New to Garry's Mod? Want to add some of those cool addons which your friends have been using, such as the quite annoying, but fun to use, Vuvuzela addon? Installing addons to Garry's Mod is fairly simple. Read on to learn how!

Steps

1
Begin by choosing the addon which you would like to use on Garry's Mod. Addons can be downloaded from various websites, the most popular of which is GarrysMods.org.
2
Once you have chosen the addon you wish to install, download both it and any other necessary files.

3
If the file(s) is/are zip/rar files, use a file extraction program such as WinRAR to un-zip/rar them; otherwise, leave them alone.
4
If the file(s) came with installer(s) use such programs to install the addon hassle-free. If not, they will typically have several files contained within a main folder (please note: some addons may have unnecessary folders containing the main folder, in such a case you should remove the main folder from the folders containing it.) Extract this main folder to c:\program files\steam\steamapps\yoursteamname\garrysmod\garrysmod\addons.

Question

How can I do this in a less complicated way?

Community Answer

Press shift+tab in-game. This should bring up a steam overlay. Click the "workshop" button in the right-top corner. This should open up a workshop where you can find and download add-ons to your game for free, simply by clicking the download button.
Question

How do I install an add-on if it's a .rar file with Windows 10?

Community Answer

First, you unzip your add-on with 7zip (Free Program). A RAR/ZIP/7z file is an archive file which compresses your add-ons to reduce download bandwidth. Once the files are unzipped, you can install them as described in the article.

What if my GMod is not on steam?

If you are talking about the Half-Life 2 mod version, GMod add-ons/mods can be installed the same way. This does not work on pirated versions.
