-A high compression derivative, called LZ4_HC, is also provided. 
-It trades CPU time for compression ratio.
+Speed can be tuned dynamically, selecting an "acceleration" factor

+-------------------------
 
 The raw LZ4 block compression format is detailed within [lz4_Block_format].
 
-Compressing an arbitrarily long file or data stream requires multiple blocks.
+To compress an arbitrarily long file or data stream, multiple blocks are required.
 Organizing these blocks and providing a common header format to handle their content
 is the purpose of the Frame format, defined into [lz4_Frame_format].
-Interoperable versions of LZ4 must respect this frame format too.
+Interoperable versions of LZ4 must respect this frame format.
+
+
+Other source versions
+-------------------------
+
+Beyond the C reference source, 
+many contributors have created versions of lz4 in multiple languages.
+A list of these sources is maintained on the [LZ4 Homepage].
