+# SETUP
+#
+# in config.php you'll need something like this:
+#
+# $GLOBALS['email_templates'] = [
+# 'slug' => [
+# 'title' => "Title shown in admin only",
+# 'description' => "explain (for admins) what this template is for",
+# 'variables' => [
+# ['name', "explan (for admins) what this variable is for"],
+# ['verbing', "admins can put these variables into the template"]
+# ],
+# 'subject' => "email subject",
+# 'content' => "Hi, ~name~ this is the email body, thanks for ~verbing~!",
+# 'from_addr' => 'noreply@airservices.info',
+# 'to_addr' => 'optional@to.address' # optional
+# ]
+# # , 'slug2' => ...
+# ];
+
+# To save results to a database, you'll need to create the email_templates table.
+# The file admin_email_templates.sql should help with this
+#
+# if you rename any of the database fields, you'll need to update this:
