+Configuration is done primarily through the [environment](https://git.tt-rss.org/fox/ttrss-docker-compose/wiki#how-do-i-set-global-configuration-options). Copy ``.env-dist`` to ``.env`` and edit any relevant variables you need changed.
 
 You will likely have to change ``TTRSS_SELF_URL_PATH`` which should equal fully qualified tt-rss
 URL as seen when opening it in your web browser. If this field is set incorrectly, you will
 likely see the correct value in the tt-rss fatal error message.
 
+Legacy configuration file (`config.php`) is not created automatically, if you need it, copy it from `config.php-dist` manually.

 By default, frontend container binds to `localhost` port `8280`. If you want the container to be
 accessible on the net, without using a reverse proxy sharing same host, you will need to
 remove ``127.0.0.1:`` from ``HTTP_PORT`` variable in ``.env``.
 
 Please don't rename the services inside `docker-compose.yml` unless you know what you're doing. Web container expects application container to be named `app`, if you rename it and it's not accessible via Docker DNS as `http://app` you will run into 502 errors on startup.
 
-Main configuration file (`config.php`) is rewritten on startup, don't edit it manually. Use [environment variables](https://git.tt-rss.org/fox/ttrss-docker-compose/wiki#how-do-i-set-global-configuration-options) or `config.d` snippets to customize it.
