+#### Usage of Command Line Interface
+
+Command Line Interface (CLI) supports gzip-like arguments.
+By default CLI takes an input file and compresses it to an output file:
+```
+ Usage: lz4 [arg] [input] [output]
+```
+The full list of commands for CLI can be obtained with `-h` or `-H`. The ratio can
+be improved with commands from `-3` to `-16` but higher levels also have slower
+compression. CLI includes in-memory compression benchmark module with compression
+levels starting from `-b` and ending with `-e` with iteration time of `-i` seconds.
+CLI supports aggregation of parameters i.e. `-b1`, `-e18`, and `-i1` can be joined
+into `-b1e18i1`.
