Section Heading

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.
• A newline
• in a list

marks the end of the list.

• Of course you can start again.

1. Numbered lists are:
   1. Very organized
   2. Easy to follow

A newline marks the end of the list.

1. New numbering starts with 1.

Another kind of list is a definition list:

Word 

Definition of the word

Here is a longer phrase that needs a definition

Phrase defined

A word 

Which has a definition

Also a second one

And even a third

Another kind of list is a ''definition list'':
; Word : Definition of the word
; Here is a longer phrase that needs a definition
: Phrase defined
; A word : Which has a definition
: Also a second one
: And even a third

• You can even do mixed lists
  1. and nest them
  2. inside each other
     • or break lines
       in lists.

     definition lists

     can be

     nested too

A colon (:) indents a line or paragraph.

A newline after that starts a new paragraph.
This is often used for discussion on talk pages.

We use 1 colon to indent once.

We use 2 colons to indent twice.

We use 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.

We may use the ref or refun tag. Eg:
There are XX numbers of people in the world.^[1]

1. ↑ The source is quoted from ...

For details, see Help:References.

Sometimes you may need to reference or add supplementary 
notes to your sentences.
We may use the ref or refun tag. Eg: <br>
There are XX numbers of people in the world.<ref>The 
source is quoted from ...</ref> <br>

Reference: <references/>

For details, see [[Help:References]].

A single newline has no effect on the layout. But an empty line

starts a new paragraph.

You can break lines
without a new paragraph.
Please use this sparingly.

You should "sign" your comments on talk pages:
- Three tildes gives your user name: Karl Wick
- Four tildes give your user name plus date/time: Karl Wick 07:46, 27 November 2005 (UTC)
- Five tildes gives the date/time alone: 07:46, 27 November 2005 (UTC)

<nowiki>
The nowiki tag ignores Wiki ''markup''.
It reformats text by removing
newlines    and multiple spaces.
It still interprets special
characters: &rarr;
</nowiki>

<pre>
The pre tag ignores Wiki ''markup''.
It also doesn't     reformat text.
It still interprets special characters: &rarr;
</pre>

The pre tag ignores Wiki ''markup''.
It also doesn't     reformat text.
It still interprets special characters: →

Leading spaces are another way to preserve formatting.

 Putting a space at the beginning of each
 line stops the text   from being reformatted.

#A <nowiki>newline
surrounded by nowiki tags
in a list
does not mark the end of the list.
</nowiki><pre><nowiki>
You can combine pre tags with nowiki
tags so preformatted examples can go
inside of lists.
</nowiki></pre>
#The list continues.

1. A newline surrounded by nowiki tags in a list does not mark the end of the list.
