+# Polkadot SDK Issue Tracking
+
+Bu dosya, pezkuwi-sdk kodunda referans verilen Polkadot SDK issue'larını listeler.
+Her biri için kendi repomuzda bir tracking issue açılmalı.
+
+## Workflow
+
+1. Her Polkadot SDK issue için `pezkuwichain/pezkuwi-sdk` reposunda yeni issue aç
+2. Issue açıklaması: "Track Polkadot SDK issue #XXX"
+3. Bot haftalık olarak Polkadot'u tarar ve issue durumlarını günceller
+4. Discord'a bildirim gönderilir
+
+## Toplu Issue Oluşturma Scripti
+
+```bash
+# GitHub CLI ile toplu issue oluşturma örneği
+for issue_num in 2 3 4 5 7 8 10 11 12 ...; do
+  gh issue create \
+    --repo pezkuwichain/pezkuwi-sdk \
+    --title "Track Polkadot SDK #$issue_num" \
+    --body "This issue tracks upstream changes in https://github.com/paritytech/polkadot-sdk/issues/$issue_num"
+done
+```
