### <a name="Setting_and_Creating_New_Prefere"> Setting and Creating New Preferences </a>

* The syntax for Preferences variables is the same anywhere in TWiki. In Edit mode, from the start of a new line: <br />[6 spaces] \* [space] Set [space] VARIABLENAME [space] = [value] <br />**_Example:_**
  * <code>**Set VARIABLENAME = value**</code>
* You can add your own preference variables for an entire site, a single web, or a single topic, using the standard syntax. Whatever you include in your variable will be expanded on display, and treated exactly as if it had been written out. So you can place formatted text, page links, images.<br />**_Example:_** To place a logo anywhere in a web by typing <code>**%MYLOGO%**</code>, define the variable in the web's [[WebPreferences]] topic, like this (in this case, you also have to upload <code>**logo.gif**</code> to the same directory):
  * <code>**Set MYLOGO = %PUBURLPATH%/%MAINWEB%/LogoTopic/logo.gif**</code>
