+# Bundled Legacy Data
+
+This directory contains the legacy SQLite databases used by the Django import command:
+
+- `cincin_phase1.sqlite`
+- `dalcorso.sqlite`
+
+The defaults in [`backend/config/settings.py`](../../backend/config/settings.py) point here so the `django-port` subtree can be used without depending on workspace-root copies of those files.
+
+If needed, the importer can still be redirected with:
+
+- `LEGACY_CINCIN_DB`
+- `LEGACY_DALCORSO_DB`
