    Enough with the marketing. Here's how Syncany looks like in the wild.

    Create: Creating a new repository is a matter of seconds with the sy init command. We use the FTP plugin here.
    Connect: Other clients can connect to the repository and sync files manually with sy up and sy down.
    Automatic sync: Using the sy watch command, clients can automatically sync their files.

    Still no idea what we're talking about?
