+# Helium archive-node deployment
+
+This directory contains the non-secret manifests for the dedicated helium
+archive node. Install the files into these separate compose projects:
+
+- `~/Repositories/compose/qbittorrent-helium/compose.yaml`
+- `~/Repositories/compose/syncthing-helium/compose.yaml`
+- `~/Repositories/compose/ArchiveControl-archive/{compose.yaml,client.toml}`
+
+The qBittorrent API and Syncthing GUI/API bind only to loopback. Syncthing
+transport/discovery ports are published normally. qBittorrent data and
+Syncthing route folders both live under `/media/Data2`; the Archive Control
+container therefore mounts `/media/Data2` once at `/data/storage` so archive
+placements can hardlink rather than make a full copy.
+
+`/media/Data2/Downloading` already contains unrelated files. The fresh qB
+instance must not import or manage them; only Archive Control-created torrents
+are managed.
