-        - Read the issue reporting section in the **[contributing guidelines](https://github.com/qbittorrent/qBittorrent/blob/master/CONTRIBUTING.md)**, to know how to submit a good bug report with the required information.
-        - Verify that the issue is not fixed and is reproducible in the **[latest official qBittorrent version](https://www.qbittorrent.org/download.php).**
-        - (Optional, but recommended) Verify that the issue is not fixed and is reproducible in the latest CI (**[macOS](https://github.com/qbittorrent/qBittorrent/actions/workflows/ci_macos.yaml?query=branch%3Amaster+event%3Apush)** / **[Ubuntu](https://github.com/qbittorrent/qBittorrent/actions/workflows/ci_ubuntu.yaml?query=branch%3Amaster+event%3Apush)** / **[Windows](https://github.com/qbittorrent/qBittorrent/actions/workflows/ci_windows.yaml?query=branch%3Amaster+event%3Apush)**) builds.
-        - Check the **[frequent/common issues list](https://github.com/qbittorrent/qBittorrent/projects/2)** and perform a **[search of the issue tracker (including closed ones)](https://github.com/qbittorrent/qBittorrent/issues)** to avoid posting a duplicate.
-        - Make sure this is not a support request or question, both of which are better suited for either the **[discussions section](https://github.com/qbittorrent/qBittorrent/discussions)**, **[forum](https://qbforums.shiki.hu/)**, or **[subreddit](https://www.reddit.com/r/qBittorrent/)**.
-        - Verify that the **[wiki](https://github.com/qbittorrent/qBittorrent/wiki)** did not contain a suitable solution either.

-*   Consult [coding guidelines][coding-guidelines-url] first. If you are working on translation/i18n, read ["How to translate qBittorrent"][how-to-translate-url].
-*   Keep your git commit history clean.
-    * Refer to the section about ["Git commit messages"][coding-guidelines-git-commit-message-url] in the coding guidelines.
-    * When merge conflicts arise, do `git rebase <target_branch_name>` and fix the conflicts, don't do `git pull`. Here is a good explanation: [merging-vs-rebasing][merging-vs-rebasing-url].
-*   Keep pull request title concise and provide motivation and "what it does" in the pull request description area. Make it easy to read and understand.
-*   Provide screenshots for UI related changes.
-*   If your commit addresses a reported issue (for example issue #8454), append the following text to the commit body `Closes #8454.`. Example [commit][commit-message-fix-issue-example-url].
-*   Search [pull request list][pull-request-list-url] first. Others might have already implemented your idea (or got rejected already).
+### Must read
+*   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.>

-    but WITHOUT ANY WARRANTY; without even the implied warranty of

-    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 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

+# SYNOPSIS
+#
+#   AX_BOOST_SYSTEM
+#
+# DESCRIPTION
+#
+#   Test for System library from the Boost C++ libraries. The macro requires
+#   a preceding call to AX_BOOST_BASE. Further documentation is available at
+#   <http://randspringer.de/boost/index.html>.
+#
+#   This macro calls:
+#
+#     AC_SUBST(BOOST_SYSTEM_LIB)
+#
+#   And sets:
+#
+#     HAVE_BOOST_SYSTEM
