+
 ## Options
 
+### options.brackets
+
+**Type**: `object|boolean`
+
+**Default**: `undefined`
+
+**Description**
+
+If enabled, split-string will not split inside brackets. The following brackets types are supported when `options.brackets` is `true`,
+
+```js
+{
+  '<': '>',
+  '(': ')',
+  '[': ']',
+  '{': '}'
+}
+```
+
+Or, if object of brackets must be passed, each property on the object must be a bracket type, where the property key is the opening delimiter and property value is the closing delimiter.
+
+**Examples**
+
+```js
+// no bracket support by default
+split('a.{b.c}');
+//=> [ 'a', '{b', 'c}' ]
+
+// support all basic bracket types: "<>{}[]()"
+split('a.{b.c}', {brackets: true});
+//=> [ 'a', '{b.c}' ]
+
+// also supports nested brackets 
+split('a.{b.{c.d}.e}.f', {brackets: true});
+//=> [ 'a', '{b.{c.d}.e}', 'f' ]

+// support only the specified brackets

+
+> Returns true if a value is a plain object, array or function.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-extendable
+```
+
+## Usage
+
+```js
+var isExtendable = require('is-extendable');
+```
+
+Returns true if the value is any of the following:
+
+* array
+* plain object
+* function
+
+## Notes
+
+All objects in JavaScript can have keys, but it's a pain to check for this, since we ether need to verify that the value is not `null` or `undefined` and:
+
+* the value is not a primitive, or
+* that the object is a plain object, function or array
+
+Also note that an `extendable` object is not the same as an [extensible object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/isExtensible), which is one that (in es6) is not sealed, frozen, or marked as non-extensible using `preventExtensions`.
+
+## Release history
+
+### v1.0.0 - 2017/07/20
+
+**Breaking changes**
+
+* No longer considers date, regex or error objects to be extendable
