 # Install
 
-Installing the latest published package on a 3rd party app is as simple as running `npm i @frontify/frontify-authenticator` and requiring the main class either via CommonJs or as an ES module.
+There are three possible ways of installing or requiring the Frontify Authenticator v2.

+## NPM

-There is a require/import example prepared on `src/local.ts` for added convienience simulating an end user import. To try it out, you simply need to run the `npm run local` command on the package root location.
+## CDN
+
+Alternatively, in case you're not relying on npm packages in your web app, you can also require the minified JS script directly by using a CDN such as UPAKG. You can find the latest [Frontify Authenticator v2 source code](https://unpkg.com/@frontify/frontify-authenticator@latest/dist/index.js) and import it to your project you by requiring it via a `<script>` HTML element.
+
+```
+<script src="https://unpkg.com/@frontify/frontify-authenticator@latest/dist/index.js"></script>
+```
+
+You may want to require a specific version. To do so you only have to change the word `latest` with the specific version you wish to use (ie. v2.0.0).
+
+To make use of the available methods in the script all you have to do is use the `FrontifyAuthenticator` object reference attached to the `window`.
+
+Example:
+
+```
+FrontifyAuthenticator.authorize(...);
+```
+
+or
+
+```
+window.FrontifyAuthenticator.authorize(...);
+```
+
+## LOCAL
+
+To install any package locally doesn't differ greatly from the CDN use case. You can use the [link mentioned above](https://unpkg.com/@frontify/frontify-authenticator@latest/dist/index.js) to download the file contents, save it to your local instance and require via `<script>` HTML element making the `src` address point to your local file.
+
+```
+<script src="<PATH_TO_FILE>/<FILENAME>.js"></script>
+```
 
-# Build
+Like mentioned in the CDN case, if may want to require a specific version, all you have to do is change the word `latest` with the specific version you wish to use (ie. v2.0.0).
 
-To perform a new build simply run `npm run build` in the application root folder. This will regenerate the `dist` folder contents with the production ready typescript compiled files.
+You must be aware that, in this case, the latest code won't be automatically updated so it relies on manual downloads everytime you want to have a new version come into effect within your web app.
