 ## Data and Config Files
 
-Default host paths:
+Persistence paths depend on how ScanSlicer is run.
+
+Non-container runs (`uv run scanslicer`, `python -m scanslicer`):
 
 - Defaults: `~/.config/scanslicer/defaults.json`
 - Named presets: `~/.config/scanslicer/presets.json`
 - Auto-tune feedback: `~/.config/scanslicer/autotune-feedback.json`
 - Session status log: `~/.config/scanslicer/status.log`
 
-Container behavior:
+If `XDG_CONFIG_HOME` is set, these are stored under `$XDG_CONFIG_HOME/scanslicer/` instead.
+
+Container runs:
 
 - When running in container and `/work` exists, these are stored under `/work/.scanslicer/`.
+- In the provided `docker-compose.yml`, the current repository is mounted as `/work`, so these files appear in `.scanslicer/` inside the project directory on the host.
