 You can also generate new projects with igniter preinstalled, and run installers in the same command.
 
+First, install the archive:
+
+```elixir
+mix archive.install hex igniter_new

+
+Then you can run `mix igniter.new`
+
 ```
 mix igniter.new app_name --install ash
 ```
 
-To use this command, install the archive:
+Or if you want to use a different project creator, specify the mix task name with the `--with` flag. Any arguments will be passed through to that task, with the exception of `--install` and `--example`.

-mix archive.install hex igniter_new

+mix igniter.new app_name --install ash --with phx.new --no-ecto
