Installing skins in CS:GO is more difficult and requires (basic) hex/binary knowledge.
This tool saves you a lot of time by doing the edits and all you have to do is extract the skin to your CS:GO directory like a good old CS:S skin.
Before you start:Already have custom skins installed?
Restore your backup of pak01_dir.vpkor
Delete pak01_dir.vpk from your CSGO directory and verify your cache to make steam restore the original file.
Manually installed do not work with this tool and you will not be able to uninstall the skins again via this tool.
