+Repo API
+=======
+
+#### `gc`
+
+> Perform a garbage collection sweep on the repo.
+
+##### `Go` **WIP**
+
+##### `JavaScript` - ipfs.repo.gc([options, callback])
+
+Where:
+
+- `options` is an object that contains following properties
+  - `quiet` writes a minimal output.
+  - `stream-errors` stream errors.
+
+`callback` must follow `function (err, res) {}` signature, where `err` is an Error if the operation was not successful.
+
+If no `callback` is passed, a promise is returned.
+
+**Example:**
+
+```JavaScript
+ipfs.repo.gc((err, res) => console.log(res))
+```
+
+#### `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 }
+```
+
+#### `version`
+
+> Show the repo version.
+
+##### `Go` **WIP**
+
+##### `JavaScript` - ipfs.repo.version([callback])
+
+`callback` must follow `function (err, version) {}` signature, where `err` is an Error if the operation was not successful and `version` is a String containing the version.
+
+If no `callback` is passed, a promise is returned.
+
+**Example:**
+
+```JavaScript
+ipfs.repo.version((err, version) => console.log(version))
+
+// "6"
+```
