The CMS is very convenient for writing different kinds of articles. The main difficulty during articles creation is the usage of wiki markup at WikiEditor that provides specific framework with a set of feature-based modules, each of which can be selectively enabled or disabled, aiming to improve the user experience of editing and creating pages with so called wikitext. There is extra "VisualEditor" extension that provides simple tools to create or edit articles, especially for those who isn't familiar with wiki text. But this extension requires some technical knowledge to install it to your wiki website.

How to make new pages

WikiEditor has basic tools for page creation.

New pages or articles are made at WikiEditor by wiki markup. Wiki markup (also known as wikitext language or wikicode) is a lightweight markup language used to write pages at wiki-based websites (such as Wikipedia) that is a simplified/alternative/intermediate to HTML. Its purpose is to be converted by wiki software into HTML, which, in turn, is served to web browsers.[2]

There are several ways to start a new article:

  • First one: you can write article name in search bar and if there isn't such article on your website, the system offers you to create a page with this name. When you click the link to create a new page you see WikiEditor bar that provides with special tools for making new articles by wiki code.
  • Second one: You can download and install InputBox extension helps to start creating articles by entering a page name into the box.

During article creation WikiEditor has tools to make a page just like you want. It's very practical tool to create internal links of wiki website. You should put any word or phrase into square brackets - [[]]. After submitting the page you see such words has links. If there isn't such page on wiki website the words are in red colour otherwise in blue. If you click red links the system proposes to create such page.

To launch WikiEditor at website you shall insert following code to LocalSettings.php following configuration:

wfLoadExtension( 'WikiEditor' );
# Enables use of WikiEditor by default but still allow users to disable it in preferences
$wgDefaultUserOptions['usebetatoolbar'] = 1;
$wgDefaultUserOptions['usebetatoolbar-cgd'] = 1;
# Displays the Preview and Changes tabs
$wgDefaultUserOptions['wikieditor-preview'] = 0;
# Displays the Publish and Cancel buttons on the top right side
$wgDefaultUserOptions['wikieditor-publish'] = 0;

If you use Mediawiki version 1.25 and less you should to connect extension in LocalSetting file this way:

require_once ("$IP/extensions/WikiEditor/WikiEditor.php");

Using of templates in articles

Template — is the special informative thematic block that can be used as a standard texts in several articles on similar topic. Convenience of template usage is that they can be installed to various pages and display main information about a topic. Templates can be also used for navigation panels among articles of one common topic.

Templates are created as a separate page with its own namespace "Template:Template name" for example: Template:CMS - such template is used at all articles about content management system just like this one. Click the link to look through the core of template and understand how it is made. So to start making template you should indicate its name, e.g. Template:Test and inside of the page you should indicate what information should be used in it like that: {{{title}}} - the title of the template. Then it is possible to use the template at all pages using this code:

|title = 

After equal sign you should put some text for displaying in the article. As long as you create templates a lot of categories can be done as well as images etc, depending what information you would like to show in articles. It is possible to create dynamic and big templates that use images, tables and set how it all should look like on a page configuring CSS settings. General settings on design can be made on special page in mediawiki at Mediawiki:Common.css. Example templates can be found at any wiki website including WikiJournal or Wikipedia and they are free to be downloaded.
