+If needed, an alternative `config` path can be used by using the `FRIENDICA_CONFIG_DIR` environment variable (full path required!).
+This is useful in case of hardening the system by separating configuration from program binaries.
+
+### Static Configuration location
+
+The `static` directory holds the codebase default configurations files.
+They must not be changed by users, because they can get changed from release to release.
+
+Currently, the following configurations are included:
+- `defaults.config.php` holds the default values for all the configuration keys that can only be set in `local.config.php`.
+- `settings.config.php` holds the default values for some configuration keys that are set through the admin settings page.
