 ## In a browser
 
-### Note, the browserify build has been deprecated. Please use a bundler like webpack or vite instead.
-
-Download the browser version from
-https://github.com/matrix-org/matrix-js-sdk/releases/latest and add that as a
-`<script>` to your page. There will be a global variable `matrixcs`
-attached to `window` through which you can access the SDK. See below for how to
-include libolm to enable end-to-end-encryption.

-The browser bundle supports recent versions of browsers. Typically this is ES2015
-or `> 0.5%, last 2 versions, Firefox ESR, not dead` if using

-
-Please check [the working browser example](examples/browser) for more information.
