Sneakerweb is a peer-to-peer protocol designed for permissionless web publishing, operating entirely without DNS servers, domain registrars, or traditional web hosts.

Here are the main features and the workflow for setting up your site once it is finished:

Main Features

• Physical Media Transport: Instead of using the central internet, websites are transferred between users via physical storage media (like USB drives) using .snk files.

• Censorship Resistance: By removing the need for a central infrastructure, it serves as an "ultimate fallback" for web publishing.

How to Install and Publish Your Site

Once you have finished your static website, follow these steps to get it running on the network:

1. Installation: Download the sneakerweb CLI from the official downloads page.

2. Claim a Domain: Use the command sneakerweb domain to claim a unique sneakerweb domain for your project.

3. Publish Your Content: Use the command sneakerweb publish to link your finished static website files to your claimed domain.

4. Verify Locally: Run sneakerweb serve to start a local server, allowing you to browse your collection and see your site in your web browser.

5. Share with Others: Use sneakerweb export to turn your site into a .snk file, which you can then give to others via physical media. They can then use sneakerweb import to add it to their own collection.
