 ## Prerequisites
-This package depends on `@angular v2.0.0` but it's highly recommended that you are running at least **`@angular v2.4.0`** and **`@angular/router v3.4.0`**. Older versions contain outdated dependencies, might produce errors.
+This package depends on `@angular v4.0.0`, and the **[master]** branch does no longer support `@angular v2.x.x`.
 
-Also, please ensure that you are using **`Typescript v2.1.6`** or higher.

-#### WARNING
+However, the [v0.2.x] branch keeps ongoing support for `@angular v2.x.x` - depending on `@angular v2.0.0`, and it's highly recommended that you are running at least **`@angular v2.4.0`** and **`@angular/router v3.4.0`**. Older versions (*especially `@angular/router v2.4.8`*) contain outdated dependencies, might produce errors.
 
-The pull request [#14327](https://github.com/angular/angular/pull/14327) on **`@angular v2.4.8`** and **`@angular v4.0.0-rc.1`**  introduced a severe error [#14588](https://github.com/angular/angular/issues/14588) which causes the app to fall into an infinite loop before bootstrapping.
+- If you're using `@angular v4.x.x`, use the latest release of `v0.4.x` (*[master] branch*).
+- If you're using `@angular v2.x.x`, use the latest release of `v0.2.x` (*[v0.2.x] branch*).
 
-In order to avoid issues, avoid using these versions of **Angular**.
+Also, please ensure that you are using **`Typescript v2.1.6`** or higher.
