+# Privacy Embed (Wordpress Plugin)
+
+This plugin adds some shortcodes to let you embed external content like youtube videos on your wordpress pages. Nothing new so far - why another plugin?
+
+Well, this plugin puts emphasis on data protection. Before the content is loaded from an external area of responsibility (a third-party provider), the user must explicitly agree to the data transfer. In this way, the site operator is supported in designing his website in a data protection-compliant manner (taking into account the GDPR, among other things).
+
+For the WPBakery Page Builder plugin, prefabricated blocks are also provided so that the shortcodes can be used directly.
+
+Currently, embeddings of the following services are supported:
+
+- YouTube videos (Google)
+- Spotify
+  - Artists
+  - Albums
+  - Tracks
+
+## installation & usage
+
+1. Make sure that your WordPress installation meets the minimum requirements of this plugin.
+2. Upload the plugin to the /wp-content/plugins/ directory or install it directly from the admin pages.
+3. Use the shortcodes:
+   - Spotify\*:  
+     `[privacy-embed_spotify title="Title of embed" spotify_url="spotify:album:1DFixLWuPkv3KT3TnV35m3"]`
+   - YouTube:  
+     `[privacy-embed_youtube title="Title of embed" youtube_link="https://www.youtube.com/watch?v=kV9sNmujCPk"]`
+
+\* You can get the Spotify URI by clicking \"Share\" on the Spotify page of any artist, album or track and then selecting \"Copy Spotify URI\".
+
