+## Well, okey... Then how does tauri-plugin-holochain help me now?
+
+For now, you can build a desktop only executable hApp that your users can download and use. It's ready to be deployed and iterated upon. After the issues with holochain mobile outlined above are resolved, you will be able to upgrade to a new version of the plugin to automatically get mobile support in your hApp.
+
+This is the way ourselves in darskoil studio are building hApps right now. We are monitoring the issues at the technical level, and in constant communication with the core holochain development team. At the same time, while they get resolved, we are building the MVP version for our hApps.
