# Instalador automatico de los mods de project.paquitoservers.sbs
# ---------------------------------------------------------------
# Descarga los 96 articulos del Steam Workshop que usa el servidor y los deja
# en la carpeta de Workshop de tu Steam, para que Project Zomboid los cargue
# solo al entrar.
#
# Uso:
#     bash -c "$(curl -fsSL https://project.paquitoservers.sbs/install/install.sh)"
#
# O descargalo y ejecutalo:
#     curl -fsSL https://project.paquitoservers.sbs/install/install.sh -o install.sh
#     bash install.sh
#
# No modifica nada de tu Steam: solo escribe en
# Steam/steamapps/workshop/content/108600, que es donde el juego ya busca
# los mods.
