+                data. It creates and maintains structured, indexed
+                journals based on logging information that is received
+                from the kernel, from user processes via the libc

+                call, from STDOUT/STDERR of system services or via its
+                native API. It will implicitly collect numerous meta
+                data fields for each log messages in a secure and
+                unfakeable way. See
+                <citerefentry><refentrytitle>systemd.journal-fields</refentrytitle><manvolnum>7</manvolnum></citerefentry>

+                text based but can also include binary data where
