+# Grav YouTube Plugin
+
+`YouTube` is a simple [Grav][grav] Plugin that converts markdown links into responsive embeds.
+
+# Installation
+
+Installing the YouTube plugin can be done in one of two ways. Our GPM (Grav Package Manager) installation method enables you to quickly and easily install the plugin with a simple terminal command, while the manual method enables you to do so via a zip file.
+
+## GPM Installation (Preferred)
+
+The simplest way to install this plugin is via the [Grav Package Manager (GPM)](http://learn.getgrav.org/advanced/grav-gpm) through your system's Terminal (also called the command line).  From the root of your Grav install type:
+
+    bin/gpm install youtube
+
+This will install the YouTube plugin into your `/user/plugins` directory within Grav. Its files can be found under `/your/site/grav/user/plugins/youtube`.
+
+## Manual Installation
+
+To install this plugin, just download the zip version of this repository and unzip it under `/your/site/grav/user/plugins`. Then, rename the folder to `youtube`. You can find these files either on [GitHub](https://github.com/getgrav/grav-plugin-youtube) or via [GetGrav.org](http://getgrav.org/downloads/plugins#extras).
+
+You should now have all the plugin files under
+
+    /your/site/grav/user/plugins/youtube
+
+# Config Defaults
+
+```
+enabled: true
+built_in_css: true
+player_parameters:
+  autoplay: 0
+  cc_load_policy: 0
+  color: red
+  controls: 1
+  disablekb: 0
+  enablejsapi: 0
+  fs: 1
+  hl: ''
+  iv_load_policy: 1
+  loop: 0
+  modestbranding: 0
+  origin: ''
+  playsinline: 0
+  rel: 1
+  showinfo: 1
+  vq: default
+privacy_enhanced_mode: false
+```
+
+If you need to change any value, then the best process is to copy the [youtube.yaml](youtube.yaml) file into your `users/config/plugins/` folder (create it if it doesn't exist), and then modify there.  This will override the default settings.
+
+You can also set any of these settings on a per-page basis by adding them under a `youtube:` setting in your page header.  For example:
+
+    ---
+    title: YouTube Video
+    youtube:
+        player_parameters:
+            autoplay: 1
+    ---
+
+    [plugin:youtube](https://www.youtube.com/watch?v=BK8guP9ov2U)
+
+This will display a video and auto-play it.
+
+For more details on the `player_parameters`, please check out the [YouTube official documentation](https://developers.google.com/youtube/player_parameters)
+
+# Usage
+
+To use this plugin you simply need to include a youtube URL in markdown link such as:
+
+```
+[plugin:youtube](https://www.youtube.com/watch?v=BK8guP9ov2U)
+```
+
+Will be converted into the following embeded HTML:
+
+```
+<div class="grav-youtube"><iframe src="https://www.youtube.com/embed/BK8guP9ov2U" frameborder="0" allowfullscreen=""></iframe></div>
+```
+
+CSS is also loaded to provide the appropriate responsive layout.
+
+# Shortcode Syntax
+
+As of version `3.0` you can now use an alternative _shortcode_ syntax that supports passing in the player parameter values inline 
+
+```
+[youtube color=white autoplay=1]https://www.youtube.com/watch?v=BK8guP9ov2U[/youtube]
