 # Alpine Linux
 Alpine Linux is a lightweight and secure [Linux](Linux.md) operating system designed for security, simplicity, and resource efficiency. It is particularly popular for use in containerized environments and embedded systems. Alpine does not use [Systemd](Systemd.md), instead it uses [openrc](openrc.md).

+Here are some of the features of Alpine Linux:
 -   Lightweight: Alpine Linux is designed to be as small and simple as possible, with a small footprint and minimal dependencies. The base image is typically around 5 MB in size.
 -   Security-focused: Alpine Linux uses the musl libc library and includes security features such as hardened kernel and stack protector. The default package manager, apk, is designed to prevent privilege escalation attacks and is based on signed packages.
 -   Resource-efficient: Alpine Linux is optimized for resource efficiency and can run on low-power devices and in resource-constrained environments.
