When using the Add-on Manager (http://lussumo.com/addons) to upload your add-ons for Vanilla, you must follow these guidelines:

• You must be a registered member of the Lussumo Community.
• Make sure that the name and version you specify on the add-on site match the values in your default.php file or the update checker will not work!
• Make sure you update your version number every time you update your add-on.
• Your add-on must be an archive file (zip, rar, or gzip) and it must contain all files required to install your add-on.
• When uploading your add-on, you will be required to supply a screenshot (200px wide by 150px high) in gif, jpeg or png format.
• Your add-on file must include a readme file (text or html, it is up to you) explaining how to install your add-on. If your add-on does not require any special instructions, you must still provide basic install instructions. There are sample readme contents below which you can copy & paste into your readme file.
• New themes must contain a default style.
• New language readme files should (of course) be translated to the language being defined. Please see the sample language readme contents below.
• Name your add-on file like so: add_on_name.zip. We will give the file a timestamp when it is uploaded.
• Misuse of the Add-on Management service in any way will result in immediate banishment from the Lussumo Community.

===================================
EXTENSION INSTALLATION INSTRUCTIONS
===================================

In order for Vanilla to recognize an extension, it must be contained within its
own directory within the extensions directory. So, once you have downloaded and
unzipped the extension files, you can then place the folder containing the
default.php file into your installation of Vanilla. The path to your extension's
default.php file should look like this:

/path/to/vanilla/extensions/this_extension_name/default.php

Once this is complete, you can enable the extension through the "Manage
Extensions" form on the settings tab in Vanilla.

===============================
STYLE INSTALLATION INSTRUCTIONS
===============================

In order to enable this style, you must first place the style in the correct
folder in Vanilla. Every style works only for specific themes, so make sure that
you place this style in the correct theme's style folder by checking the
lussumo.com/addons listing for this style.

The path to this style's folder & contents should be as follows:

/path/to/vanilla/themes/theme_name/styles/style_name/vanilla.css

Once you have copied the files to the correct place in Vanilla, you can then 
enable the style in Vanilla using the **Themes & Styles** form on the settings 
tab.

===============================
THEME INSTALLATION INSTRUCTIONS
===============================

Your new theme files should be placed within their own folder in the themes
directory of Vanilla. The path to your new theme should be as follows:

/path/to/vanilla/themes/theme_name/

Once you have placed your theme in the correct place, you can apply the theme
using the **Themes & Styles** form on the settings tab.

==================================
LANGUAGE INSTALLATION INSTRUCTIONS
==================================

Now that you have your language file, you must place it in Vanilla's language
folder. Your language file should be contained within its own folder. The path
to your language file should be similar to this:

/path/to/vanilla/languages/language_name/definitions.php

Once your language is in the correct place, you can enable it in the settings
tab's "Language Management" form.
