-## Build and Run
+## Installation
+
+### Download from Releases
+The easiest way to install Lan Mouse is to download precompiled release binaries from the [releases section](https://github.com/feschber/lan-mouse/releases).
+
+For Windows, the depenedencies are included in the .zip file, for other operating systems see [Installing Dependencies](#installing-dependencies).
+
+### Arch Linux
+Lan Mouse is available on the AUR:
+```sh
+# git version (includes latest changes)
+paru -S lan-mouse-git
+
+# alternatively
+paru -S lan-mouse-bin
+```
+
+
+### Building from Source
+
+Build in release mode:
+```sh
+cargo build --release
+```
+
+Run directly:
+```sh
+cargo run --release
+```
+
+Install the files:
+```sh
+# install lan-mouse
+sudo cp target/release/lan-mouse /usr/local/bin/
+
+# install app icon
+sudo mkdir -p /usr/local/share/icons/hicolor/scalable/apps
+sudo cp resources/de.feschber.LanMouse.svg /usr/local/share/icons/hicolor/scalable/apps
+
+# update icon cache
+gtk-update-icon-cache /usr/local/share/icons/hicolor/
+
+# install desktop entry
+sudo mkdir -p /usr/local/share/applications
+sudo cp de.feschber.LanMouse.dekstop /usr/local/share/applications
+```
+
+### Conditional Compilation
+
+Currently only x11, wayland, windows and MacOS are supported backends.
+Depending on the toolchain used, support for other platforms is omitted
+automatically (it does not make sense to build a Windows `.exe` with
+support for x11 and wayland backends).
+
+However one might still want to omit support for e.g. wayland, x11 or libei on
+a Linux system.
+
+This is possible through
+[cargo features](https://doc.rust-lang.org/cargo/reference/features.html).
+
+E.g. if only wayland support is needed, the following command produces
+an executable with just support for wayland:
+```sh
+cargo build --no-default-features --features wayland
+```
+For a detailed list of available features, checkout the [Cargo.toml](./Cargo.toml)

 ### Gtk Frontend
 By default the gtk frontend will open when running `lan-mouse`.
