+  },
+  onSubmit: async (values) => {
+    await sendEmail(values);
+    form.reset();
+  },
+});
+
+return (
+  <form {...form.getFormProps()}>
+    <FormField name="name" label="Name" required {...form.getFieldProps('name')} />
+    <FormField type="email" name="email" label="Email" required {...form.getFieldProps('email')} />
+    <FormField type="textarea" name="message" label="Message" required {...form.getFieldProps('message')} />
+    <Button type="submit" disabled={!form.isValid} loading={form.isSubmitting}>
+      Send
+    </Button>
+  </form>
+);
+```
+
+### Registration Form
+```tsx
+const form = useForm({
+  initialValues: {
+    firstName: '',
+    lastName: '',
+    email: '',
+    password: '',
+    confirmPassword: '',
+    terms: false,
+  },
+  validationRules: {
+    firstName: { required: true, minLength: { value: 2 } },
+    lastName: { required: true, minLength: { value: 2 } },
+    email: { required: true, email: true },
+    password: { 
+      required: true, 
+      minLength: { value: 8 },
+      pattern: { value: /^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)/ }
+    },
+    confirmPassword: { 
+      required: true, 
+      custom: (value) => value === form.values.password ? null : 'Passwords do not match'
+    },
+    terms: { 
+      required: 'You must accept terms',
+      custom: (value) => value ? null : 'Required'
+    },
+  },
+  onSubmit: async (values) => {
+    await registerUser(values);
+    alert('Registered!');
+  },
+});
+```
+
+### Search and Filter
+```tsx
+const form = useForm({
+  initialValues: { search: '', category: '', status: '' },
+  validationRules: {},
+  onSubmit: async (values) => {
+    await performSearch(values);
+  },
+});
+
+return (
+  <form {...form.getFormProps()}>
+    <FormField
+      type="text"
+      name="search"
+      placeholder="Search..."
+      showClear
+      {...form.getFieldProps('search')}
+    />
+    <FormField
+      type="select"
+      name="category"
+      options={categoryOptions}
+      {...form.getFieldProps('category')}
+    />
+    <Button type="submit">Search</Button>
+  </form>
+);
+```
+
+## 🎨 Design System Integration
+
+### Colors
+- Primary: `--color-primary`
+- Danger: `--color-danger`
+- Success: `--color-success`
+- Neutral: `--color-neutral-dark`, `--color-neutral-light`
+
+### Spacing

+## 🔄 Migration Path
+
+### From Legacy Forms
+```tsx
+// Old
+<input 
+  value={email}
+  onChange={e => setEmail(e.target.value)}
+  className={error ? 'error' : ''}
+/>
+
+// New
+<FormField
+  type="email"
+  name="email"
+  value={form.values.email}
+  error={form.errors.email?.[0]}
+  onChange={(e) => form.setFieldValue('email', e.target.value)}
+/>
+```
+
+### From Manual Validation
+```tsx
+// Old
+const validate = () => {
+  const errors = {};
+  if (!email) errors.email = 'Required';
+  return errors;
+}
+
+// New
+const form = useForm({
+  validationRules: {
+    email: { required: true, email: true }
+  }
+});
+```
+
+## 🎯 Next Steps
+
+1. **Integration**: Replace existing ContactForm with new system
+2. **Testing**: Add unit tests for all components
+3. **Documentation**: Add JSDoc comments
+4. **Examples**: Create more real-world examples
+5. **Performance**: Add memoization where needed
+6. **i18n**: Integrate with translation system
