+# Intro
+
+[Yggdrasil](https://yggdrasil-network.github.io/about.html) is a new experimental compact routing scheme. It is designed to be a future-proof and decentralised alternative to the structured routing protocols commonly used today on the Internet, as well as an enabling technology for future large-scale mesh networks. The current implementation of Yggdrasil is a lightweight userspace software router which is easy to configure.
+
+# Usage
+
+The container generates new Yggdrasil config if empty. And automatically update available public peers in the Yggdrasil configuration file with [peers_updater](https://github.com/ygguser/peers_updater) at every start.
+
+Here are some example snippets to help you get started creating a container.
+
+## docker-compose
+
+```yaml
+services:
+  yggdrasil:
+    cap_add:
+      - NET_ADMIN
+    devices:
+      - /dev/net/tun
+    volumes:
+      - "./yggdrasil:/etc/yggdrasil"
+    sysctls:
+      - "net.ipv6.conf.all.disable_ipv6=0"
+```
+
+## docker cli
+
+```sh
+docker run \
+--rm \
+--cap-add "NET_ADMIN" \
+--device "/dev/net/tun" \
+--volume "./yggdrasil.conf:/etc/yggdrasil/yggdrasil.conf" \
+--sysctl "net.ipv6.conf.all.disable_ipv6=0" \
+--mac-address "52:2a:ed:47:e9:25" \
