How to install Minecraft Resource Packs
Download Minecraft Resource Pack
If this is HD Resource Pack, you have used the MCPatcher HD (or this wont function well). Open MCPatcher and click Patch. Make sure that the HD Textures option is selected. This only needs to be done once.
Open Minecraft and click Resource Packs on the main menu.

Linux: ~/.minecraft/Resourcepacks

Place the Resource pack in the folder leaving the file as a .zip.
The Resource pack will now show up in Minecraft. Simply click the pack and it will be applied to Minecraft!
