+## Why Alpine Linux?
 
  Alpine Linux is small and simple, realising the UNIX spirit to the core: doing one thing and doing it well. It uses its own package manager apk, the OpenRC init system and script driven setups. It is designed with minimalism at its best, enabling easier maintenance for security. Because of its lightweightness Alpine has been very popular for containers, and we think its beauty can benefit running with servers and desktops.
