+## Using the command-line interface
+
+The command-line interface of Mastodon is an executable file called `tootctl` residing in the `bin` directory within the Mastodon root directory. You must specify which environment you intend to use whenever you execute it by specifying the `RAILS_ENV` environment variable. Unless you are a developer working on a local machine, you need to use `RAILS_ENV=production`. If you are sure that you will never need another environment (for development, testing, or staging), you can add it to your `.bashrc` file for convenience, e.g.:
+
+```bash
+echo "export RAILS_ENV=production" >> ~/.bashrc
+```
+
+If so, you won't need to specify it each time inline. Otherwise, calls to `tootctl` will usually go like this, assuming that the Mastodon code is checked out in `/home/mastodon/live`:
+
+```bash
+cd /home/mastodon/live
+RAILS_ENV=production bin/tootctl help
+```
