+## Installing Lazydocker
+
+Lazydocker is basically a CLI portainer. Rather than running a service for a single container running in LXC. I like to install lazy docker to manage things. Install is easy by using the script they provide, but I prefer to run my own.
+
+```bash
+#!/bin/bash
+
+# allow specifying different destination directory
+DIR="/usr/local/bin"
+
+# map different architecture variations to the available binaries
+ARCH=$(uname -m)
+case $ARCH in
+    i386|i686) ARCH=x86 ;;
+    armv6*) ARCH=armv6 ;;
+    armv7*) ARCH=armv7 ;;
+    aarch64*) ARCH=arm64 ;;
+esac
+
+# prepare the download URL
+GITHUB_LATEST_VERSION=$(curl -L -s -H 'Accept: application/json' https://github.com/jesseduffield/lazydocker/releases/latest | sed -e 's/.*"tag_name":"\([^"]*\)".*/\1/')
+GITHUB_FILE="lazydocker_${GITHUB_LATEST_VERSION//v/}_$(uname -s)_${ARCH}.tar.gz"
+GITHUB_URL="https://github.com/jesseduffield/lazydocker/releases/download/${GITHUB_LATEST_VERSION}/${GITHUB_FILE}"
+
+# install/update the local binary
+curl -L -o lazydocker.tar.gz $GITHUB_URL
+tar xzvf lazydocker.tar.gz lazydocker
+install -Dm 755 lazydocker -t "$DIR"
+rm lazydocker lazydocker.tar.gz
+```
+
+Now you can simply run it with the following command.
+
+```bash
+lazydocker
+```
