+# `browser-env-register`
+
+> Simplified browser testing in your node test suite.
+
+# Motivation
+
+`browser-env-register` lets you register a simulated browser environment using [browser-env], saving the hassle of creating and loading a test-helper file.
+
+# Features
+
++ ✅ **Compatible.** Works with [ava], [mocha] and everything else.
++ ✅ **Configurable.** via `package.json` or `browser-env.{js, json, yaml}`
++ ✅ **Reliable.** 100% Code Coverage.
++ ✅ **Free.** MIT License.
+
+# Usage
+
+## Install
+
+```sh
+npm add -D browser-env-register
+```
+
+### ava
+
+```js
+// package.json
+
+{
+  "ava": {
+    require: [
+      "browser-env-register"
+    ]
+  }
+}
+```
+
+### mocha
+
+```js
+# mocha.opts
+--require browser-env-register
+```
+
+## Configuration (optional)
+
+`browser-env-register` runs out of the box without further configuration, but you can set options if needed in your `package.json` or a  `browser-env.{js,json,yaml}` config file.
+
+#### package.json
+
+```
+{
+  "browser-env": {
+    "globals": ['window', 'document'],
+    "jsdom": {
+      userAgent: 'My User Agent'
+    }
+  }
+}
+```
+
+
+#### Shortcuts
+
+Pass only the of name global properties without setting jsdom options:
+
+```
+{
+  "browser-env": "window document"
+}
+```
+
+```
+{
+  "browser-env": ["window", "document"]
+}
+```
+
+Pass only jsdom options without setting the of name global properties:
+
+```
+{
+  "browser-env": {
+    "userAgent": "My User Agent"
+  }
+}
+```
