+
+Create new error instances with a code and additional properties.
+
+
+## Installation
+
+```console
+$ npm install err-code
+// or
+$ bower install err-code
+```
+
+The browser file is named index.umd.js which supports CommonJS, AMD and globals (errCode).
+
+
+## Why
+
+I find myself doing this repeatedly:
+
+```js
+var err = new Error('My message');
+err.code = 'SOMECODE';
+err.detail = 'Additional information about the error';
+throw err;
+```
+
+
+## Usage
+
+Simple usage.
+
+```js
+var errcode = require('err-code');
+
+// fill error with message + code
+throw errcode(new Error('My message'), 'ESOMECODE');
+// fill error with message + code + props
+throw errcode(new Error('My message'), 'ESOMECODE', { detail: 'Additional information about the error' });
+// fill error with message + props
+throw errcode(new Error('My message'), { detail: 'Additional information about the error' });
+```
+
+## Pre-existing fields
+
+If the passed `Error` already has a `.code` field, or fields specified in the third argument to `errcode` they will be overwritten, unless the fields are read only or otherwise throw during assignment in which case a new object will be created that shares a prototype chain with the original `Error`. The `.stack` and `.message` properties will be carried over from the original error and `.code` or any passed properties will be set on it.
+
+
+## Tests
+
+`$ npm test`
