-Building wimlib using Cygwin is not supported. I was trying this for a while,
-but I ran into some issues with mixing native Win32 functions and
-Cygwin-provided functions, so I just made it possible to do a native Win32 build
-instead.
+ * wimlib-imagex provides a better XPRESS ("fast") compression ratio than
+ Microsoft's ImageX.
+
+ * wimlib-imagex provides an easy-to-use "optimize" command to remove wasted
+ space from WIM files.
+
+ * In some cases, wimlib-imagex uses simpler command-line syntax. For
+ example, `wimlib-imagex capture' (or simply `wimcapture') defaults to
+ maximum compression by default, integrity tables are treated as persistent,
+ and in some cases image names need not be explicitly specified.
+
+ * Whenever possible, wimlib-imagex includes improved documentation and
+ informational output compared to Microsoft's software.
+
+ * On Windows, wimlib-imagex can correctly save and restore some combinations
+ of data that Microsoft's ImageX runs into bugs on --- for example,
+ uncompressed files in compressed directories, or files with alternate data
+ streams and multiple hard links.
+
+ * wimlib and wimlib-imagex are free software, so you can modify and/or audit
+ the source code.
+
+ ADDITIONAL NOTES
+
+Currently there is no graphical user interface available for wimlib or
+wimlib-imagex. It's recommended to use wimlib-imagex in scripts to avoid having
+to interactively enter commands. However, note that wimlib-imagex is largely
+just a command-line front-end for wimlib, and it's possible to use wimlib's API
+in other front-ends or applications.
