 OpenSSL User Support resources
 ==============================
 
+_Under Construction; not more than a collection of text fragments yet._
+
+See the OpenSSL website www.openssl.org for details on how to obtain
+commercial technical support. Free community support is available through the
+openssl-users email list (see
+https://www.openssl.org/community/mailinglists.html for further details).
+
+If you have any problems with OpenSSL then please take the following steps
+first:
+
+ - Download the latest version from the repository
+   to see if the problem has already been addressed
+ - Configure with no-asm
+ - Remove compiler optimization flags
+
+If you wish to report a bug then please include the following information
+and create an issue on GitHub:
+
+ - OpenSSL version: output of 'openssl version -a'
+ - Configuration data: output of 'perl configdata.pm ==dump'
+ - OS Name, Version, Hardware platform
+ - Compiler Details (name, version)
+ - Application Details (name, version)
+ - Problem Description (steps that will reproduce the problem, if known)
+ - Stack Traceback (if the application dumps core)
+
+Just because something doesn't work the way you expect does not mean it
+is necessarily a bug in OpenSSL. Use the openssl-users email list for this type
+of query.

 For *questions* on how to use OpenSSL or what went wrong when you
 tried something, our primary resource is the mailing list

+
+
+You have general questions about using OpenSSL
+----------------------------------------------
+
+In this case the [openssl-users][] mailing list is the right place for you.
+The list is not only watched by the OpenSSL team members, but also by many
+other OpenSSL users. Here you will most likely get the answer to your questions.
+An overview over the [mailing lists](#mailing-lists) can be found below.
+
+You found a Bug
+---------------
+
+If you have any problems with OpenSSL then please take the following steps first:
+
+- Search the mailing lists and/or the GitHub issues to find out whether
+  the problem has already been reported.
+- Download the latest version from the repository to see if the problem
+  has already been addressed.
+- Configure without assembler support (`no-asm`) and check whether the
+  problem persists.
+- Remove compiler optimization flags.
+
+Please keep in mind: Just because something doesn't work the way you expect
+does not mean it is necessarily a bug in OpenSSL. If you are not sure,
+consider searching the mail archives and posting a question to the
+[openssl-users][] mailing list first.
+
+### Open an Issue
+
+If you wish to report a bug, please open an [issue][github-issues] on GitHub
+and include the following information:
+
+- OpenSSL version: output of `openssl version -a`
+- Configuration data: output of `perl configdata.pm --dump`
+- OS Name, Version, Hardware platform
+- Compiler Details (name, version)
+- Application Details (name, version)
+- Problem Description (steps that will reproduce the problem, if known)
+- Stack Traceback (if the application dumps core)
+
+Not only errors in the software, also errors in the documentation, in
+particular the manual pages, can be reported as issues.
+
+### Submit a Pull Request
+
+The fastest way to get a bug fixed is to fix it yourself ;-). If you are
+experienced in programming and know how to fix the bug, you can open a
+pull request. The details are covered in the [Contributing](#contributing) section.
+
+Don't hesitate to open a pull request, even if it's only a small change
+like a grammatical or typographical error in the documentation.
+

+
+Mailing Lists
+=============
+
+The OpenSSL maintains a number of [mailing lists][] for various purposes.
+The most important lists are:
+
+- [openssl-users][] for general questions about using the OpenSSL software
+                    and discussions between OpenSSL users.
+
+- [openssl-announce][] for official announcements to the OpenSSL community.
+
+- [openssl-project][]  for discussion about the development roadmap
+                       and governance.
+
+- [openssl-dev][]      for discussion about development of OpenSSL.
+
+The openssl-dev list has been discontinued since development is now taking
+place in form of GitHub pull requests. Although not active anymore, the
+searchable archive may still contain useful information.
