+                  IPFS -- Inter-Planetary File system
+
+IPFS is a global, versioned, peer-to-peer filesystem. It combines good ideas
+from Git, BitTorrent, Kademlia, SFS, and the Web. It is like a single bit-
+torrent swarm, exchanging git objects. IPFS provides an interface as simple
+as the HTTP web, but with permanence built in. You can also mount the world
+at /ipfs.
+
+IPFS is a protocol:
+- defines a content-addressed file system
+- coordinates content delivery
+- combines Kademlia + BitTorrent + Git
+
+IPFS is a filesystem:
+- has directories and files
+- mountable filesystem (via FUSE)
+
+IPFS is a web:
+- can be used to view documents like the web
+- files accessible via HTTP at `http://ipfs.io/<path>`
+- browsers or extensions can learn to use `ipfs://` directly
+- hash-addressed content guarantees authenticity
+
+IPFS is modular:
+- connection layer over any network protocol
+- routing layer
+- uses a routing layer DHT (kademlia/coral)
+- uses a path-based naming service
+- uses bittorrent-inspired block exchange
+
+IPFS uses crypto:
+- cryptographic-hash content addressing
+- block-level deduplication
+- file integrity + versioning
+- filesystem-level encryption + signing support
+
+IPFS is p2p:
+- worldwide peer-to-peer file transfers
+- completely decentralized architecture
+- **no** central point of failure
+
+IPFS is a cdn:
+- add a file to the filesystem locally, and it's now available to the world
+- caching-friendly (content-hash naming)
+- bittorrent-based bandwidth distribution
+
+IPFS has a name service:
+- IPNS, an SFS inspired name system
+- global namespace based on PKI
+- serves to build trust chains
+- compatible with other NSes
+- can map DNS, .onion, .bit, etc to IPNS

# 0.1 - Quick Start
+
+This is a set of short examples with minimal explanation. It is meant as
+a "quick start". Soon, we'll write a longer tour :-)
+
+
+Add a file to ipfs:
+
+  echo "hello world" >hello
+  ipfs add hello
+
+
+View it:
+
+  ipfs cat <the-hash-you-got-here>
+
+
+Try a directory:
+
+  mkdir foo
+  mkdir foo/bar
+  echo "baz" > foo/baz
+  echo "baz" > foo/bar/baz
+  ipfs add -r foo
+
+
+View things:
+
+  ipfs ls <the-hash-here>
+  ipfs ls <the-hash-here>/bar
+  ipfs cat <the-hash-here>/baz
+  ipfs cat <the-hash-here>/bar/baz
+  ipfs cat <the-hash-here>/bar
+  ipfs ls <the-hash-here>/baz
+
+
+References:
+
+  ipfs refs <the-hash-here>
+  ipfs refs -r <the-hash-here>

+  diff foo foo2
+
+
+Objects:
+
+  ipfs object get <the-hash-here>
+  ipfs object get <the-hash-here>/foo2

+’	Š	                    IPFS Alpha Security Notes
+
+We try hard to ensure our system is safe and robust, but all software
+has bugs, especially new software. This distribution is meant to be an
+alpha preview, don't use it for anything mission critical.
+
+Please note the following:
+
+- This is alpha software and has not been audited. It is our goal
+  to conduct a proper security audit once we close in on a 1.0 release.
+
+- ipfs is a networked program, and may have serious undiscovered
+  vulnerabilities. It is written in Go, and we do not execute any
+  user provided data. But please point any problems out to us in a
+  github issue, or email security@ipfs.io privately.
+
+- security@ipfs.io GPG key:
+  - 4B9665FB 92636D17 7C7A86D3 50AAE8A9 59B13AF3
+  - https://pgp.mit.edu/pks/lookup?op=get&search=0x50AAE8A959B13AF3
+
+- ipfs uses encryption for all communication, but it's NOT PROVEN SECURE
+  YET!  It may be totally broken. For now, the code is included to make
+  sure we benchmark our operations with encryption in mind. In the future,
+  there will be an "unsafe" mode for high performance intranet apps.
+  If this is a blocking feature for you, please contact us.

+This is a repository of IPLD objects. Each IPLD object is in a single file,
+named <base32 encoding of cid>.data. Where <base32 encoding of cid> is the
+"base32" encoding of the CID (as specified in
+https://github.com/multiformats/multibase) without the 'B' prefix.
+All the object files are placed in a tree of directories, based on a
+function of the CID. This is a form of sharding similar to
+the objects directory in git repositories. Previously, we used
+prefixes, we now use the next-to-last two charters.
+    func NextToLast(base32cid string) {
+      nextToLastLen := 2
+      offset := len(base32cid) - nextToLastLen - 1
+      return str[offset : offset+nextToLastLen]
+    }
+For example, an object with a base58 CIDv1 of
+    zb2rhYSxw4ZjuzgCnWSt19Q94ERaeFhu9uSqRgjSdx9bsgM6f
+has a base32 CIDv1 of
+    BAFKREIA22FLID5AJ2KU7URG47MDLROZIH6YF2KALU2PWEFPVI37YLKRSCA
+and will be placed at
+    SC/AFKREIA22FLID5AJ2KU7URG47MDLROZIH6YF2KALU2PWEFPVI37YLKRSCA.data
+with 'SC' being the last-to-next two characters and the 'B' at the
+beginning of the CIDv1 string is the multibase prefix that is not
+stored in the filename.
