+# TrueNAS deploy script for SCALE/CORE using websocket
+# It is recommend to use a wildcard certificate
+#
+# Websocket Documentation: https://www.truenas.com/docs/api/scale_websocket_api.html
+#
+# Tested with TrueNAS Scale - Electric Eel 24.10
+# Changes certificate in the following services:
+#  - Web UI
+#  - FTP
+#  - iX Apps
+#
+# The following environment variables must be set:
+# ------------------------------------------------
+#
+# # API KEY
+# # Use the folowing URL to create a new API token: <TRUENAS_HOSTNAME OR IP>/ui/apikeys
+# export DEPLOY_TRUENAS_APIKEY="<API_KEY_GENERATED_IN_THE_WEB_UI"
+#
