You can use the Upgrade Weapons menu and pick the equipment upgrades that give you extra Materia slots to expand this pool. This denotes your weapon's Materia capacity and will tell you how many you can slot into your item. Once there, if you pick out a piece of armour or a weapon, you should see that there are open circular slots underneath the ability descriptor. You can do this by opening the start menu and heading to the Materia and Equipment menu.

Once you've picked up some Materia, you'll need to carefully study each weapon's attunement slots. You'll see them everywhere, sometimes in the environment with a trail of light notifying the player that they can be picked up, otherwise they will appear in cutscenes or be embedded into the weapons of the main cast once attuned to their equipment. It is represented in-game as small brightly coloured balls that look like marbles. You'll get access to Materia as soon as you first get control of Cloud in Final Fantasy 7 Remake when you leap from the train car.
