-The above LZX data are using explicitly specified maximum compression
-('--compress=maximum') as of wimlib v1.5.3. If `wimlib-imagex capture' or
-`wimlib-imagex capture' is instead run with no '--compress' argument, then a
-faster LZX compressor is used; it will produce results in between those given
-for XPRESS and LZX above.

-Note: if the absolute maximum but still compatible (i.e. not changing the
-compression chunk size) LZX compression ratio is desired, `wimlib-imagex
-optimize WIMFILE --recompress --compress-slow' on one of the above
-LZX-compressed WIMs produces a WIM of 187,089,943 bytes in about 400 seconds.
+wimlib (and wimlib-imagex) can create XPRESS, LZX, and LZMS compressed WIM
+archives. wimlib's compression codecs usually outperform and outcompress their
+closed-source Microsoft equivalents. Multiple compression levels and chunk
+sizes as well as solid mode compression are supported. Compression is
+multithreaded by default. Detailed benchmark results and descriptions of the
+algorithms used can be found at https://wimlib.net/compression.html.
