 # Filesystem of boot partition
 
-We are now gonna put a filesystem on the first parition, I use FAT partitioning beacuse it is versatile since it's compatibile with both legacy boot and UEFI.

+# (optional) Change mirrors
+You might want to change the mirrors order to make installation of packages faster by going into this file (use your favorite text editor):
+```
+/etc/pacman.d/mirrorlist
+```
+From the list, move the servers that are closer to you to the top so that they will be the first ones to be chosen.
+
+# Install packages into the system
+Install the needed packages into the ```/mnt``` partition, add what you know you will need:
+```
+pacstrap /mnt base base-devel linux-libre linux-libre-firmware btrfs-progs grub networkmanager cryptsetup lvm2 vim neovim
+```
+If youre in UEFI then add the following package: ```efibootmgr```
+
+- base and base-devel:\
+base is the basic system and all the tools related to it, base-devel is necessary to compile packages and other stuff
+- linux-libre:\
+the libre version of the linux kernel, with no binary blobs, obfuscated code, or code released under proprietary licenses
+- linux-libre-firmware:\
+Some hardware devices such as the popular NetGear WNA1100 (aka: Wireless-N 150, aka: Atheros AR9271) require firmware (eg: ath9k_htc) from the linux-libre-firmware package
+- grub:\
+the boot loader
+- networkmanager:\
+internet 'n stuff
+- cryptsetup and lvm2:\
+packages needed for encrypting and decrypting the drive
+- vim and neovim:\
+i mean you know why
+
+# Chroot into your system
+```
+arch-chroot /mnt bash
+```
+
+# Set the timezone and set the hardware clock
+just run:
+```
+ln -s /usr/share/zoneinfo/Europe/Rome /etc/localtime
+```
+
+Change country adn city based on your correct timezone
+Then synch the hardware clock with the system clock:
+```
+hwclock --systhoc
+```
+
+# Setup keyboard layout and language
+Edit the locale.gen file:
+```
+nvim /etc/locale.gen
+```
+Uncomment the your langage and layout of choice
+
+Edit the file locale.conf:
+```
+nvim /etc/locale.conf
+```
+I will add the setup for the US keyboard but you might want a different layout:
+```
+export LANG="en_US.UTF-8"
+export LC_COLLATE="C"
+```
+Run the locale-gen command:
+```
+locale-gen
+```
+# Name your computer
+Run:
+```
+echo "myhostname" > /etc/hostname
+```
+
+change **myhostname** with your desired name, then edit the following file:
+```
+nvim /etc/hosts
+```
+and add the follwing lines:
+```
+127.0.0.1   localhost
+::1         localhost
+127.0.1.1   myhostname.localdomain myhostname
+```
+
+# Enable NetworkManager service
+run:
+```
+systemctl enable NetworkManager.service
+```
+
+# Add a user and set his groups and password
+First add a password to your root with:
+```
+passwd
+```
+Then create a new user:
+```
+useradd -G wheel -m user
+```
+this way a user by the name of **user** has been created, added to the wheel group and a home directory has been created for him
+Set the user user password:
+```
+passwd user
+```
+
+# Edit the mkinitcpio configuration
+Edit the **mkinitcpio.conf** file:
+```
+nvim /etc/mkinitcpio.conf
+```
+look for the line in which hooks are declared, it is going be like this:
+```
+HOOKS=(base udev autodetect modconf kms keyboard keymap consolefont block filesystem fsck)
+```
+add to the hooks **encrypt** and **lvm2**:
+```
+HOOKS=(base udev autodetect modconf kms keyboard keymap consolefont block encrypt lvm2 filesystem fsck)
+```
+**Optionally** you can add the following modules to same mkinitcpio.conf file:
+```
+hid usbhid hid_generic ohci_pci
+```
+If, at the end of the installation, the keyboard is not working during the decryption of the partition\
+
+Update the conf by typing:
+```
+mkinitcpio -p linux-libre
+```
+
+# Make the system able to decrypt the partition
+Start by exiting the partition:
+```
+exit
+```
+Create an fstab and output it in the correct place:
+```
+# genfstab -p /mnt >> /mnt/etc/fstab
+```
+use **-U** or **-L** to define by UUID or labels, respectively
+
+Take the output of **lsblk -f** in put it in the following file:
+```
+lsblk -f >> /mnt/etc/default/grub
+```
+Go back into your system:
+```
+arch-chroot /mnt bash
+```
+
+# Edit GRUB to make the system able to encrypt and decrypt the partition
+Enter the following file:
+```
+nvim /etc/default/grub
+```
+At the end of the file you will find the output of our **lsblk -f** command, it will be something similar to this:
+```
+NAME         FSTYPE FSVER LABEL UUID FSAVAIL FSUSE% MOUNTPOINTS
+sdb
+nvme0n1
+├─nvme0n1p1                     [UUID_0]      862.4M    16% /boot
+└─nvme0n1p2                     [UUID_1]
+  └─cryptlvm                    [UUID_2]      431.2G     9% /
+```
+You will only need the two UUIDs: **[UUID_1]** and **[UUID_2]**
 
 
+And at the top of this file there will be a line that looks like this:
+```
+GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet" 
+```
+Now, take the UUID of the encrypted partition (in this case the **UUID_1**) and add the following to the GRUB_CMDLINE_LINUX_DEFAULT:
+```
+cryptdevice=UUID=[UUID_1]:cryptlvm
+```
+It will look something like this:
+```
+cryptdevice=UUID=33dd1b52-a543-4143-8bf8-004390e411e0:cryptlvm
+```
+Take the UUID of the decrypted partition (in this case the **UUID_2**) and add the following to the GRUB_CMDLINE_LINUX_DEFAULT:
+```
+root=UUID=[UUID_2]
+```
+It will look something like this:
+```
+root=UUID=b720a64e-fdf2-462e-9231-d1a35ae2654e
+```
+the **GRUB_CMDLINE_LINUX_DEFAULT** should look like this:
+```
+GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet cryptdevice=UUID=33dd1b52-a543-4143-8bf8-004390e411e0:cryptlvm root=UUID=b720a64e-fdf2-462e-9231-d1a35ae2654e" 
+```
 
+# Install Grub bootloader
+Install GRUB for UEFI devices:
 
+**esp** denotes the mountpoint of the EFI system partition
+```
+grub-install --target=x86_64-efi --efi-directory=[esp] --bootloader-id=grub
+```
+
+Install GRUB for legacy BIOS devices
+```
+grub-install /dev/sdX
+```
+Then create the grub configuration:
+```
+grub-mkconfig -o /boot/grub/grub.cfg
+```
+
+Now you can unmount your partitions, remove your bootable device and reboot the system.
+You now a have a fully libre system, you chad.
+
+# Migrate to Open-RC
+For maximum chad-status you have to remote systemD in favour of Open-RC, the Parabola wiki has a section on how to do so [HERE](https://wiki.parabola.nu/OpenRC)
