+# MDK Crate Integration
+
+## Overview
+
+Whitenoise uses the `mdk-core` crate for MLS protocol implementation. This document details the integration patterns and usage within our project.
+
+## Dependencies
+
+From `Cargo.toml`:
+```toml
+mdk-core = { version = "0.5.0", git="https://github.com/parres-hq/mdk" }
+mdk-sqlite-storage = { version = "0.5.0", git="https://github.com/parres-hq/mdk" }
+```
+
+## Core Integration Points
+
+### MDK Initialization
+
+The `mdk` instance is created per account:
+
+```rust
+// From src/whitenoise/accounts.rs
+let mdk = Account::create_mdk(account.pubkey, &self.config.data_dir)?;
+```
+
+### Message Processing
+
+MLS messages are processed through the nostr-mls interface:
+
+```rust
+// From src/whitenoise/event_processor/event_handlers/handle_mls_message.rs
+match mdk.process_message(&event) {
+    Ok(result) => {
+        // Handle successful processing
+    }
+    Err(e) => {
+        // Handle MLS errors
+        Err(WhitenoiseError::MdkCoreError(e))
+    }
+}
+```
+
+### Storage Backend
+
+We use SQLite storage for MLS state persistence:
+- Database location: `{data_dir}/mls/`
+- Per-account storage isolation
+- Integrated with main application database
+
+### Key Package Management
+
+Key packages are generated and managed through the mdk interface:
+
+```rust
+// Key package generation for group joining
+let key_package = mdk.generate_key_package()?;
+```
+
+### Group Operations
+
+Core group operations available:
+
+1. **Create Group**: `mdk.create_group()`
+2. **Join Group**: `mdk.join_group(welcome_message)`
+3. **Add Member**: `mdk.add_member(key_package)`
+4. **Remove Member**: `mdk.remove_member(member_id)`
+5. **Send Message**: `mdk.send_message(content)`
+
+### Error Handling
+
+MLS errors are wrapped in our custom error type:
+
+```rust
+#[derive(Debug, thiserror::Error)]
+pub enum WhitenoiseError {
+    #[error("MDK error: {0}")]
+    MdkCoreError(#[from] mdk_core::Error),
+    // ... other error types
+}
+```
+
+## Configuration
+
+### MLS Provider Configuration
+
+The mdk crate is configured with:
+- Crypto provider: Default MLS crypto implementation
+- Storage provider: SQLite backend
+- Transport: Nostr event system
