+
+### Format EFI Partition
+#### The efi partition (mounted at /boot/efi) Needs to be formatted as fat32
+mkfs.fat -F32 $EFI_PARTITION
+
+### Format SWAP partition
+mkswap $SWAP_PARTITION
+### Activate swap partition
+swapon $SWAP_PARTITION
+
+### Format Root Partition
+#### We will be formatting it with ext4 because that's the default for most use-cases, especially when new linux users are concerned
+mkfs.ext4 $ROOT_PARTITION
+
+### Mounting the root partition to begin setting up the partitions where they need to be
+mount $ROOT_PARTITION /mnt

+base:
+This is a meta-package. One that will handle installing many of the necessary programs to have a basic install of arch to chroot into
+
+
+linux:
+This is the actual kernel being installed. It will install the kernel & kernel-modules necessary to boot
+
+
+linux-headers:
+This is many other family of distros (Debian, RedHat, etc) would name linux-dev || linux-devel
+
+This is a package that contains all of the kernel's header files for compiling modules for your distrobutions kernel.
+
+
+linux-firmware:
+This is another meta package that contains just about all of the firmware drivers you system may need. It is just a dump of firmware, not all of them will be needed for your system.
+
+sudo:
+A program needed for privelege escalation. Basically to provide a user of an admin group (most often wheel in most distrobutions) to be able to execute binaries that require root level permissions in you system.
+
+Installing it here because it is not installed by default. An alternative is doas, a utility to perform the same funciton.
