After downloading the map file you want, open the archive (with WinRAR, 7-Zip, or any other software): you should see a folder with the name of the map (ex: “alcatraz-island”).
Unzip the archive and put the entire map folder (keep files inside!) into your Minecraft saves folder.
Launch the game, the map should be listed in “solo mode” maps.
If you don’t know where to find your Minecraft folder, please read this tutorial:

All our creations have been built on Minecraft Java Edition. We recommend its use as tests have been done on this version only.
Because other game editions are developed in a different code, we can’t tell if our maps are fully compatible or not with them.
