 5. **Query parameters**: Matches Wavelog's LoTW download
 
+### DOK Fields (DARC Ortsverband Kennung)
+
+The QSO table includes DOK fields for German amateur radio awards:
+- **myDarcDok**: User's own DOK (e.g., 'F03', 'P30', 'G13')
+- **darcDok**: QSO partner's DOK
+
+DOKs are local club identifiers used by DARC (German amateur radio club) for award tracking.
+These fields are populated when syncing from LoTW if the ADIF data contains MY_DARC_DOK and DARC_DOK tags.
+
+### DCL Preparation
+
+The application is prepared for future DARC Community Logbook (DCL) integration:
+
+**Infrastructure in place:**
+- Database schema includes DCL confirmation fields (`dcl_qsl_rdate`, `dcl_qsl_rstatus`)
+- Backend service stub (`src/backend/services/dcl.service.js`) with TODO comments for implementation
+- Settings page includes DCL API key input
+- QSO table displays DCL confirmations alongside LoTW
+
+**Current status:**
+- DCL does not provide a public download API (as of 2025)
+- Manual ADIF export is available at https://dcl.darc.de/dml/export_adif_form.php
+- When DCL adds an API endpoint, the existing infrastructure can be easily activated
+
+**Future implementation steps (when DCL API is available):**
+1. Implement `fetchQSOsFromDCL()` in `dcl.service.js`
+2. Add ADIF parser for DCL format
+3. Implement `syncQSOs()` to store DCL confirmations
+4. Add sync endpoint similar to LoTW
+
+### Confirmation Display
+
+The QSO table shows confirmations from multiple services:
+- Each service is listed with its name (LoTW, DCL) and confirmation date
+- Multiple confirmations per QSO are supported
+- Empty state shows "-" when no confirmations exist
+- Service types are color-coded and formatted for easy scanning
+
 ### Pagination
 
 - Default page size: 100 QSOs per page
