+## TypeScript Support

+Tenancy now includes TypeScript type definitions. Example usage:
+
+```typescript
+import {config, TenantSchema, db} from 'node-tenancy';
+import {Schema} from 'mongoose';
+
+// Define schemas with TypeScript types
+interface User {
+    username: string;
+    email: string;
+    active: boolean;
+    createdAt: Date;
+}
+
+const userSchema = new Schema<User>({
+    username: String,
+    email: {type: String, required: true},
+    active: {type: Boolean, default: true},
+    createdAt: {type: Date, default: Date.now}
+});
+
+// Configure tenancy
+config.setConfig({
