+This article is divided into two parts: (i) Install Arch in WSL, (ii) Configure as per your needs. Each part can be followed independently so if you are not a fan of GUI programs in WSL, leaving the part is perfectly fine.
+
+## Part 0: FOr those running Windows 10 2004 or above
+Download and install Linux kernel updae package from [Microsoft's site](https://docs.microsoft.com/en-us/windows/wsl/wsl2-kernel). Set default version to WSL2 by running
+```powershell
+wsl --set-default-version 2
+```
+
+## Part I: Installation
+### Automated installation
+Assuming you have [Scoop](https://scoop.sh/) installed, this part reduces to
+```powershell
+scoop install archwsl
+```
+
+### Manual installation
+Head to [https://github.com/yuk7/ArchWSL/releases](https://github.com/yuk7/ArchWSL/releases) and download the `.appx` and `.cer` files.
+
+Now double click the `.cer` file and follow the prompts to install the certificates neecssary for the installation of Arch WSL. When done, double-click the `.appx` file to install it.
+
+Once there, open Arch from Start menu and let it install. When done, you should see an installation complete message. If you encountered problems with the installation, see the issues at [https://github.com/yuk7/ArchWSL/issues](https://github.com/yuk7/ArchWSL/issues). If there is none, feel free to open an issue.

+
+## Part II: Configuration
+Open Arch again. It should be logged in as root.
+
+Uncomment the servers closest to your region in `/etc/pacman.d/mirrorlist`. Now run `pacman -Syyu` to fetch and install updates.
+
+If you get `invalid or corrupted package (PGP signature)` error, do not delete the downloaded packages. Run the following commands one by one as root
+```bash
+rm -R /etc/pacman.d/gnupg
+rm -R /root/.gnupg/
+gpg --refresh-keywordspacman-hey --init && pacman-key --populate archlinux
+pacman -S archlinux-keyring
+pacman -Syyu
+```
+It should install fine.
+
+### Create a normal user account
+Running everything as root on a normal machine is a pretty stupid idea. Create a normal user:
+```bash
+useradd -m -g users -G wheel,storge,power -s /bin/bash <username>
+```
+It will add a user with whatever you used in `<username>`. Set a password for this user with
+```bash
+passwd <username>
+```
+Uncomment the following line after running `visudo`:
+```
+%wheel ALL=(ALL) ALL
+```
+
+### Time to install a Desktop Environment
+First, we install `xorg`, `xorg-server` and then `xfce4`. You may install a desktop environment of your choice.
+```bash
+pacman -S xorg xorg-server
+pacman -S xfce4
+export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2; exit;}'):0.0
+export LIBGL_ALWAYS_INDIRECT=1
+```
+
+While the DE is being installed, grab [VcXsrv](https://sourceforge.net/projects/vcxsrv/) or (again) you should be fine with your favourite X Server. Alternativaly it can be installed via scoop with
+```powershell
+scoop install vcxsrv
+```
+
+Hit *Win+Q*, type *XLaunch* and hit Enter. Once there, select *One Large Window* (just for the sake of it, if you wish to see the DE in action). Check *Disable access control*, leave the rest as is and click *Next* ad then *Finish*. Allow access if prompted by firewall.
