+Stats API
+=======
+
+#### `bitswap`
+
+> Adds an IPFS object to the pinset and also stores it to the IPFS repo. pinset is the set of hashes currently pinned (not gc'able).
+
+##### `Go` **WIP**
+
+##### `JavaScript` - ipfs.stats.bitswap([callback])
+
+`callback` must follow `function (err, stats) {}` signature, where `err` is an error if the operation was not successful. `stats` is an Object containing the following keys:
+
+- `provideBufLen`
+- `wantlist` (array)
+- `peers` (array)
+- `blocksReceived`
+- `dataReceived`
+- `blocksSent`
+- `dataSent`
+- `dupBlksReceived`
+- `dupDataReceived`
+
+If no `callback` is passed, a promise is returned.
+
+**Example:**
+
+```JavaScript
+ipfs.stats.bitswap((err, stats) => console.log(stats))
+
+// { provideBufLen: 0,
+//   wantlist: null,
+//   peers:
+//    [ 'QmSoLPppuBtQSGwKDZT2M73ULpjvfd3aZ6ha4oFGL1KrGM',
+//      'QmSoLSafTMBsPKadTEgaXctDQVcqN88CNLHXMkTNwMKPnu',
+//      'QmSoLer265NRgSp2LA3dPaeykiS1J6DifTC88f5uVQKNAd' ],
+//   blocksReceived: 0,
+//   dataReceived: 0,
+//   blocksSent: 0,
+//   dataSent: 0,
+//   dupBlksReceived: 0,
+//  dupDataReceived: 0 }
+```
+
+#### `bw`
+
+> Adds an IPFS object to the pinset and also stores it to the IPFS repo. pinset is the set of hashes currently pinned (not gc'able).
+
+##### `Go` **WIP**
+
+##### `JavaScript` - ipfs.stats.bw([options, callback])
+
+Where:
+
+- `options` is an opcional object that might contain the following keys:
+  - `peer` specifies a peer to print bandwidth for.
+  - `proto` specifies a protocol to print bandwidth for.
+  - `poll` is used to print bandwidth at an interval.
+  - `interval` is the time interval to wait between updating output, if `poll` is true.
+
+`callback` must follow `function (err, stats) {}` signature, where `err` is an error if the operation was not successful. `stats` is an Object containing the following keys:
+
+- `totalIn`
+- `totalOut`
+- `rateIn`
+- `rateOut`
+
+If no `callback` is passed, a promise is returned.
+
+**Example:**
+
+```JavaScript
+ipfs.stats.bw((err, stats) => console.log(stats))
+
+// { totalIn: 15456,
+//   totalOut: 15420,
+//   rateIn: 905.0873512246716,
+//   rateOut: 893.7400053359125 }
+```
+
+#### `stat`
+
+> Get stats for the currently used repo.
+
+##### `Go` **WIP**
+
+##### `JavaScript` - ipfs.repo.stat([options, callback])
+
+Where:
+
+- `options` is an object that contains following properties
+  - `human` a Boolean value to output `repoSize` in MiB.
+
+`callback` must follow `function (err, stats) {}` signature, where `err` is an Error if the operation was not successful and `stats` is an object containing the following keys:
+
+- `numObjects`
+- `repoSize`
+- `repoPath`
+- `version`
+- `storageMax`
+
+If no `callback` is passed, a promise is returned.
+
+**Example:**
+
+```JavaScript
+ipfs.repo.stat((err, stats) => console.log(stats))
+
+// { numObjects: 15,
+//   repoSize: 64190,
+//   repoPath: 'C:\\Users\\henri\\AppData\\Local\\Temp\\ipfs_687c6eb3da07d3b16fe3c63ce17560e9',
+//   version: 'fs-repo@6',
+//   storageMax: 10000000000 }
+```
