Installation on Arch is majorly untested and is not officially supported due to issues. Please keep this in mind when seeking support.

# Update system packages
sudo pacman -Syu

# Install dependencies
sudo pacman -S git python python-pip opus libffi libsodium ncurses gdbm glibc zlib sqlite tk openssl ffmpeg

# Clone the MusicBot to your home directory
cd ~
git clone https://github.com/Just-Some-Bots/MusicBot.git MusicBot -b master
cd MusicBot

# Install dependencies
pip install --upgrade pip
pip install --upgrade -r requirements.txt

Once everything has been completed, you can go ahead and configure the bot and then run with sh ./run.sh.
