+# GtS CLI Tool
+
+GoToSocial compiles to an executable binary.
+
+The standard way of using this binary is to run a server with the `gotosocial server start` command.
+
+However, this binary can also be used as an admin tool.
+
+Here's the full output of `gotosocial --help`, without the big list of global config options.
+
+```text
+NAME:
+   gotosocial - a fediverse social media server
+
+USAGE:
+   gotosocial [global options] command [command options] [arguments...]
+
+VERSION:
+   0.1.0-SNAPSHOT a940a52
+
+COMMANDS:
+   server   gotosocial server-related tasks
+   admin    gotosocial admin-related tasks
+   testrig  gotosocial testrig tasks
+   help, h  Shows a list of commands or help for one command
+
+GLOBAL OPTIONS:
+   [a huge list of global options -- too much to show here]
+```
+
+Under `COMMANDS`, you can see the standard `server` command. But there are also commands doing admin and testing etc, which will be explained in this document.
+
+**Please note -- for all of these commands, you will still need to set the global options correctly so that the CLI tool knows how eg., how to connect to your database, which database to use, which host and account domain to use etc.**
+
+You can set these global options using environment variables, passing them as CLI variables after the `gotosocial` part of the command (eg., `gotosocial --host example.org [commands]`), or by just pointing the CLI tool towards your config file (eg., `gotosocial --config-path ./config.yaml [commands]`).
