+
+A mailing list where users may help each other exists, and you can
+reach it by sending e-mail to @email{gnutls-help@@gnutls.org}.  Archives
+of the mailing list discussions, and an interface to manage
+subscriptions, is available through the World Wide Web at
+@url{https://lists.gnutls.org/pipermail/gnutls-help/}.
+
+A mailing list for developers are also available, see
+@url{https://www.gnutls.org/lists.html}.
+Bug reports should be sent to @email{bugs@@gnutls.org}, see
+@ref{Bug Reports}.
+
+@node Commercial Support
+@section Commercial Support
+
+Commercial support is available for users of GnuTLS. See
+@url{https://www.gnutls.org/commercial.html} for more information.

+@node Bug Reports
+@section Bug Reports
+@cindex reporting bugs
+
+If you think you have found a bug in GnuTLS, please investigate it and
+report it.
+
+@itemize @bullet
+
+@item Please make sure that the bug is really in GnuTLS, and
+preferably also check that it hasn't already been fixed in the latest
+version.
+
+@item You have to send us a test case that makes it possible for us to
+reproduce the bug.
+
+@item You also have to explain what is wrong; if you get a crash, or
+if the results printed are not good and in that case, in what way.
+Make sure that the bug report includes all information you would need
+to fix this kind of bug for someone else.
+
+@end itemize
+
+Please make an effort to produce a self-contained report, with
+something definite that can be tested or debugged.  Vague queries or
+piecemeal messages are difficult to act on and don't help the
+development effort.
+
+If your bug report is good, we will do our best to help you to get a
+corrected version of the software; if the bug report is poor, we won't
+do anything about it (apart from asking you to send better bug
+reports).
+
+If you think something in this manual is unclear, or downright
+incorrect, or if the language needs to be improved, please also send a
+note.
+
+Send your bug report to:
+
+@center @samp{bugs@@gnutls.org}

+@cindex contributing
+@cindex hacking
+
+If you want to submit a patch for inclusion -- from solving a typo you
+discovered, up to adding support for a new feature -- you should
+submit it as a bug report, using the process in @ref{Bug Reports}.  There are some
+things that you can do to increase the chances for it to be included
+in the official package.
+
+Unless your patch is very small (say, under 10 lines) we require that
+you assign the copyright of your work to the Free Software Foundation.
+This is to protect the freedom of the project.  If you have not
+already signed papers, we will send you the necessary information when
+you submit your contribution.
+
+For contributions that doesn't consist of actual programming code, the
+only guidelines are common sense.  
+For code contributions, a number of style guides will help you:
+
+@itemize @bullet
+
+@item Coding Style.
+Follow the GNU Standards document.
+@c (@pxref{top, GNU Coding Standards,,standards}).
+
+If you normally code using another coding standard, there is no
+problem, but you should use @samp{indent} to reformat the code
+@c (@pxref{top, GNU Indent,, indent}) 
+before submitting your work.
+
+@item Use the unified diff format @samp{diff -u}.
+
+@item Return errors.
+No reason whatsoever should abort the execution of the library.  Even
+memory allocation errors, e.g. when malloc return NULL, should work
+although result in an error code.
+
+@item Design with thread safety in mind.
+Don't use global variables.  Don't even write to per-handle global
+variables unless the documented behaviour of the function you write is
+to write to the per-handle global variable.
+
+@item Avoid using the C math library.
+It causes problems for embedded implementations, and in most
+situations it is very easy to avoid using it.
+
+@item Document your functions.
+Use comments before each function headers, that, if properly
+formatted, are extracted into Texinfo manuals and GTK-DOC web pages.
+
+@item Supply a ChangeLog and NEWS entries, where appropriate.

+@node Certification
+@section Certification
+@cindex certification
+
+There are certifications from national or international bodies which "prove"
+to an auditor that the crypto component follows some best practices, such
+as unit testing and reliance on well known crypto primitives.
+
+GnuTLS has support for the FIPS 140-2 certification under Red Hat Enterprise Linux.
+See @ref{FIPS140-2 mode} for more information.
