This project provides a unified setup script for Debian/Ubuntu and Fedora.
If you're on a Debian-based distro (Ubuntu, Pop!_OS, Linux Mint, etc...), Fedora or Arch-based:
chmod +x install_deps.sh
./install_deps.sh
npm run tauri dev
This works for both fish and bash !
You could go to tauri documentation for tauri dependencies,
Then install rustup:
# For general distributions
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
You may also need llvm-libs and lld for rustc.
Optionally setup fast node manager:
curl -fsSL https://fnm.vercel.app/install | bash
export PATH="$HOME/.local/share/fnm:$HOME/.fnm:$PATH"
eval "$(fnm env)"
fnm install --lts
fnm default --lts
Install node.js dependencies:
npm install
Build the project:
npm run tauri dev # development mode
Now you can even customize the launcher to your liking, you can go check the tutorial on how to create a theme in doc/theme_creation.md

The last one is a special theme, come on Discord to get it
Here are a few of the default themes ! You can then create as much as you want. Good luck !!
