 ## How to use
 
+**Prerequisites**: you need
+to [generate a TransferWise Personal API token](https://api-docs.transferwise.com/payouts#wise-payouts-api-documentation-api-access)
+to use this page's integration with TransferWise balances.
+
+### Download a release
+
+Changes are automatically built and pushed to the [GitHub Releases](https://github.com/StenAL/new-tab/releases) page
+where you can find ready-to-use artifacts in `.zip` and `.tar.gz` format. To set up the page:
+
+1. Download the artifact in your preferred format (either through GitHub's GUI or using the command line)  
+   `curl -L -O "https://github.com/StenAL/new-tab/releases/latest/download/new-tab.tar.gz"`
+2. Extract files from the archive (through a GUI like 7zip or using the command line)  
+   `tar -xvf new-tab.tar.gz`
+3. Set the TransferWise API token to your personal access token instead of the placeholder (either
+   open `build/static/js/main.RANDOM-LETTERS-AND-NUMBERS.js`, CTRL+F for "TOKEN-GOES-HERE" and replace it with your
+   token or use the command line)  
+   `sed -i 's/TOKEN-GOES-HERE/YOUR-ACTUAL-TOKEN/g' build/static/js/main.*.js`
+4. The page can now be accessed at `build/index.html`
+
+### Build locally
+
 1. Clone the git repository `git clone https://github.com/StenAL/favicon-marquee.git`
 2. Install dependencies using npm `npm i`

-4. Create a `.env` file at the root directory of your project and specify your
-   token in it `REACT_APP_TRANSFERWISE_API_TOKEN=token-goes-here`. This token
-   is only used for API calls and is never stored anywhere except your `.env` and `build` files
-5. Build the final static resources `npm run build`
