-## Never used a terminal? Start here
+## Quick start
 
-If the commands below look intimidating, they're friendlier than they look.
+**1. Open a terminal.** Press the Super key (the one with the Windows logo),
+type `terminal`, press Enter. Paste each command below with **Ctrl+Shift+V**
+(plain Ctrl+V doesn't work in a terminal), then press Enter. If it asks for
+your password, type it — nothing shows while you type, that's normal.
 
-The **terminal** is a window where you type commands instead of clicking. On
-most Linux desktops you open it by pressing the Super key (the one with the
-Windows/Command logo) and typing "terminal". (On a Mac it's Terminal, from
-Spotlight; on Windows it's PowerShell, from the Start menu — but read the
-Mac/Windows note under *What you need* first.) Everything in a grey box below is
-meant to be **copied and pasted** into that window — paste it, press Enter,
-done. You don't need to understand a command to run it.
+**2. Install what LinTunes needs.** Paste the line for your Linux (not sure?
+it's probably Ubuntu or Mint):
 
-Two bits of shorthand that show up everywhere:
+```sh
+# Debian / Ubuntu / Mint
+sudo apt install git python3-pyqt6 python3-pyqt6.qtmultimedia python3-mutagen python3-numpy python3-requests
+```
 
-- **`~`** means your home folder. `~/Music` is just the Music folder inside your
-  home folder — the same one your file manager shows you.
-- **Your "distro"** is which flavour of Linux you're running (Ubuntu, Fedora,
-  Debian, Mint…). If you don't know, it's almost certainly Ubuntu or Mint, and
-  you want the **Debian/Ubuntu** instructions below.
+```sh
+# Fedora
+sudo dnf install git python3-pyqt6 qt6-qtmultimedia python3-mutagen python3-numpy python3-requests
+```
 
-If a command fails, nothing is broken — copy the error into a search engine, or
-ask whoever pointed you here. You cannot damage your music by running these.
+**3. Download LinTunes** into a `lintunes` folder in your home folder:
 
-## What you need
+```sh
+cd ~
+git clone https://git.autonomic.zone/trav/lintunes.git
+cd lintunes
+```
 
-Linux, Python, and a handful of free add-ons. **Nothing to compile, no account
-to make, no database to set up, nothing that phones home.** LinTunes keeps your
-library as ordinary files on your own computer.
+(That link is the **HTTPS** address from the clone box on the project page —
+if you copy it yourself, pick HTTPS, not SSH.)
 
-In detail:
+**4. Add it to your app menu and start it:**
 
-- **Linux** with Python **3.11 or newer** (already installed on essentially
-  every Linux machine — check with `python3 --version`)
-- **PyQt6** (including its QtMultimedia part), **mutagen**, **numpy**, **requests**
-- The **FFmpeg codecs for Qt Multimedia**. Without these the window opens fine
-  but nothing plays — so if you get a silent LinTunes, this is the thing that's
-  missing. They come from `qt6-qtmultimedia` built with ffmpeg (Fedora: enable
-  RPM Fusion; Debian/Ubuntu: it comes along with `python3-pyqt6.qtmultimedia`).
+```sh
+bash packaging/install-desktop.sh
+mkdir -p ~/Music/lintunes
+python3 -m lintunes.main --data-dir ~/Music/lintunes --save-config
+```
 
-**On a Mac or on Windows?** LinTunes is only built and tested on Linux and
+It asks once where to keep your music (`~/Music` is fine). Add songs with
+**File ▸ Add Files to Library**, or drag folders onto the window. From now on,
+open LinTunes from your app menu like any other app.
+
+Coming from iTunes? Replace the last line with the one in
+*Importing an existing iTunes library* below.
+
+**Updating:** click the version number at the bottom of the window.
+
+**Window opens but nothing plays?** Your system is missing audio codecs. On
+Fedora, enable [RPM Fusion](https://rpmfusion.org/Configuration), then run
+`sudo dnf swap ffmpeg-free ffmpeg --allowerasing`.
