 Demo mode adds its own set of env vars (per-session vaults, auto-cleanup, proxy allowlist, login blocking). See [`examples/demo/`](examples/demo/) if you want to run a public demo deployment.
 
+## Offline / restricted-network install
+
+If the container can't reach GitHub on first run (air-gapped or restricted networks), download Obsidian yourself from [obsidian.md](https://obsidian.md/download) (the `.deb`), mount it into the container, and point `OBSIDIAN_PACKAGE` at it:
+
+```yaml
+    volumes:
+      - ./obsidian_1.12.7_amd64.deb:/packages/obsidian.deb:ro
+    environment:
+      - OBSIDIAN_PACKAGE=/packages/obsidian.deb
+```
+
+On first run the entrypoint unpacks that instead of downloading. Match the version this release pins (see the OCI label and CHANGELOG); a mismatch logs a warning and still boots. `.asar.gz` and `.asar` are also accepted.
+
 ## Migrating an existing vault
 
 Each subdirectory of `/vaults` is treated as a separate vault, so dropping in an existing Obsidian vault directory will make it available in Ignis.
