-See [\ref{ref_JFFSdwmw2}] for more details about GC in JFFS2. It is almost the
-same in JFFS3. 
+The Garbage Collector is very important part of JFFS3 subsystem which performs
+several tasks. The main task of the GC is reclaiming the dirty space - it moves
+all the valid nodes from dirty eblocks, thus reclaiming the space occupire by
+the dirt. Another tasks done by the GC are wear-levelling and producing pristing
+nodes.
+
+See [\ref{ref_JFFSdwmw2}] for more details about GC in JFFS2 which is pretty close
+to the GC in JFFS3.
