IPFS is a peer-to-peer protocol to share and access content-addressed data.
Everything in IPFS is addressed by an IPFS-path like:
/(ipfs|ipns)/<content_identifier>/path/to/thing
The content identifier (CID) can be obtained by adding files or folders to your IPFS daemon with "ipfs add".

It works similar to the HTTP gateway. You can provide IPFS and IPNS paths as follows:
