-# Installation
+## Supported OS
+
+Only Arch Linux is supported
+
+## Bootstrapping
+
+Bootstrapping is specific to the exact machine that is installed. See
+`_machines/` for machine-specific configuration, and `install_scripts/` for the
+machine install scripts.
+
+They are keyed by hostname.
+
+For easier installation, the install scripts are available via shortlinks. To
+(re)install a new machine from a Arch live environment:
+
+```
+curl --proto '=https' -sSfL https://s.hkoerber.de/i/${hostname}.sh | bash
+```
