 You will need to replace `<xxx@xxx.xxx>` and `<password>` with your Packt account email and password, respectively. Additionally, you can customize the output formats of the downloaded books by modifying the `PACKT_DOWNLOAD_FORMATS` environment variable. The default formats are `pdf`, `epub`, `mobi`, and `code`.
 
-To automatically solve the CAPTCHA, you will need an AntiCaptcha API key, which you can set by attaching the `-e PACKT_ANTICAPTCHA_KEY=<key>` flag to your docker run command.
+To automatically solve the CAPTCHA, you will need an [AntiCaptcha](https://anti-captcha.com/) API key, which you can set by attaching the `-e PACKT_ANTICAPTCHA_KEY=<key>` flag to your docker run command.
 
 You can mount two volumes to persist the Packt credentials and store the downloaded books in a directory on your host system. The `/config` directory will store your Packt credentials, and the `/data` directory will store the downloaded books. You can change the paths of the host directories by modifying the values after the `-v` flag.
 
 Once you run the container, it will automatically download a free eBook each day from Packt publishing and store the files in the `/home/user/packt/books` directory on your host system.
 
+If you would prefer to use an alternative to ghcr.io, you can use the image hosted on [Docker Hub](https://hub.docker.com/repository/docker/ghostwriters/docker-packt-cli) `ghostwriters/docker-packt-cli:latest`,
