 The IPFS core API provides all functionality that is not specific to setting up and starting or stopping a node. This API is available directly on an IPFS instance, on the command line (when using the CLI interface), and as an HTTP REST API. For a complete reference, see [![](https://img.shields.io/badge/interface--ipfs--core-API%20Docs-blue.svg)](https://github.com/ipfs/interface-ipfs-core).
 
-All the API methods aside from streaming methods (ones that end in `ReadableStream` or `PullStream`) are asynchronous and return Promises, but _also_ accept callbacks.

+##### Glob source
+
+A utility to allow files on the file system to be easily added to IPFS.
+
+###### `globSource(path, [options])`
+
+- `path`: A path to a single file or directory to glob from
+- `options`: Optional options
+- `options.recursive`: If `path` is a directory, use option `{ recursive: true }` to add the directory and all its sub-directories.
+- `options.ignore`: To exclude file globs from the directory, use option `{ ignore: ['ignore/this/folder/**', 'and/this/file'] }`.
+- `options.hidden`: Hidden/dot files (files or folders starting with a `.`, for example, `.git/`) are not included by default. To add them, use the option `{ hidden: true }`.
+
+Returns an async iterable that yields `{ path, content }` objects suitable for passing to `ipfs.add`.
+
+###### Example
+
+```js
+const IPFS = require('ipfs')
+const { globSource } = IPFS
+
+const ipfs = await IPFS.create()
+
+for await (const file of ipfs.add(globSource('./docs', { recursive: true }))) {
+  console.log(file)
+}
+
+/*

+  cid: CID('QmVHxRocoWgUChLEvfEyDuuD6qJ4PhdDL2dTLcpUy3dSC2'),

+}
+{
+  path: 'docs/assets/bass-addons.css',

+  size: 232
+}
+...

+
+##### URL source
+
+A utility to allow content from the internet to be easily added to IPFS.

+Returns an async iterable that yields `{ path, content }` objects suitable for passing to `ipfs.add`.

+
+```js
+const IPFS = require('ipfs')
+const { urlSource } = IPFS
+
+const ipfs = await IPFS.create()
+
+for await (const file of ipfs.add(urlSource('https://ipfs.io/images/ipfs-logo.svg'))) {
