+# This is an experimental feature, as the NIP has not been merged at the time of writing this.
+# NIP60/61 support so called nutzaps, or in other words, if a user carries their wallet on Nostr
+# They can use it to interact with DVMS. In this tutorial we will once again keep our simple example
+# But will focus on what needs to be done in order to make it work.
+
+
+# Important: In order to make this work you need to manually install the cashu library in your main environment.
+# Also see https://github.com/cashubtc/nutshell
+# Depending on your system you might need to install some further dependencies. Please see the readme in the above link.
