
-```
-
-After:
-```js
-tile.setLoader(function() {
-  var data = // ... fetch data
-  var format = tile.getFormat();
-  tile.setFeatures(format.readFeatures(data, {
-    featureProjection: map.getView().getProjection(),
-    // uncomment the line below for ol.format.MVT only
-    //extent: tile.getExtent()
-  }));
-);
-```
-
-#### Deprecation of `ol.DeviceOrientation`
-
-`ol.DeviceOrientation` is deprecated and will be removed in the next major version.
-The device-orientation example has been updated to use the (gyronorm.js)[https://github.com/dorukeker/gyronorm.js] library.
-
-
-### v4.3.0
-
-#### `ol.source.VectorTile` no longer requires a `tileGrid` option
-
-By default, the `ol.source.VectorTile` constructor creates an XYZ tile grid (in Web Mercator) for 512 pixel tiles and assumes a max zoom level of 22.  If you were creating a vector tile source with an explicit `tileGrid` option, you can now remove this.
-
-Before:
-```js
-var source = new ol.source.VectorTile({
-  tileGrid: ol.tilegrid.createXYZ({tileSize: 512, maxZoom: 22}),
-  url: url
-});
-```
-
-After:
-```js
-var source = new ol.source.VectorTile({
-  url: url
-});
-```
-
-If you need to change the max zoom level, you can pass the source a `maxZoom` option.  If you need to change the tile size, you can pass the source a `tileSize` option.  If you need a completely custom tile grid, you can still pass the source a `tileGrid` option.
-
-#### `ol.interaction.Modify` deletes with `alt` key only
-
-To delete features with the modify interaction, press the `alt` key while clicking on an existing vertex.  If you want to configure the modify interaction with a different delete condition, use the `deleteCondition` option.  For example, to allow deletion on a single click with no modifier keys, configure the interaction like this:
-```js
-var interaction = new ol.interaction.Modify({
-  source: source,
-  deleteCondition: function(event) {
-    return ol.events.condition.noModifierKeys(event) && ol.events.condition.singleClick(event);
-  }
-});
-```
-
-The motivation for this change is to make the modify, draw, and snap interactions all work well together.  Previously, the use of these interactions with the default configuration would make it so you couldn't reliably add new vertices (click with no modifier) and delete existing vertices (click with no modifier).
-
-#### `ol.source.VectorTile` no longer has a `tilePixelRatio` option
-
-The `tilePixelRatio` option was only used for tiles in projections with `tile-pixels` as units. For tiles read with `ol.format.MVT` and the default tile loader, or tiles with the default pixel size of 4096 pixels, no changes are necessary. For the very rare cases that do not fall under these categories, a custom `tileLoadFunction` now needs to be configured on the `ol.source.VectorTile`. In addition to calling `tile.setFeatures()` and `tile.setProjection()`, it also needs to contain code like the following:
-```js
-var extent = tile.getFormat() instanceof ol.format.MVT ?
-  tile.getLastExtent() :
-  [0, 0, tilePixelRatio * tileSize, tilePixelRatio * tileSize];
-tile.setExtent(extent);
-```

-# 4.3.0
-
-## Summary
-
-The v4.3.0 release includes features and fixes from 92 pull requests.
-
-#### New `map.getFeaturesAtPixel()` method
-
-When you want to get all features at a given pixel, use the new `map.getFeaturesAtPixel()` method.
-
-Before:
-```js
-var features = [];
-map.forEachFeatureAtPixel(pixel, function(feature) {
-  features.push(feature);
-});
-```
-
-After:
-```js
-var features = map.getFeaturesAtPixel(pixel);
-```
-
-#### `ol.Sphere` functions for spherical measures
-
-The new `ol.Sphere.getArea()` and `ol.Sphere.getLength()` methods can be used to calculate spherical measures on geometries.  This is the recommended over using the `geometry.getArea()` or `geometry.getLength()` methods.
-
-Bad:
-```js
-geometry.getArea();
-```
-
-Good:
-```js
-ol.Sphere.getArea(geometry);
-```
-
-#### `ol.interaction.DragAndDrop` can be configured with a vector source
-
-It is now possible to configure the drag and drop interaction with a vector source:
-
-```js
-var dragAndDrop = new ol.interaction.DragAndDrop({source: source});
-```
-
-Any dropped features will replace all existing features on the source.
-
-#### `ol.interaction.Modify` can be configured with a vector source
-
-It is now possible to configure the modify interaction with a vector source (in addition to a feature collection):
-
-```js
-var modify = new ol.interaction.Modify({source: source});
-```
-
-With this configuration, all features on the source are eligible for modification while the interaction is active.
-
-#### `ol.interaction.Modify` deletes with `alt` key only
-
-To delete features with the modify interaction, press the `alt` key while clicking on an existing vertex.  If you want to configure the modify interaction with a different delete condition, use the `deleteCondition` option.  For example, to allow deletion on a single click with no modifier keys, configure the interaction like this:
-```js
-var interaction = new ol.interaction.Modify({
-  source: source,
-  deleteCondition: function(event) {
-    return ol.events.condition.noModifierKeys(event) && ol.events.condition.singleClick(event);
-  }
-});
-```
-
-The motivation for this change is to make the modify, draw, and snap interactions all work well together.  Previously, the use of these interactions with the default configuration would make it so you couldn't reliably add new vertices (click with no modifier) and delete existing vertices (click with no modifier).
-
-#### `ol.source.VectorTile` no longer requires a `tileGrid` option
-
-By default, the `ol.source.VectorTile` constructor creates an XYZ tile grid (in Web Mercator) for 512 pixel tiles and assumes a max zoom level of 22.  If you were creating a vector tile source with an explicit `tileGrid` option, you can now remove this.
-
-Before:

-var source = new ol.source.VectorTile({
-  tileGrid: ol.tilegrid.createXYZ({tileSize: 512, maxZoom: 22}),
-  url: url
-});
-```
-
-After:
-```js
-var source = new ol.source.VectorTile({
-  url: url
-});
-```
-
-If you need to change the max zoom level, you can pass the source a `maxZoom` option.  If you need to change the tile size, you can pass the source a `tileSize` option.  If you need a completely custom tile grid, you can still pass the source a `tileGrid` option.
-

-```js
-var extent = tile.getFormat() instanceof ol.format.MVT ?
-  tile.getLastExtent() :
-  [0, 0, tilePixelRatio * tileSize, tilePixelRatio * tileSize];
-tile.setExtent(extent);
-```
-
-#### `ol.animate` now takes the shortest arc for rotation animation
-
-Usually rotation animations should animate along the shortest arc. There are rare occasions where a spinning animation effect is desired. So if you previously had something like
-```js
-map.getView().animate({
-  rotation: 2 * Math.PI,
-  duration: 2000
-});
-```
-we recommend to split the animation into two parts and use different easing functions. The code below results in the same effect as the snippet above did with previous versions:
-```js
-map.getView().animate({
-  rotation: Math.PI,
-  easing: ol.easing.easeIn
-}, {
-  rotation: 2 * Math.PI,
-  easing: ol.easing.easeOut
-});
-```

-## Summary
-
-The 4.4.0 release includes features and fixes from 80 pull requests, including first time contributions from @EduardoNogueira, @ath0mas, @f7o, @trevorblades, @viethang, and @wb14123.  There are some really nice rendering enhancements included in this release.  It is now possible to render labels along lines (see [#7239](https://github.com/openlayers/openlayers/pull/7239) for more detail) and polygon labels are only rendered if they fit within the polygon ([#7292](https://github.com/openlayers/openlayers/pull/7292)).  In addition, we now render tiles with an opacity transition, so tiled layers more gracefully fade in ([#7267](https://github.com/openlayers/openlayers/pull/7267)).
-
-### Upgrade notes
-
-#### Behavior change for polygon labels
-
-Polygon labels are now only rendered when the label does not exceed the polygon at the label position. To get the old behavior, configure your `ol.style.Text` with `exceedLength: true`.
-
-#### Minor change for custom `tileLoadFunction` with `ol.source.VectorTile`
-
-It is no longer necessary to set the projection on the tile. Instead, the `readFeatures` method must be called with the tile's extent as `extent` option and the view's projection as `featureProjection`.
-
-Before:
-```js
-tile.setLoader(function() {
-  var data = // ... fetch data
-  var format = tile.getFormat();
-  tile.setFeatures(format.readFeatures(data));
-  tile.setProjection(format.readProjection(data));
-  // uncomment the line below for ol.format.MVT only
-  //tile.setExtent(format.getLastExtent());
-});
-```
-
-After:
-```js
-tile.setLoader(function() {
-  var data = // ... fetch data
-  var format = tile.getFormat();
-  tile.setFeatures(format.readFeatures(data, {
-    featureProjection: map.getView().getProjection(),
-    // uncomment the line below for ol.format.MVT only
-    //extent: tile.getExtent()
-  }));
-);
-```
-
-#### Deprecation of `ol.DeviceOrientation`
-
-`ol.DeviceOrientation` is deprecated and will be removed in the next major version.
-The device-orientation example has been updated to use the (gyronorm.js)[https://github.com/dorukeker/gyronorm.js] library.

-# 4.5.0
-
-### Summary
-
-The 4.5 release includes enhancements and fixes from 50 or so pull requests.  Headlining this release, vector layers got a new `declutter` option that can be used to avoid overlapping labels.  See the [street labels example](http://openlayers.org/en/latest/examples/street-labels.html) for a demonstration of this feature.
-
-Please note that if you are using `closure-util` to build your OpenLayers based application, it is time to migrate to using the [`ol` package](https://www.npmjs.com/package/ol) and a module bundler like webpack.  OpenLayers has not had a dependency on the Closure Library since the [3.19 release](https://github.com/openlayers/openlayers/releases/tag/v3.19.0); and with the 5.0 release we will be moving completely away from `goog.require` and `goog.provide`, dropping support for `closure-util`, and going with ES modules for our sources.
-
-We will be adding details to the wiki about upcoming changes in 5.0 and tips on how to upgrade.  We'll likely have a few more 4.x releases before the 5.0 release.  But if you're interested in continuing to get feature enhancements in future releases, migrating to the `ol` package now will make the transition easier.
-
-### Upgrade notes
-
-#### Removed GeoJSON crs workaround for GeoServer
-
-Previous version of GeoServer returned invalid crs in GeoJSON output.  The workaround in `ol.format.GeoJSON` used to read this crs code is now removed.
-
-#### Deprecation of `ol.Attribution`
-
-`ol.Attribution` is deprecated and will be removed in the next major version.  Instead, you can construct a source with a string attribution or an array of strings.  For dynamic attributions, you can provide a function that gets called with the current frame state.
-
-Before:
-```js
-var source = new ol.source.XYZ({
-  attributions: [
-    new ol.Attribution({html: 'some attribution'})
-  ]
-});
-```
-
-After:
-```js
-var source = new ol.source.XYZ({
-  attributions: 'some attribution'
-});
-```
-
-In addition to passing a string or an array of strings for the `attributions` option, you can also pass a function that will get called with the current frame state.
-```js
-var source = new ol.source.XYZ({
-  attributions: function(frameState) {
-    // inspect the frame state and return attributions
-    return 'some attribution'; // or ['multiple', 'attributions'] or null
-  }
-});
-```

+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.

 # Compiling Application with Closure Compiler

-**Note**: When building an application with dependencies that are available as [npm](https://npmjs.com/) packages, it will probably be easier to use the [ol](https://npmjs.com/package/ol) package and follow the instructions there.
-
 The OpenLayers code uses the Closure Library, and it is compiled with the
 Closure Compiler. Using OpenLayers in an application does not require using
 Closure. But using Closure in an OpenLayers application is possible. And this
 is what this tutorial is about.

-When you want to include OpenLayers as separate script without bundling with your application, follow the [Creating custom builds](./custom-builds.html) tutorial instead.

 This tutorial will teach you how to set up an OpenLayers application based on
 the [`closure-util`](https://github.com/openlayers/closure-util) node package,

-/**
- * @classdesc
- * The map is the core component of OpenLayers. For a map to render, a view,
- * one or more layers, and a target container are needed:
- *
- *     var map = new ol.CanvasMap({
- *       view: new ol.View({
- *         center: [0, 0],
- *         zoom: 1
- *       }),
- *       layers: [
- *         new ol.layer.Tile({
- *           source: new ol.source.OSM()
- *         })
- *       ],
- *       target: 'map'
- *     });
- *
- * The above snippet creates a map using a {@link ol.layer.Tile} to display
- * {@link ol.source.OSM} OSM data and render it to a DOM element with the
- * id `map`.
- *
- * The constructor places a viewport container (with CSS class name
- * `ol-viewport`) in the target element (see `getViewport()`), and then two
- * further elements within the viewport: one with CSS class name
- * `ol-overlaycontainer-stopevent` for controls and some overlays, and one with
- * CSS class name `ol-overlaycontainer` for other overlays (see the `stopEvent`
- * option of {@link ol.Overlay} for the difference). The map itself is placed in
- * a further element within the viewport.
- *
- * Layers are stored as a `ol.Collection` in layerGroups. A top-level group is
- * provided by the library. This is what is accessed by `getLayerGroup` and
- * `setLayerGroup`. Layers entered in the options are added to this group, and
- * `addLayer` and `removeLayer` change the layer collection in the group.
- * `getLayers` is a convenience function for `getLayerGroup().getLayers()`.
- * Note that `ol.layer.Group` is a subclass of `ol.layer.Base`, so layers
- * entered in the options or added with `addLayer` can be groups, which can
- * contain further groups, and so on.
