+We recommend using the Pro plan of the [Simply Static](https://simplystatic.com/) plugin. When we started this plugin, it fixed the lack of a deployment feature in Simply Static. Since then, the plugin has been updated, and the Pro plan offers exactly what we were missing.  
+GRRR has contributed code and features to the Simply Static plugin, and we're happy to see it grow.  
+We suggest taking a look, it's well worth the investment.
+
+Thanks to everyone who has taken an interest in this plugin!  
+If you've enjoyed using this plugin or were inspired by it in any way, maybe you'd like to follow our blog, where we write about our work and the things we learn along the way: [grrr.tech](https://grrr.tech/).
