+# Creating Claude Matrix User
+
+Since Matrix registration is disabled, you'll need to create the Claude user manually using admin tools.
+
+## Option 1: Synapse Admin Panel
+
+1. **Access Synapse Admin**: https://synapse.klas.chat/admin
+2. **Login with admin credentials**

+   - **Password**: `claude_assistant_2025`
+   - **Display Name**: `Claude Assistant`
+   - **Admin**: `No`
+
+## Option 2: Command Line (if you have access to Synapse container)
+
+```bash
+# Access synapse container
+docker exec -it synapse /bin/bash
+
+# Create user using register_new_matrix_user
+register_new_matrix_user -u claude -p claude_assistant_2025 -c /data/homeserver.yaml https://matrix.klas.chat
+```
+
+## Option 3: Database Direct (if needed)
+
+```sql
+-- Connect to Matrix database and insert user manually
+-- This requires knowledge of your Matrix database structure
+```
