+# After opening a Wireguard connection to your Fly network, run this script to

+
+# In order for it to work:
+# - Your wireguard connection must be up.
+# - The COOKIE value must be the same as the cookie value used for your project.
+# - Observer needs to be working in your local environment. That requires WxWidget support in your Erlang install.
+
+# When done, close Observer. It leaves you with an open IEx shell that is connected to the remote server. You can safely CTRL+C, CTRL+C to exit it.

+# ============

+#
+# COOKIE=YOUR-COOKIE-VALUE

+# here. Choose the version that fits your situation.
