Install Archlinux is thing I always want to do for my laptop/PC since I had my laptop in ninth grade.
This is not a guide for everyone, this is just save for myself in a future and for anyone who want to taste a bit.
---
First thing as breathe air is to read [Installation guide](https://wiki.archlinux.org/index.php/Installation_guide). Read through the guide slowly and carefully.
After that, get an USB and follow [USB flash installation media](https://wiki.archlinux.org/index.php/USB_flash_installation_media). Use `dd` on Linux/MacOS or `Rufus` on Windows.
When booting Archlinux ISO, follow **Installation guide**, step by step.
In step **Connect to the internet**.
I mainly use Wifi with `wifi-menu`.
In step **Partition the disks**.
Use `cfdisk`.
Use `UEFI` if possible, and mount point `/mnt/efi` with `512 MiB`.
After finish **Installation guide**, don't rush to restart, read [General recommendations](https://wiki.archlinux.org/index.php/General_recommendations) to continue.
In step **System administration**.
Read [Users and groups](https://wiki.archlinux.org/index.php/Users_and_groups) to add new user, include [Sudo](https://wiki.archlinux.org/index.php/Sudo) and [Zsh](https://wiki.archlinux.org/index.php/Zsh).
In step **Graphical user interface**.
Display server - install [Xorg](https://wiki.archlinux.org/index.php/Xorg).
Remove line across screen when using Plank in Xfce: Settings Manager > Window Manager Tweaks > Compositor > **Uncheck** Show shadows under dock windows.
Center windows in Xfce: Settings Manager > Window Manager Tweaks > Placement > Move slider to full large and **Check** At the center of the screen.
