 A. How to update ICU
 
-1. Run "scripts/update.sh <version>" (e.g. 56-1).
+1. Run "scripts/update.sh <version>" (e.g. 58-1).
    This will download ICU from the upstream svn repository.
    It does preserve Chrome-specific build files (*local.mk) and
    converter files. (see section C)
 
 2. Update the source file lists for i18n and common
    in icu.gypi and BUILD.gn. See the comments in the files.
 
 3. Review and apply patches/changes in "D. Local Modifications" if
    necessary/applicable. Update patch files in patches/.
