 This README.md file exists for people browsing on github.
 
 The TeX-Live project on github (https://github.com/TeX-Live) is a mirror
 of the upstream Subversion repository (https://tug.org/texlive/svn). We
 use it primarily for automatic building of the sources on several platforms.
 
-We prefer using mailing lists to github: [email protected] for general
-bugs and discussion, [email protected] for bugs and patches for the compiled
-programs, and so on. List of TL lists: https://tug.org/texlive/lists.html.
+The releases built here (https://github.com/TeX-Live/texlive-source/releases)
+are not usable TeX systems on their own, but bare binary directories.
+They can be dropped into a TeX Live installation as some bin/newdir and
+they should work, including resolving the dangling symlinks that are in
+the bare tarballs.
+
+For reports and other feedback, we prefer using mailing lists:
+[email protected] for general bugs and discussion, [email protected] for bugs
+and patches for the compiled programs, and so on. All the TL mailing
+lists: https://tug.org/texlive/lists.html.
 
 However, if you prefer to open issues or submit PRs on github, that's
 ok. We will see them and will reply as soon as we can.

 maintainer, however they wish to receive reports, not to any general
 TeX Live list. TL redistributes what is uploaded to CTAN without changes.
