+# What Settings Are Currently Available For Transient Units?
+
+Our intention is to make all settings that are available as unit file settings
+also available for transient units, through the D-Bus API. At the moment,
+device, swap, and target units are not supported at all as transient units, but
+others are pretty well supported.
+
+The lists below contain all settings currently available in unit files. The
+ones currently available in transient units are prefixed with `✓`.
+
+## Generic Unit Settings
+
+Most generic unit settings are available for transient units.
