 A polyfill for the Resize Observer API.

Handles non-delayed CSS transitions/animations and can optionally observe resizing of a `<textarea>` element along with changes caused by the `:hover` pseudo-class.

-You can also take minified bundles: `ResizeObserver.min.js` or `ResizeObserver.global.min.js`.
+**Note**: global versions (`index.global` and `dist/ResizeObserver.global`) and will be removed in the next major release.
 
 ## Configuration
 
 `ResizeObserver` class additionally implements following static accessor property:
 
 ### continuousUpdates
 
-By default things like resizing of a `<textarea>` element,  changes caused by the CSS `:hover` pseudo-class and delayed CSS transitions are not tracked. To handle them you can set `ResizeObserver.continuousUpdates = true` which in turn will start a continuous update cycle which runs every `100` milliseconds (as a RAF callback, of course). Keep in mind that this is going to affect the performance.

 ## Building and testing
 
-First make sure that you have all dependencies installed by running `npm install`. Then you can execute following tasks either with a gulp CLI or with the `npm run gulp` command.
-
-To build polyfill. This will create UMD bundles in the `dist` folder:
+To build polyfill. Creates UMD bundle in the `dist` folder:
 
 ```sh
-gulp build

 To run a code style test:
 ```sh
-gulp test:lint
+npm run test:lint
 ```
 
-Functional tests for all available browsers defined in `karma.config.js` file:

 ```sh
-gulp test:spec
+npm run test:spec
 ```
 
 To test in a browser that is not present in karmas' config file:
 ```sh
-gulp test:spec:custom
+npm run test:spec:custom
 ```
 
 Testing against a native implementation:
 ```sh
-gulp test:spec:native
+npm run test:spec:native
 ```
 
 **NOTE:** after you invoke `spec:native` and `spec:custom` commands head to the `http://localhost:9876/debug.html` page.
