Installing Texture Packs

The following explanations assume that you have a minetest version like the one you find on this page: http://minetest.net/download
Download the texture pack. If it is zipped (it probably is), unzip it and move the folder from within the archive to one of the following locations.

Windows 5 (XP) - 8

You will find a folder called textures in your minetest base folder. Place the texture pack there.

Linux (tested in Ubuntu, but probably is the same for most distributions)

Find the folder ~/.minetest (so ~ is your home directory and .minetest means it is a hidden folder within your home directory - you might have to access it by pasting that path to your directory browser's adress bar)
Place the texture pack within the ./textures folder

Start Minetest and select a new style in the Textures tab!
