 <h1>Overview</h1><p>The library is made to help to detect what browser your user has and gives you a convenient API to filter the users somehow depending on their browsers.</p>
-<p><em>Please, note that this is an alpha version. Check out the <a href="https://github.com/lancedikson/bowser/tree/v1.x">1.x</a> branch for a stable version.</em></p>
-<p><strong>Changes of version 2.0</strong>
-The upcoming 2.0 version has drastically changed API. All available methods can be found in the <code>docs</code> folder from now on and on a webpage soon.</p>
-<h1>Use cases</h1><p>First of all, require the library. This is a UMD Module, so it will work for AMD, Typescript and CommonJS module systems.</p>
+<h3>⚠️ Version 2.0 breaking changes ⚠️</h3><p>Version 2.0 has drastically changed the API. All available methods are on the <a href="https://lancedikson.github.io/bowser/docs">docs page</a>.</p>
+<p><em>For legacy code, check out the <a href="https://github.com/lancedikson/bowser/tree/v1.x">1.x</a> branch and install it through <code>npm install bowser@1.9.4</code>.</em></p>

 <p>In case you don't use your own <code>babel-polyfill</code> you may need to have pre-built bundle with all needed polyfills.
 So, for you it's suitable to require bowser like this: <code>require('bowser/bundled')</code>.
 As the result, you get a ES5 version of bowser with <code>babel-polyfill</code> bundled together.</p>
 <p>You may need to use the source files, so they will be available in the package as well.</p>
 <h2>Browser props detection</h2><p>Often we need to pick users' browser properties such as the name, the version, the rendering engine and so on. Here is an example how to do it with Bowser:</p>
