### On Ubuntu and Debian-based systems:
1. Open a terminal.
2. Update your package list:
```bash
sudo apt update
```
3. Install KDE Plasma including KWin:
```bash
sudo apt install kde-plasma-desktop
```
### On Fedora:
1. Open a terminal.
2. Install KDE Plasma including KWin:
```bash
sudo dnf install @kde-desktop
```
### On Arch Linux:
1. Open a terminal.
2. Install KDE Plasma including KWin:
```bash

```
After installation, you can log out of your current session and select KDE Plasma as your desktop environment from the login screen.
