 This plugin exposes the following global functions:
 
 ```javascript
-
+wpcaCookiesAreAllowed(); // returns whether all cookies are allowed
+wpcaAcceptCookies(); // trigger "accept all cookies"
+wpcaContentTypeIsAllowed(contentType); // returns whether the given content type is allowed
+wpcaAcceptContentType(contentType); // trigger "accept the given content type"
 ```
+
+Additionally, the event `wpcaCookiesAccepted` is triggered when all cookies are accepted,
+and `wpcaContentTypeAccepted` is triggered if a certain subset of cookies for one content type is accepted.
+
+### Gutenberg
+
+This plugin provides a Gutenberg block, called "External Content Wrapper",
+which blocks the child blocks from being rendered until sufficient cookie permissions are given.
+
+#### Usage Example
+
+1. Add the "External Content Wrapper" block to your post/page
+2. Select the content type (Analytics, Marketing, Social Media, etc.)
+3. Add your content blocks inside the wrapper
+4. The content will only be displayed after the user accepts the corresponding cookie type
+
+This is particularly useful for embedding content from external sources like YouTube videos, Google Maps, or social media feeds that may track user data.
