Part 1: What is a Mod? 

A mod is a modification, aa added battlefield to Star Wars Battlefront,
changes in any of the units or their weaponry, and similar things like that.
There are many sites where you can upload mods, the most famous ones being SWBF Files
and Gametoast.

Part 2: Downloading

Downloading a Mod is very easy simply click the DOWNLOAD link at the bottom of the page 
(The one at the top will usually just bring you to the bottom), and then click download on the download
page. If pop-up blocker does not let you download, there is a message that says "click here if the window
won't show up" or something like that. Sometimes Mods may take a long time to download, depending on their
content.

Part 3: Types of Mods and Installing Them

Maps: These are the main types of Mods you will encounter before you read please note some mods (any kind) have
installers that you run to install the mod without having to do any work. Anyway, usually you have to
unzip the folder you download (If its a RAR file you must have WinRar), and then inside the folder 
should be another folder and a document called "Readme." The Readme files tell you info about the mod and 
details about, and usually tell you how to install it. The other file is the map. To add it simply go to "My 
Computer" in the start menu at the bottom right of your screen, the go to Local Disc C, then Program Files,
the LucasArts, then StarWarsBattlefront, the Gamedata, and then go into the folder Addon (If you
don't have one make one) and put the map in there.

SIDE changes: SIDE changes change the units or the units weaponry. Sometimes SIDE change mods even tweak levels
on your Battlefront allowing you to play as unavailable temas, such as the Empire and the Rebels on Geonosis,
and The Clones and Battle Droids on Hoth. You usually have to back up a file in your Data Folder, which is in 
the same place as Addon; the GameData Folder of your StarWars Battlefront (go to "My 
Computer" in the start menu at the bottom right of your screen, the go to Local Disc C, then Program Files,
the LucasArts, then StarWarsBattlefront, the Gamedata, and then go into the folder "Data"), and replace the file
with a new version of it. For example, for HyperShadowTheHedgehog's Clone and droid remix, you have to
replace the cis.lvl and rep.lvl in the SIDE folder in the Data folder with the new versions. Backing up a file means
putting it somewhere else incase you want to get rid of the new mod. Usually Readme's give you more detailed
directions of what you need to do.

Part 4: Equipment

For you to add and isntall mods and maps, you will need:

The most up-to-date-version of Star Wars Battlefront. That means you need the required Patches to install mods.
I will cover Patches later. 

An Addon Folder. Put it where it needs to go.

A back-up Folder. You need it to put your backed-up files in. There is no
specific place you need to put it, just as long as you remember whre it is; I suggest you put it in the Data Folder.

A Folder for unnused Mods. The more mods you have, the slower your Battlefront will be. To avoid this just
insert any mods that you don't really play in here, and put them back into the addon folder when you want to
use them again.I suggest you put it in your Addon Folder so you can
just take the mods right out whenever you feel like it.

Jabba's Palace. Jabba's Palace is the first mod map for Battlefront ever made. It was developed by LucasArts
themselves and is a must-have for beginning mod-users. If you do not have it, get it. 

Part 5: Patches

If you have Star Wars Battlefront (NOT THE BEST OF PC!) You need to read this. If you have Best of Pc you do not
need any patches; as your version of Battlefront is the most up-to-date. It even includes Jabba's Palace.
Anyway, A patch lets you install mods, and improves gameplay in the game, and fixes bugs in the game. If you
find you cannot install any Mods, or they won't work, etc., search for patches made by LucasArtsEntertainment.
These are official patches. Download them and follow the directions or use the installer. Whatever one the Patches
have.

Part 6: Farewell

Now that you know how to install and add mods and maps (sob, they grow up so fast...), you can begin 
doing your stuff. I know there aren't too many SWBF maps out that often, with the second Game SWBF2 already out and
SWBF3 just around the corner (I heard its coming out fall 2009). But some recents maps for SWBF include:

-Republic Commando Mission 1
-Geonosis Hills
-Star Fire Side Mod

So to all of you, I say, good luck, and may the force be with you all.
