 # 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 | bash
+```
+
+This installs as dropshell for the local user, with a symbolic link ds.
+You'll need to run:
+```
+~/.local/bin/dropshell edit
+~/.local/bin/dropshell install
+source ~/.bashrc
+```
+to configure dropshell and install the local components.
+
+## Remote Server Setup
+
+### Initial setup
+
+Auto setup script which creates a dropshell user, and includes installing docker if not already present:
+```
+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.
+
+
+### Configure and Use Remote Server
+
+#### Add to local dropshell configuration, and install remote agent
+Back on the dropshell host:
+1. `dropshell create-server SERVERNAME`
+1. `dropshell edit SERVERNAME`
+1. `dropshell install SERVERNAME`
+
+#### Install Services
+Create and install a service
+1. `ds template list`  -- see what templates are available to install.
+1. `ds create-service SERVERNAME SERVICENAME TEMPLATE`
+1. `ds edit SERVERNAME SERVICENAME`
+1. Edit other config files if needed.
+1. `ds install SERVERNAME SERVICENAME`
+1. `ds list`
+
+The service should now be seen to be running.

+output.hpp and output.cpp - simple output helpers.
+
+Defines ostreams:
+
+debug, info, warning, error.
+
+These ostreams can be used with C++23 print and println, e.g.
+std::println(debug, "funny variable: {}={}","my_var",my_var);
+
+Also defines a few helper functions:
+
+PrintDebug(const std::string& msg);     // equivalent to std::println(debug, msg);
+PrintInfo(const std::string& msg);      // equivalent to std::println(info, msg);
+PrintWarning(const std::string& msg);   // equivalent to std::println(warning, msg);
+PrintError(const std::string& msg);     // equivalent to std::println(error, msg);
+
+Output for these streams for each line is formatted as:
+[DBG] <message>
+[INF] <message>
+[WRN] <message>
+[ERR] <message>
+
+The output is coloured, and the tag is printed in grey.
+
+In addition, when not using any of the above, helper routines for coloring the output of cout and cerr are provided.
