+<p>CodeIgniter is a community driven project and accepts contributions of code
+and documentation from the community. These contributions are made in the form
+of Issues or <a class="reference external" href="https://help.github.com/articles/using-pull-requests/">Pull Requests</a>
+on the <a class="reference external" href="https://github.com/bcit-ci/CodeIgniter">CodeIgniter repository</a> on GitHub.</p>
+<p>Issues are a quick way to point out a bug. If you find a bug or documentation
+error in CodeIgniter then please check a few things first:</p>
+<ul class="simple">
+<li>There is not already an open Issue</li>
+<li>The issue has already been fixed (check the develop branch, or look for
+closed Issues)</li>
+<li>Is it something really obvious that you fix it yourself?</li>
+</ul>
+<p>Reporting issues is helpful but an even better approach is to send a Pull
+Request, which is done by &#8220;Forking&#8221; the main repository and committing to your
+own copy. This will require you to use the version control system called Git.</p>
+<div class="section" id="support">
+<h2>Support<a class="headerlink" href="#support" title="Permalink to this headline">¶</a></h2>
+<p>Please note that GitHub is not for general support questions! If you are
+having trouble using a feature of CodeIgniter, ask for help on our
+<a class="reference external" href="http://forum.codeigniter.com/">forums</a> instead.</p>
+<p>If you are not sure whether you are using something correctly or if you
+have found a bug, again - please ask on the forums first.</p>
+</div>
+<div class="section" id="security">
+<h2>Security<a class="headerlink" href="#security" title="Permalink to this headline">¶</a></h2>
+<p>Did you find a security issue in CodeIgniter?</p>
+<p>Please <em>don&#8217;t</em> disclose it publicly, but e-mail us at <a class="reference external" href="mailto:security&#37;&#52;&#48;codeigniter&#46;com">security<span>&#64;</span>codeigniter<span>&#46;</span>com</a>,
+or report it via our page on <a class="reference external" href="https://hackerone.com/codeigniter">HackerOne</a>.</p>
+<p>If you&#8217;ve found a critical vulnerability, we&#8217;d be happy to credit you in our
+<cite>ChangeLog &lt;../changelog&gt;</cite>.</p>
+</div>
+<div class="section" id="tips-for-a-good-issue-report">
+<h2>Tips for a Good Issue Report<a class="headerlink" href="#tips-for-a-good-issue-report" title="Permalink to this headline">¶</a></h2>
+<p>Use a descriptive subject line (eg parser library chokes on commas) rather than a vague one (eg. your code broke).</p>
+<p>Address a single issue in a report.</p>
+<p>Identify the CodeIgniter version (eg 3.0-develop) and the component if you know it (eg. parser library)</p>
+<p>Explain what you expected to happen, and what did happen.
+Include error messages and stacktrace, if any.</p>
+<p>Include short code segments if they help to explain.
+Use a pastebin or dropbox facility to include longer segments of code or screenshots - do not include them in the issue report itself.
+This means setting a reasonable expiry for those, until the issue is resolved or closed.</p>
+<p>If you know how to fix the issue, you can do so in your own fork &amp; branch, and submit a pull request.
+The issue report information above should be part of that.</p>
+<p>If your issue report can describe the steps to reproduce the problem, that is great.
+If you can include a unit test that reproduces the problem, that is even better, as it gives whoever is fixing
+it a clearer target!</p>
+</div>
+<div class="section" id="guidelines">
+<h2>Guidelines<a class="headerlink" href="#guidelines" title="Permalink to this headline">¶</a></h2>
+<p>Before we look into how, here are the guidelines. If your Pull Requests fail
+to pass these guidelines it will be declined and you will need to re-submit
+when you’ve made the changes. This might sound a bit tough, but it is required
+for us to maintain quality of the code-base.</p>
+<div class="section" id="php-style">
+<h3>PHP Style<a class="headerlink" href="#php-style" title="Permalink to this headline">¶</a></h3>
+<p>All code must meet the <a class="reference external" href="https://codeigniter.com/userguide3/general/styleguide.html">Style Guide</a>, which is
+essentially the <a class="reference external" href="https://en.wikipedia.org/wiki/Indent_style#Allman_style">Allman indent style</a>, underscores and
+readable operators. This makes certain that all code is the same format as the
+existing code and means it will be as readable as possible.</p>
+</div>
+<div class="section" id="documentation">
+<h3>Documentation<a class="headerlink" href="#documentation" title="Permalink to this headline">¶</a></h3>
+<p>If you change anything that requires a change to documentation then you will
+need to add it. New classes, methods, parameters, changing default values, etc
+are all things that will require a change to documentation. The change-log
+must also be updated for every change. Also PHPDoc blocks must be maintained.</p>
+</div>
+<div class="section" id="compatibility">
+<h3>Compatibility<a class="headerlink" href="#compatibility" title="Permalink to this headline">¶</a></h3>
+<p>CodeIgniter recommends PHP 5.6 or newer to be used, but it should be
+compatible with PHP 5.3.7 so all code supplied must stick to this
+requirement. If PHP 5.4 (and above) functions or features are used then
+there must be a fallback for PHP 5.3.7.</p>
+</div>
+<div class="section" id="branching">
+<h3>Branching<a class="headerlink" href="#branching" title="Permalink to this headline">¶</a></h3>
+<p>CodeIgniter uses the <a class="reference external" href="http://nvie.com/posts/a-successful-git-branching-model/">Git-Flow</a> branching model
+which requires all pull requests to be sent to the &#8220;develop&#8221; branch. This is
+where the next planned version will be developed. The &#8220;master&#8221; branch will
+always contain the latest stable version and is kept clean so a &#8220;hotfix&#8221; (e.g:
+an emergency security patch) can be applied to master to create a new version,
+without worrying about other features holding it up. For this reason all
+commits need to be made to &#8220;develop&#8221; and any sent to &#8220;master&#8221; will be closed
+automatically. If you have multiple changes to submit, please place all
+changes into their own branch on your fork.</p>
+<p>One thing at a time: A pull request should only contain one change. That does
+not mean only one commit, but one change - however many commits it took. The
+reason for this is that if you change X and Y but send a pull request for both
+at the same time, we might really want X but disagree with Y, meaning we
+cannot merge the request. Using the Git-Flow branching model you can create
+new branches for both of these features and send two requests.</p>
+</div>
+<div class="section" id="signing">
+<h3>Signing<a class="headerlink" href="#signing" title="Permalink to this headline">¶</a></h3>
+<p>You must sign your work, certifying that you either wrote the work or
+otherwise have the right to pass it on to an open source project. git makes
+this trivial as you merely have to use <cite>&#8211;signoff</cite> on your commits to your
+CodeIgniter fork.</p>
+<div class="highlight-bash"><div class="highlight"><pre><span></span>git commit --signoff
+</pre></div>
+</div>
+<p>or simply</p>
+<div class="highlight-bash"><div class="highlight"><pre><span></span>git commit -s
+</pre></div>
+</div>
+<p>This will sign your commits with the information setup in your git config, e.g.</p>
+<blockquote>
+<div>Signed-off-by: John Q Public &lt;<a class="reference external" href="mailto:john&#46;public&#37;&#52;&#48;example&#46;com">john<span>&#46;</span>public<span>&#64;</span>example<span>&#46;</span>com</a>&gt;</div></blockquote>
+<p>If you are using Tower there is a &#8220;Sign-Off&#8221; checkbox in the commit window. You
+could even alias git commit to use the -s flag so you don’t have to think about
+it.</p>
+<p>By signing your work in this manner, you certify to a &#8220;Developer&#8217;s Certificate
+of Origin&#8221;. The current version of this certificate is in the <a class="reference internal" href="../DCO.html"><em>Developer&#8217;s Certificate of Origin 1.1</em></a> file
+in the root of this documentation.</p>
