You can italicize text by putting 2 apostrophes on each side.

3 apostrophes will bold the text.

5 apostrophes will bold and italicize the text.

(Using 4 apostrophes doesn't do anything special --
they are just ' left over ones' that are included as part of the text.)

You can ''italicize text'' by putting 2

A single newline generally 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 (used internally to compare different versions of a page).

But an empty line starts a new paragraph.

When used in a list, a newline does affect the layout (see below).

Please use this sparingly.

Please do not start a link or italics or bold on one line and close it on the next.

Headings organize your writing into sections. The Wiki software can automatically generate a table of contents from them.

Using more "equals" (=) signs creates a subsection.

Don't skip levels, like from two to four equals signs.

Start with 2 equals signs not 1 because 1 creates H1 tags which should be reserved for page title.

• Unordered lists are easy to do:
  • Start every line with a star.
    • More stars indicate a deeper level.

  Previous item continues.

  • A newline
• in a list

marks the end of the list.

• Of course you can start again.

Here's a definition list:

Word 

Definition of the word

A longer phrase needing definition

Phrase defined

A word 

Which has a definition

Also a second one

And even a third

Begin with a semicolon. One item per line; a newline can appear before the colon, but using a space before the colon improves parsing.

A colon (:) indents a line or paragraph.

A newline starts a new paragraph.
Should only be used on talk pages.
For articles, you probably want the blockquote tag.

We use 1 colon to indent once.

We use 2 colons to indent twice.

3 colons to indent 3 times, and so on.

You can make horizontal dividing lines (----) to separate text.

But you should usually use sections instead, so that they go in the table of contents.

You can link to a page section by its title:

If multiple sections have the same title, add a number. #Example section 3 goes to the third section named "Example section".

You can make a link point to a different place with a piped link. Put the link target first, then the pipe character "|", then the link text.

• About Links
• Cities in Morocco

Or you can use the "pipe trick" so that a title that contains disambiguation text will appear with more concise link text.
