-*   Read our [**coding guidelines**][coding-guidelines-url]. There are some scripts to help you: [uncrustify script][uncrustify-script-url], [astyle script][astyle-script-url], [(related thread)][coding-guidelines-thread-url].
-*   Keep the title **short** and provide a **clear** description about what your pull request does.
-*   Provide **screenshots** for UI related changes.
-*   Keep your git commit history **clean** and **precise.** Refer to the section about "Git commit messages" in the [**coding guidelines**][coding-guidelines-url].
-*   If your commit fixes a reported issue (for example #4134), add the following message to the commit `Closes #4134.`. Example [here][commit-message-fix-issue-example-url].

-### Good to know
-*   **Search** pull request history! Others might have already implemented your idea and it is waiting to be merged (or got rejected already). Save your precious time by doing a search first.
-*   When resolving merge conflicts, do `git rebase <target_branch_name>`, don't do `git pull`. Then you can start fixing the conflicts. Here is a good explanation: [link][merging-vs-rebasing-url].

+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+This General Public License does not permit incorporating your program into

+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
