+Easily embed Spotify playlists, albums and tracks into your posts through the new Spotify Play Button.
+
+== Description ==
+
+Spotify Embed is based on the new [API by Spotify](https://developer.spotify.com/technologies/spotify-play-button/), better known as the Spotify Play Button.
+With Spotify Embed you can easily share your favored music tracks, albums and playlists with other Spotify users.
+
+= What's your part? =
+Just place a Spotify link into your posts. It can be a link to your favored track or album, but also music playlists are possible.
+**By default no shortcodes are necessary, just a link!**
+And that was about your part. Easy, isn't it?
+
+= What does the plugin? =
+The plugin will fetch your links of your music and will convert it to a sexy Spotify Play Button.
+
+= Some usage examples =
+To embed a simple Track just embed a link like this:
+`https://open.spotify.com/track/4IJUii1lg0IRLBs0yG1w2p`
+
+To embed an album just embed a link like this:
+`http://open.spotify.com/album/4pT0rlFvHYc46KyEhmCy88`
+
+Or to embed a complete playlist just embed a link like this:
+`http://open.spotify.com/user/sonymusic/playlist/1BVPSd4dynzdlIWehjvkPj`
+
+For more examples please vist the [FAQ section](http://wordpress.org/extend/plugins/spotify-embed/faq/).
+
+**Sounds pretty good? Install now!**
+
+= Coming soon =
+* Support for Spotify URLs like `spotify:album:4pT0rlFvHYc46KyEhmCy88`.
+
+
+*Spotify Embed is not associated in any way with Spotify by Spotify Ltd.*
+
+
+= Feedback = 
+If you want, you can drop me a line @[ocean90](http://twitter.com/ocean90) on Twitter or @[Dominik Schilling](https://plus.google.com/101675293278434581718/) on Google+.
+
+
+
+= More =
+If you want, you can try also some of my [other plugins](http://profiles.wordpress.org/users/ocean90) or visit my site [wpGrafie.de](http://wpgrafie.de/).
+
+
+
+
+== Frequently Asked Questions ==
+
+= Can I embed the light theme instead of the dark theme? =
+Yes, you can. Just wrap your link into the `[embed][/embed]` shortcode and add the keyword 'light'.
+Example:
+`[embed light]http://open.spotify.com/user/spotify/playlist/3Yrvm5lBgnhzTYTXx2l55x[/embed]`
+
+
+= I want to show the cover art, is that possible? =
+Yes. Just wrap your link into the `[embed][/embed]` shortcode and add the keyword 'coverart'.
+Example:
+`[embed coverart]http://open.spotify.com/user/spotify/playlist/3Yrvm5lBgnhzTYTXx2l55x[/embed]`
+
+
+= Where does the plugin get it's default height and width settings? =
+Therefor take a look at the Media settings under `Settings > Media > Embed`.
+
+
+= Can I customize the size of the embed box? =
+Yes. Just wrap your link into the `[embed][/embed]` shortcode and add the keywords 'height' and/or 'width'.
+(Note: Take also a look at the [Spotify documentation](https://developer.spotify.com/technologies/spotify-play-button/documentation/))
+Example:
+`[embed height="600" width="450"]http://open.spotify.com/user/spotify/playlist/3Yrvm5lBgnhzTYTXx2l55x[/embed]`
+
+Another option is the use of the `size` keyword. You can use `size="compact"` (80x250px) or `size="large"` (720x640px).
+Example:
+`[embed size="compact"]http://open.spotify.com/user/spotify/playlist/3Yrvm5lBgnhzTYTXx2l55x[/embed]`
+
+
+= Can I combine all these keywords? =
+Yes. (But don't try to combine the size keywords, or the sky will fall on your head)
+
+
+
+
+== Screenshots ==
+
+1. An example of an embed track.
+2. Here you can get the HTML link of your track, album or playlist, which you can insert into your content.
+
+
+
+
