+    <title>Description</title>
+
+    <para><command>systemd-coredump</command> can be used as a helper
+    binary by the kernel when a user space program receives a fatal
+    signal and dumps core. For it to be used in this capacity, it must
+    be specified by the
+    <varname>kernel.core_pattern</varname> <citerefentry project='man-pages'><refentrytitle>sysctl</refentrytitle><manvolnum>8</manvolnum></citerefentry>
+    setting. Systemd installs
+    <filename>/usr/lib/sysctl.d/50-coredump.conf</filename> which
+    configures <varname>kernel.core_pattern</varname> to invoke
+    <command>systemd-coredump</command>. This file may be masked or
+    overriden to use a different setting following normal
+    <citerefentry><refentrytitle>sysctl.d</refentrytitle><manvolnum>5</manvolnum></citerefentry> rules.</para>
+
+    <para>The behaviour of a specific program upon reception of a
+    signal is governed by a few factors which are described in detail
+    in <citerefentry project='man-pages'><refentrytitle>core</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
+    In particular, the coredump will only be processed when the
+    related resource limits are high enough. For programs started by
+    <command>systemd</command> those may be set using
+    <varname>LimitCore=</varname> (see
+    <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>).
+    </para>
+
+    <para><command>systemd-coredump</command> will log the coredump
+    including a backtrace if possible, and store the core (contents of
+    process' memory contents) in an external file on disk in
+    <filename>/var/lib/systemd/coredump</filename>, or directly in
+    the journal. This behaviour may be modified using
+    <citerefentry><refentrytitle>coredump.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para>
+
+    <para>Apart from the
+    <citerefentry><refentrytitle>journalctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+    log viewer,
+    <citerefentry><refentrytitle>coredumpctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+    may be used to list and extract coredumps.</para>
