Once uploaded, the hash of **the manifest** is returned. Accessing the manifest from `bzz:/` will not return anything. Instead, you can use the hash as the root of your directory and access the individual files by appending them to the end of the URL. So, if we uploaded a directory containing `index.html`, we will be able to access it via `<gateway url>/bzz:/<hash>/index.html`. Once uploaded, the hash of **the manifest** is returned. Accessing the manifest from `bzz:/` will 404. Instead, you can use the hash as the root of your directory and access the individual files by appending them to the end of the URI, then call `swarmapi download <uri>`.
