## Installation guide (2020/12/18)
1. Check boot mode and connect to the internet(I usually use wire network for convinience)
```bash
ls /sys/firmware/efi/efivars
timedatectl set-ntp true

2. Disk allocation and format
```bash
fdisk -l
cfdisk /dev/sda
# Example
mkfs.ext4 /dev/sda1 # For normal partition
mkfs.fat -F32 /dev/sda2 # For EFI boot partition
```
3. Mount the partition
```bash
# Example
mount /dev/sda1 /mnt
mkdir /mnt/home
mkdir /mnt/boot
mount /dev/sda2 /mnt/home
```
4. Edit pacman mirror list(`/etc/pacman.d/mirrorlist`), choose or add the following line into it if you are Taiwaneese also. You can generate on Arch offitial [generator](https://www.archlinux.org/mirrorlist/), too.

## yay

## Chinese Input
* fcitx(2020/12/16)
1. Install: `sudo pacman -S fcitx-im fcitx-configtool fcitx-rime rime-luna-pinyin rime-cangjie librime librime-data`
2. Autoboot: `cp /etc/xdg/autostart/fcitx-autostart.desktop ~/.config/autostart`
3. Use rime: https://wiki.archlinux.org/index.php/Rime_(%E7%AE%80%E4%BD%93%E4%B8%AD%E6%96%87), set default as `luna_pinyin_tw`
Add a cutom config file in `.config/fcitx/rime/default.custom.yaml`
```
patch:
schema_list:
- schema: luna_pinyin_tw
- schema: cangjie5
```
`.pam_environment`
```
GTK_IM_MODULE DEFAULT=fcitx
QT_IM_MODULE DEFAULT=fcitx
XMODIFIERS DEFAULT=@im=fcitx
```
I don't know why when I just set `luna_pinyin_tw` can't work.
And Reboot the computer.
4. To show the chinese successfully, run `fc-cache -vf` before restart. If it still can't show it, try to install other fonts(noto-fonts-tc, adobe-source-han-sans-tw-fonts).

## Bluetooth for airpods
  After installing bluetooth, there are some problem make me can't use airpods.
1. `sudo pacman -S pulseaudio-bluetooth`
2. Modify `/etc/bluetooth/main.conf` $ControllerMode$ line to `ControllerMode = bredr`
3. To solve low volume(mention in arch wiki), run `systemctl edit --full bluetooth.service` and modify `ExecStart=/usr/lib/bluetooth/bluetoothd
` to `ExecStart=/usr/lib/bluetooth/bluetoothd --noplugin=avrcp`
4. After pairing successfully, $ControllerMode$ can reset back to original mode.
