   already setup, but you'd need to setup SOLR (when using fulltext
   search) and install some programs for the joex component. This
   applies to the `zip` and `deb` files. The files can be downloaded

+Every [component](@/docs/intro/_index.md#components) (restserver, joex,
 consumedir) can run on different machines and multiple times. Most of
 the time running all on one machine is sufficient and also for
 simplicity, the docker-compose setup reflects this variant.
+
+While there are many different ways to run docspell, at some point all
+call docspell binaries. These accept one argument: a [config
+file](@/docs/configure/_index.md). If this is not given, the default
+is used, which gets you started on a single machine, but it is very
+likely you want to change these to match your use-case/setup.

+{% infobubble(mode="info", title="⚠ Please note") %}
+
+Please have a look at the [configuration
+page](@/docs/configure/_index.md) page, before making docspell
+publicly available. By default, everyone can create an account. This
+is great for trying out and using it in an internal network. But when
+opened up to the outside, it is recommended to lock this down.
