 You can either build the project using cargo build or install the `alma` package from AUR.

-### Using Arch Linux derivatives
-
-Using Arch Linux derivatives, is supported with this ALMA fork. You may edit the base.toml as needed.
-
 ## Usage

-### Image creation on removable device
 ``` shell
 sudo alma create /dev/disk/by-id/usb-Generic_USB_Flash_Disk-0:0
 ```
@ -31,154 +26,17 @@ sudo alma create /dev/disk/by-id/usb-Generic_USB_Flash_Disk-0:0
 This will wipe the entire disk and create a bootable installation of Arch Linux. You can use either
 removable devices or loop devices. As a precaution, ALMA will not wipe non-removable devices.

-Not specifying any path will cause ALMA to interactively prompt the user for a removable device.
-
-### Disk encryption
-
-You can enable disk encryption with the `-e` flag:
-
-``` shell
-sudo alma create -e  /dev/disk/by-id/usb-Generic_USB_Flash_Disk-0:0
-```
-
-You will be prompted to enter and confirm the encryption passphrase during image creation.
-
-### chroot
-
 After the installation is done you can either boot from it immediately or use `arch-chroot` to
-perform further customizations before your first boot (e.g. installing wireless device drivers).
+perform further customizations before your first boot.

-You can run `arch-chroot` via ALMA:
-
-``` shell
-sudo alma chroot /dev/disk/by-id/usb-Generic_USB_Flash_Disk-0:0
-```
-
-### Create raw image and boot in qemu
-
-For development and testing it may be useful to generate and boot the image in qemu.
-
-Creating a 10GiB raw image, with disk encryption:
-
-``` shell
-sudo alma create -e --image 10GiB almatest.img
-```
-
-If you receive the following error:
-```
-Error setting up a loop device: losetup: cannot find an unused loop device
-```
-
-Check that you are running ALMA with sudo privileges, and reboot if you have installed a kernel update since your last reboot.
-
-Mounting the raw image to a loop device:
-
-``` shell
-sudo losetup -f ./almatest.img
-```
-
-Check loop device:
-``` shell
- sudo losetup -j ./almatest.img
-```
-```
-/dev/loop0: [2070]:6865917 (/path/to/image/almatest.img)
-```
-Note that your loop device number may differ.
-
-Run qemu via ALMA:
-``` shell
-sudo alma qemu /dev/loop0
-```
-
-This will boot the image in qemu.
+Not specifying any path will cause ALMA to interactively prompt the user for a removable device.

 ## Presets

-Reproducing a build can be easily done using a preset file.
-
-Preset files are simple TOML files which contain:
-* A list of packages to install: `packages = ["mypackage"]`
-* A post-installation script: `script = """ ... """`
-* Environment variables required by the preset (e.g. used in the script): `enironment_variables = ["USERNAME"]`
-* A list of shared directories `shared_directories = ["subdirectory"]` - where subdirectory would be available at `/shared_dirs/subdirectory/` for use in the script of the preset.
-
-See the presets directory for examples.
-
-Presets are used via the `--presets` argument (multiple preset files or directories may be provided):
-
-``` shell
-sudo ALMA_USER=archie alma create /dev/disk/by-id/usb-Generic_USB_Flash_Disk-0:0 --presets ./presets/user.toml ./presets/custom_preset.toml
-```
-
-Preset scripts are executed in the same order they are provided.
-
-If a directory is provided, then all files and subdirectories in the directory are recursively crawled in alphanumeric order (all files must be ALMA .toml files). This allows you to use the following structure to compose many scripts in a specific order:
-
-```
-.
-├── 00-add_user.toml
-├── 01-xorg
-│   ├── 00-install.toml
-│   └── 01-config.toml
-└── 02-i3
-    ├── 00-install.toml
-    └── 01-copy_dotfiles.toml
-```
-
-Example preset TOML:
-
-``` toml
-packages = ["sudo"]
-script = """
-set -eux
-useradd -m ${ALMA_USER}
-passwd ${ALMA_USER}
-usermod -G wheel -a ${ALMA_USER}
-echo "%wheel ALL=(ALL) ALL" > /etc/sudoers.d/wheel
-"""
-environment_variables = ["ALMA_USER"]
-```
-
-Note that shared directories in the preset scripts are mounted as bind mounts, so they are *not* mounted read-only. Any changes the custom script makes to the shared directory will be carried out in the preset shared directory of the host system, so be sure to copy (not move) files from the shared directories.
-
-### Order of execution
-
-ALMA installs the packages and presets in the following order:
-
-1. All non-AUR packages are installed
-2. If AUR packages are present in the toml files, yay (or another
-   specified AUR helper) is installed
-3. All AUR packages are installed.
-4. Preset scripts are executed according to their filenames in
-   alphanumeric order.
-
-Note this may mean you have to workaround some package installations if
-they depend on preset scripts.
-
-For example, at the moment you cannot install Rust-based AUR packages in
-the `aur_packages` array of the Preset TOMLs if you use rustup,
-since rustup needs to be given the toolchain to
-install first. This can be worked around by carrying out the AUR
-package installation inside the preset script itself in these cases.
-
-## Troubleshooting
-### mkinitcpio: /etc/mkinitcpio.d/linux.preset: No such file or directory
-
-Ensure you have both the `linux` and `base` packages installed. Note
-that only Arch Linux is supported, not Arch Linux derivatives such as
-Manjaro.
-
-### Problem opening /dev/... for reading! Error is 123.
-
-Delete all partitions on the disk first (e.g. with gparted) and try
-again.
+Reproducing a build can be easily done using a preset file. Presets file are simple TOML file which
+contain a list of packages to install, a post-installation script and environment variables required
+by the preset. See the presets directory for examples.
