+Examples:
+---------
 
 Suppose you'd like to create snapshots of the existing directory
 
-	/foo/bar
+		/foo/bar
 
 in the directory
 
-	/baz/qux.
+		/baz/qux.
 
 Create the config file
 
-	~/.dssrc
+		~/.dssrc
 
 that contains the values for the source and the destination directories
 as follows:
 
-	echo 'source-dir "/foo/bar"' > ~/.dssrc
-	echo 'dest-dir "/baz/qux"' >> ~/.dssrc
+		echo 'source-dir "/foo/bar"' > ~/.dssrc
+		echo 'dest-dir "/baz/qux"' >> ~/.dssrc
 
 Then execute the commands
 
-	mkdir /baz/qux
-	dss --run
+		mkdir /baz/qux
+		dss run
 
 In order to print the list of all snapshots created so far, use
 
-	dss --list
+		dss ls
+
+Yes, it's really that easy.
+
+The second example involves a slightly more sophisticated config file.
+It instructs dss to exclude everything which matches at least one
+pattern of the given exclude file, prevents rsync from crossing file
+system boundaries and increases the number of snapshots.
+
+		source-dir "/foo/bar"
+		dest-dir "/baz/qux"
+		# exclude files matching patterns in /etc/dss.exclude
+		rsync-option "--exclude-from=/etc/dss.exclude"
+		# don't cross filesystem boundaries
+		rsync-option "--one-file-system"
+		# maintain 2^6 - 1 = 63 snaphots
+		num-intervals "6"
+
+The /etc/dss.exclude file could look like this (see rsync(1) for
+more examples)
+
+
+		 - /proc
+		 - /**/tmp/
