+
+_Last updated: 2026-01-16_
+
+## 1. Overview
+The FSTEC BDU connector ingests the Russian BDU vulnerability database and maps entries to canonical IDs.
+
+## 2. Authentication
+- No authentication required for public feeds unless a regional mirror enforces access controls.
+
+## 3. Configuration (`concelier.yaml`)
+```yaml
+concelier:
+  sources:
+    fstec-bdu:
+      baseUri: "<fstec-bdu-feed-base>"
+      maxDocumentsPerFetch: 20
+      fetchTimeout: "00:00:45"
+      requestDelay: "00:00:00"
+```
+
+## 4. Offline and air-gapped deployments
+- Mirror BDU data into the Offline Kit and repoint `baseUri` to the mirror.
+
+## 5. Common failure modes
+- Regional mirror availability.
+- Non-standard identifier formats.
