+# grunt-properties
+
+> Convert java .properties files to javascript
+
+## Getting Started
+This plugin requires Grunt `~0.4.1`
+
+If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to create a [Gruntfile](http://gruntjs.com/sample-gruntfile) as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
+
+```shell
+npm install grunt-properties --save-dev
+```
+
+Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
+
+```js
+grunt.loadNpmTasks('grunt-properties');
+```
+
+## The "properties" task
+
+### Overview
+In your project's Gruntfile, add a section named `properties` to the data object passed into `grunt.initConfig()`.
+
+```js
+grunt.initConfig({
+  properties: {
+    page_config: {
+      files: {
+        'tmp/page_config.js': ['test/fixtures/page_config.properties'],
+      },
+    },
+    page_color_config: {
+      options: {
+        namespace: 'mypage'
+      },
+      files: {
+        'tmp/page_color_config.js': ['test/fixtures/page_config.properties', 'test/fixtures/page_color_config.properties'],
+      },
+    },
+  },
+})
+```
+
+### Options
+
+#### options.namespace
+Type: `String`
+Default value: `'config'`
+
+Use a previously defined namespace.
+
+### Usage Examples
+
+#### Default namespace config
+```js
+grunt.initConfig({
+  properties: {
+    options: {},
+    files: {
+      'tmp/page_config.js': ['test/fixtures/page_config.properties'],
+    },
+  },
+})
+```
+
+#### Customized namespace
+```js
+grunt.initConfig({
+  properties: {
+    page_color_config: {
+      options: {
+        namespace: 'mypage'
+      },
+      files: {
+        'tmp/page_color_config.js': ['test/fixtures/page_config.properties', 'test/fixtures/page_color_config.properties'],
+      },
+    },
+  },
+})
+```
+
