+collectd can operate in four different operating modes. The modes are described

 The simplest mode is the so called B<local mode>. Data is collected locally and
 written in RRD files that reside in I<DataDir>. This is the default mode when
 collectd is linked against C<librrd>.
 
-The other two modes, B<client mode> and B<server mode>, are used to send data

+In B<client mode> the daemon collects the data locally and sends its results
+to one or more network addresses. No RRD files are written locally in this
+case. If collectd is not linked against C<librrd> this is the default mode.
 
 If started in B<server mode> the daemon will listen on one or more interfaces
 and write the data it receives to RRD files. No data is collected locally.
 
+In the last mode, B<log mode>, data is collected locally and written in
+text files that reside in I<DataDir>.
