 # Dropshell
 
 A system management tool for server operations, written in C++.
+
+## Installation
+
+```
+curl -fsSL https://gitea.jde.nz/public/dropshell/releases/download/latest/install.sh | sudo bash
+```
+
+This installs as dropshell, with a symlink ds if the ds command does not already exist.
+
+## Installation of Agent
+
+Install the Agent on each server you wish to manage. Supports amd64 (x86_64) and arm64 (aarch64) architectures.
+
+```
+curl -fsSL https://gitea.jde.nz/public/dropshell/releases/download/latest/server_autosetup.sh | sudo bash
+```
+
+Manual steps:
+1. `apt install curl wget jq`
+1. `curl -fsSL https://get.docker.com -o get-docker.sh && sh get-docker.sh && rm get-docker.sh`
+1. `useradd -m dropshell && usermod -aG docker dropshell && chsh -s /bin/bash dropshell`
+1. Put appropriate ssh keys in `/home/dropshell/.ssh/authorized_keys`
+1. Test ssh'ing into the server.
+
+
+## Install Services
+
+Set up a server and install a service:
+1. `ds create-server SERVERNAME`
