 AST
 ===
 
-This is the AT&T Software Technology ast software download site from AT&T Research.
-The AT&T AST OpenSource Software Collection provides an overview and Practical Reusable
-UNIX Software provides a historical perspective.
-You can join the ast and uwin mailgroups, or monitor the mail archives.
-There is also an AT&T internal talk.
-The man page index contains most of the ast commands and library functions;
-command man pages are also available at runtime using the --man or --html option of any ast command.
+This is the AT&T Software Technology (AST) toolkit from AT&T Research.
+It includes many tools and libraries, like KSH, NMAKE, SFIO, VMALLOC, VCODEX,
+etc. It also includes more efficient replacements for a lot of the POSIX tools.
+It was designed to be portable across many UNIX systems and also works
+under UWIN on Microsoft Windows (see UWIN repo on GitHub under att/uwin).
 
+This software is used to build itself, using NMAKE.
+After cloning this repo, cd to the top directory of it and run:
+
+./bin/package make
+
+Almost all the tools in this package (including the bin/package script are
+self-documenting; run <tool> --man (or --html) for the man page for the tool.
+
+(If you were used to the old AST packaging mechanism, on www.research.att.com,
+this repo is equivalent to downloading the INIT and ast-open packages and
+running: ./bin/package read on them).
