+#### <i class="fas fa-bug"></i> Report a bug
+
+GNU Octave uses the bug tracker at [GNU Savannah]({{ site.bugs_url }}).
+There you can
+[<i class="far fa-plus-square"></i> report a new bug](https://savannah.gnu.org/bugs/?group=octave&func=additem),
+[<i class="far fa-list-alt"></i> browse recent bugs]({{ site.bugs_url }}),
+or [<i class="fas fa-search"></i> search for bugs](https://savannah.gnu.org/bugs/?group=octave&func=search).
+
+<a href="{{ "/img/savannah_bug_report.png" | relative_url }}">

+
+1. **Is the bug already known?**
+
+   [<i class="fas fa-search"></i> Search for already reported bugs](https://savannah.gnu.org/bugs/?group=octave&func=search)
+   at the bug tracker first.
+   If you your problem **does not appear** to be known,
+   then you should report the problem.
+
+2. **Is it really a bug?**
+
+   - If Octave **crashes**, for any input whatever, that is a bug.
+     Reliable interpreters never crash.
+   - If Octave produces **incorrect results**, for any input whatever,
+     that is a bug.
+   - If Octave produces an **error message** for **valid input**, that is a bug.
+   - If Octave produces **no error message** for **invalid input**,
+     that is a bug.
+
+   <p></p>
+
+3. **Missing function in Octave**
+
+   If a function exists in Matlab, but not in Octave, this is **not** a bug.
+
+   - The function might already be
+     [part of an Octave package]({{ site.sourceforge_url }}/functions_by_alpha.php).
+   - You may file a **feature request** for it on the bug tracker.
+
+   <p></p>
+
+   Please be aware that it might take **several months**
+   until for new features become part of Octave.
+   Consider [<i class="fas fa-comment-dollar"></i> commercial support]({{ "commercial-support.html" | relative_url }})
+   if you don't want to wait that long.
+
+4. **Make your bug report count**
+
+   - **Report all the facts:**<br>
+     Include all information that make it possible to fix the bug.
+     If you are not sure whether to state a fact or leave it out, state it.
+     This information includes your **operating system**, **Octave version**,
+     **exact error message** or **exact output**.
+   - **Give a short, specific, complete example:**<br>
+     Avoid: pseudocode, uninitialized variables,
+     calls to unattached scripts or functions.
+   - **Justify your expectations briefly:**<br>
+     Although it might seem obvious to you,
+     someone examining the problem might not know what result you consider
+     correct.
+
+
+#### Sending Patches for Octave
+
+If you have a suggested fix for a bug,
+please attach it to your report in the tracker.
+Your patch is more likely to be reviewed if you follow the guidelines from the
+Octave Wiki about the [creation of changesets]({{ site.wiki_url }}/Mercurial).
