How to use the App: To download the sites locally, you can proceed in two ways: 1. Save the site(s) in .zip format in a repository that doesn't require authentication and edit a json file pointing to the site URLs like this:

[ { "id": "UniqueID", "name": "the name of the presetation", "version": "1.0", "zipUrl": "https://URL_TO_THE_ZIP_FILE", "thumbnail": "https://URL_TO_THE_THUMBANIL(optional)", "fileSize": 5488344, "updatedAt": "2026-04-14" } ]

Save the Json in a free repository too, then enter the URL to the JSON file in the app settings. Using a Json file with correct id and version let you manage the update of the same site.

Share the .zip file via email using the form found here: https://areatestrepository.github.io/html5catalogs/link-generator.html. Once generated the link you can edit and modify the message and copy and paste it in your preferred mail client.
