-4* API Changes !
+4* Contributing
 -_-_-_-_-_-_-_-_-_
 
-Changes between 0.4 and 0.5
----------------------------
-
-We use the ssh_ prefix as namespace for every function now. There is a legacy.h
-which could be used to get the old function names.
-
-Changes between 0.3 and 0.4
----------------------------
-
-We changed libssh to be typesafe now:
-
-SSH_SESSION *session -> ssh_session session
-SFTP_SESSION *sftp -> sftp_session sftp
-CHANNEL *channel -> ssh_channel channel
-STRING *string -> ssh_string string
-...
-
-The options structure has been removed and there is a new function. This
-function can set all available options now. You can find the enum in the
-header file and it is documented. Example:
-
-ssh_options_set(session, SSH_OPTIONS_HOST, "localhost");
-
-5* Copyright policy
--_-_-_-_-_-_-_-_-_-_
-
-libssh is a project with distributed copyright ownership, which means we prefer
-the copyright on parts of libssh to be held by individuals rather than
-corporations if possible. There are historical legal reasons for this, but one
-of the best ways to explain it is that it’s much easier to work with
-individuals who have ownership than corporate legal departments if we ever need
-to make reasonable compromises with people using and working with libssh.
-
-We track the ownership of every part of libssh via git, our source code control
-system, so we know the provenance of every piece of code that is committed to
-libssh.
-
-So if possible, if you’re doing libssh changes on behalf of a company who
-normally owns all the work you do please get them to assign personal copyright
-ownership of your changes to you as an individual, that makes things very easy
-for us to work with and avoids bringing corporate legal departments into the
-picture.
-
-If you can’t do this we can still accept patches from you owned by your
-employer under a standard employment contract with corporate copyright
-ownership. It just requires a simple set-up process first.
-
-We use a process very similar to the way things are done in the Linux Kernel
-community, so it should be very easy to get a sign off from your corporate
-legal department. The only changes we’ve made are to accommodate the license we
-use, which is LGPLv2 (or later) whereas the Linux kernel uses GPLv2.
-
-The process is called signing.
-
-How to sign your work
-----------------------
-
-Once you have permission to contribute to libssh from your employer, simply
-email a copy of the following text from your corporate email address to:
-
-contributing@libssh.org
-
---------------------------------------------------------------------------
-libssh Developer's Certificate of Origin. Version 1.0
-
-By making a contribution to this project, I certify that:
-
-(a) The contribution was created in whole or in part by me and I
-    have the right to submit it under the appropriate
-    version of the GNU General Public License; or
-
-(b) The contribution is based upon previous work that, to the best of
-    my knowledge, is covered under an appropriate open source license
-    and I have the right under that license to submit that work with
-    modifications, whether created in whole or in part by me, under
-    the GNU General Public License, in the appropriate version; or
-
-(c) The contribution was provided directly to me by some other
-    person who certified (a) or (b) and I have not modified it.
-
-(d) I understand and agree that this project and the contribution are
-    public and that a record of the contribution (including all
-    metadata and personal information I submit with it, including my
-    sign-off) is maintained indefinitely and may be redistributed
-    consistent with the libssh Team's policies and the requirements of
-    the GNU GPL where they are relevant.
-
-(e) I am granting this work to this project under the terms of the
-    GNU Lesser General Public License as published by the
-    Free Software Foundation; either version 2.1 of
-    the License, or (at the option of the project) any later version.

-
-We will maintain a copy of that email as a record that you have the rights to
-contribute code to libssh under the required licenses whilst working for the
-company where the email came from.
-
-Then when sending in a patch via the normal mechanisms described above, add a
-line that states:
-
-
-   Signed-off-by: Random J Developer <random@developer.example.org>
-
-
-using your real name and the email address you sent the original email you used
-to send the libssh Developer’s Certificate of Origin to us (sorry, no
-pseudonyms or anonymous contributions.)
-
-That’s it! Such code can then quite happily contain changes that have copyright
-messages such as:
-
-
-   (c) Example Corporation.
-
-
-and can be merged into the libssh codebase in the same way as patches from any
-other individual. You don’t need to send in a copy of the libssh Developer’s
-Certificate of Origin for each patch, or inside each patch. Just the sign-off
-message is all that is required once we’ve received the initial email.
+Please read the file 'SubmittingPatches' next to this README file. It explains
+our copyright policy and how you should send patches for upstream inclusion.
 
 Have fun and happy libssh hacking!
