h1. Overview {anchor:id=KSuser.Wiki.Wiki_Overview}
This section provides you a guide to use all *Wiki* features and configure the *Wiki* portlet to make it work in your desired way. Before going further, you should know some basic concepts about *Wiki*.
After [accessing the *Wiki* application|#KSuser.access_knowledge], the *Wiki* homepage will appear automatically as below.

!images/wiki_overview.png|align="center"!

*Details*:
||Item|| Description||
|!images/no1.png!|The *Breadcrumb* which shows the page hierarchy.|
|!images/no2.png!|The Wiki administration area which allows administrators only to do space settings. |
|!images/no3.png!|The *Search* box.|
|!images/no4.png!|The pages tree view.|
|!images/no5.png!|The *Page Control* area which helps users take actions with the current page.|
|!images/no6.png!|The defaul content. The small page could be a Wiki quick guide that explains how to create a page, switch between different edit modes, or create a page, and more.|
|!images/7.png!|The page information. Click *View Change* to go to the *Page History* page for comparing changes between versions. Click *Attachment(s)* and *Revisions* links to open the *Attachments* details pane and the *Revisions* pane respectively right under the *Page information* bar. These two panes can be collapsed by clicking the relevant links again. |

h2. The page hierarchy in Wiki {anchor:id=KSuser.Wiki_Overview.Page_hierarchy}
*Wiki* is organized as a tree of pages in which each page may contain many sub-pages. The hierarchy is reflected on UI by the *Breadcrumb* and the page tree at the left pane. When a page is added, it is always defined as a sub-page to the current one. *Wiki* is a wiki platform which can host several wikis. So, you can have wikis for portals, wikis for groups or users. However, the page hierarchy is not reflected in the URLs as they are flatly accessible by their URLs.

h2. Wiki Spaces {anchor:id=KSuser.Wiki_Overview.Wiki_spaces}
Spaces represent a partitioning of *Wiki* data. A space is a set of pages. So, the space partitioning means they are independent trees. This separation is to enable *Wiki* to provide silos of knowledge for different interest groups.

There are 3 types of spaces:

* *Portal wiki*: wiki for the current portal.

* *Group wiki*: wiki available for members of a group.

* *User wiki*: wiki for personal pages.

{docbook}
<note>
    <para>
    In this document, Spaces are referred as wikis, particularly portal wikis, group wikis, and user wikis.
    </para>
    <para>
    Any space which has an implicit root page is named Wiki Home.
    </para>

h1. Work with Wiki pages {anchor:id=KSuser.Work_with_Wiki_pages}
Pages are sites where information in *Wiki* is stored and shared. Pages are stored within a *Space*. To do or view actions on a specific *Wiki* page, you should contact the administrator to get the appropriate permissions. See the [Page Permissions|#KSuser.Wiki_Administration.Page_permissions] for detailed permissions.

In a page, you can:

* [Create a page with its content using the simple markup language or the Rich Text editor|#KSuser.Work_with_Wiki_pages.Create_pages].

* [Edit a page|#KSuser.Work_with_Wiki_pages.Edit_pages].

* [Delete a page|#KSuser.Work_with_Wiki_pages.Delete_pages].

* [Move a page to another location|#KSuser.Work_with_Wiki_pages.Move_pages].

* [Watch a page|#KSuser.Work_with_Wiki_pages.Watch_pages].

* [View page information|#KSuser.Work_with_Wiki_pages.View_page_info].

h2. Create a page {anchor:id=KSuser.Work_with_Wiki_pages.Create_pages}
There are two ways to create a page:

*The first way* {anchor:id=KSuser.Work_with_Wiki_pages.Create_pages.First_way}

In this way, you need to use the toolbar.

*1.* Go to a Wiki space in which you want to create a page.

*2.* Click *Add Page* and select *Blank Page* or *From Template...* from the drop-down menu if you want to use an available template.

!images/add_wiki_page.png|align="center"!

If you select *From Template...*, a list of available templates appears.

!images/wiki_template.png|align="center"!

You can:

i. Click *Preview* corresponding to the template you want to see. The template preview appears:

!images/Wiki_template_preview.png|align="center"!

ii. Click *Select* corresponding to the template you want to select for your new page.

*3.* Enter the title for your page. The page title must be unique.

*4.* Enter the content for your page by using *Wiki Markup* or the *Rich Text* editor.

*5.* Optionally, click *Preview* to see how your page looks like.

*6.* Click *Save* to finish.

*The second way* {anchor:id=KSuser.Work_with_Wiki_pages.Create_pages.Second_way}

In this way, you need to use the undefined link in a page.

In the *Wiki* application of eXo Platform, you can add a link pointing to a page which you are going to create later. Such links are called undefined links. These links are often used to remind other *Wiki* users to create the page.

*Add an undefined link for creating a page later*

*1.* Add a link by typing the page title between square brackets '{noformat}[[...]]{noformat}' or '{noformat}[.... ]{noformat}' (depending on your selected syntax) into your page body.

For example:

||Syntax||What you type|| What you get||
|Xwiki 2.0 |{noformat}[[eXo User Guide]]{noformat}|!images/undefined_link.png!|
|Confluence 1.0|{noformat}[eXo User Guide]{noformat}|!images/undefined_link.png!|

*2.* Click *Save* to save the page containing the link. The undefined link is colored in red with the underline.

*3.* Click the created red link to open the 'Add Page' form.
