A single newline has no effect on the layout. These can be used to separate sentences within a paragraph. Some editors find that this aids editing and improves the diff function.

But an empty line starts a new paragraph.

You can break lines<br/>
without starting a new paragraph.

• Lists are easy to do:
  • start every line with a star
    • more stars means deeper levels

* Lists are easy to do:
** start every line with a star
*** more stars means deeper levels

1. Numbered lists are also good
   1. very organized
   2. easy to follow

• You can even do mixed lists
  1. and nest them
     • like this

• One item per line, NEWLINE only before the colon. The space before the colon improves parsing.

A colon indents a line or paragraph.

A manual newline starts a new paragraph.

• This is primarily for displayed material, but is also used for discussion on Talk pages.

 IF a line starts with a space THEN
   it will be formatted exactly 
     as typed;
   in a fixed-width font;
   lines won't wrap;
 ENDIF
 this is useful for:
   * pasting preformatted text;
   * algorithm descriptions;
   * program source code;
   * [[ASCII art]] and chemical structures;

WARNING If you make it wide, you force the whole page to be wide and hence less readable, especially for people who use lower resolutions. Never start ordinary lines with spaces.

• First letter of target is automatically capitalized.
• Internally spaces are automatically represented as underscores (typing an underscore has the same effect as typing a space, but is not recommended).

The same applies for the following feature.

• You can create it by clicking on the link.

• To create a new page:
  1. Create a link to it on some other page.
  2. Save that page.
  3. Click on the link you just made. The new page will open for editing.
• Have a look at how to start a page guide and Ireland Information Guide's naming conventions.

[[Ireland Information Guide:How to edit a page]] is this page.

Redirect one article title to another by putting text like this in its first line. Note that redirects to sections do not work yet. #REDIRECT [[United States#History]] will redirect to the United States page, but not to any particular section on it. It is possible this feature will be implemented in future, so such redirects could be used now for future compatibility.

#REDIRECT [[United States]]

Link to a page on the same subject in another language using a link like [[language code:Title]].

It does not matter where you put these links while editing as they always show up in the same place when you save the page, but placement at the end of the edit box is recommended. See Ireland Information Guide:Interlanguage links and list of languages and codes.

To include links to non-image uploads such as sounds, use a "media" link.

• Only images that have been uploaded to Ireland Information Guide can be used. To upload images, use the upload page. You can find the uploaded image on the image list.
• See Ireland Information Guide:Image use policy, Image markup and extended image syntax for more hints.
• Alternative text, used when the image isn't loaded, in a text-only browser, or when spoken aloud, is strongly encouraged. See Alternate text for images for help on choosing it.

A picture: [[Image:Wiki.png]]

or, with alternate text

[[Image:Wiki.png|jigsaw globe]]

or, floating to the right side of the page and with a caption.

[[Image:Wiki.png|right|jigsaw globe]]

or, floating to the right side of the page without a caption.

[[Image:Wiki.png|right|]]

Note the extra | after the word right. This is to make sure the image floats to the right side of the page, and not so that the alternate text is "right".

Clicking on an uploaded image displays a description page, which you can also link directly to: Image:Wiki.png

To include links to images shown as links instead of drawn on the page, use a "media" link.
