To make an advancement, first go to the "minecraft" folder. On Windows, it will be called ".minecraft" inside the "AppData" folder and to get there go to your start menu and type in "%appdata%". On a Mac, it is called "minecraft" and you can find it by going to Finder, pressing Shift-Command-G and typing "~/Library/Application Support/minecraft". Under Linux it is called ".minecraft" and is in your home directory (hidden by default).

Once you're inside the "minecraft" folder, go to the "saves" folder and from there pick the world for which you want to create an advancement. Go to the "data" folder of the world and open the "advancements" folder. In this "advancements" folder, create a new folder with any name you want. This folder will be the namespace of your advancement.
