<p>Pencil Wiki is a simple wiki solution for your WordPress.</p>
<p>Basically, it adds new roles & capabilities that allow your users to add/edit wiki pages (custom post type).</p>
<p>It comes with several widgets and custom templates (that you can override) fully integrated with the <em>Twenty Twelve</em> theme.</p>
<p>Pages are edited backend, but there is a menu on every wiki page with the necessary links; and a wiki index / search input.</p>
<p>Only Administrators and Editors can create new wikis (top-level pages); and Wiki Authors can add pages to it.<br />
Administrators and Editors can also LOCK some wiki pages (for any reason) or branches; which means they will not be editable anymore by other users.</p>
<p>I voluntarily made the plugin quite simple to avoid making it intrusive (javascript, css, …) and put too many features. I recommend to run it with those plugins :<br />
* <a href="https://wordpress.org/extend/plugins/member" rel="ugc">Members</a>Members by Justin Tadlock, to manage roles and capabilities<br />
* <a href="http://mtekk.us/code/breadcrumb-navxt" rel="nofollow ugc">Breadcrumb NavXT</a> by John Havlik, to generate breadcrumbs<br />
* <a href="https://wordpress.org/extend/plugins/simple-footnotes" rel="ugc">Simple Footnotes</a> by Andrew Nacin, to put footnotes in your wiki pages.</p>
<p>WordPress has a revision system, which is perfect for a wiki.<br />
Unfortunately,  I didn’t find a way to customize it (add revision messages, etc).</p>

<p>Create an attractive and professional knowledge base or documentation. WP Knowledgebase is easy to use, easy to customize, and works with any theme.</p>
<h4>Why is a knowledge base important?</h4>
<ul>
<li><strong>Often, people prefer self-service</strong> – People often try to find answers on their own before contacting for help. A knowledgebase is where they look first.</li>
<li><strong>A knowledge base operates 24/7</strong> – Even if you have a distributed team, a knowledgebase will always be there for your users.</li>
<li><strong>A knowledge base acts like a brain for your support team</strong> – Your team members won’t know everything other team members know. A knowledgebase can bridge that gap and offer your team.</li>
<li><strong>It can lower costs</strong> – With standardized answers and all the information in one place, a knowledgebase can ensure new hires are trained quicker and better.</li>
</ul>

<h4>Important</h4>
<p>On activation, the plugin will create a page called “Knowledgebase” and on that page there will be the shortcode <code>[kbe_knowledgebase]</code>. If you want to change the slug of that page do so via the WP Knowledgebase settings.</p>
<h4>Advanced Customisation</h4>
<p>Developers, you can completely customise the way the WP Knowledgebase displays by copying the plugin templates to your theme and customising them there. You may be familiar with this method of templating as used by WooCommerce.</p>
<p>In the plugin’s root directory you will find a folder called <code>template</code>. You can override that folder and any of the files within, by copying them into your active theme and renaming the folder to <code>/yourtheme/wp_knowledgebase</code>. WP Knowledgebase plugin will automatically load any template files you have in that folder in your theme, and use them instead of its default template files. If no such folder or files exist in your theme, it will use the ones from the plugin.</p>
<p>This is the safest way to customise the WP Knowledebase templates, as it means that your changes will not be overwritten when the plugin updates.</p>
