Documentation must be downloaded on a computer (PC, Mac, or Linux).
Do not use a smartphone or tablet to download documentation; they generally lack sufficient memory capacity to handle large files, and few users know how to locate the download folder on these devices.
Once downloaded, you can use it right away and even print the pages you need, or use your smartphone in photo mode to translate into the language of your choice: Google Translate
