-### About Object Deletions
+### Object Deletions
 
 Yep, we highly recommend you use **Soft Deletions**. That's why we add a `isDeleted` property to CKRecordConvertible protocol. 
 
 When you want to delete a object, you just need to set its `isDeleted` property to true. And the rest of things are already taken care of.
 
 *You also don't need to worry about the clean-up things. It has also been considered.*
 
+### How about syncing asset? 
+Luckily, we have a perfect solution for syncing asset. 
+Absolutely, you could also store your image or kind of resource stuff as `Data` type and everything works fine. But Realm has a [16MB limit]() of data property. And CloudKit encourages us to use `CKAsset` in places where the data you want to assign to a field is more than a few kilobytes in size.
+So taking the consideration of the above two, we recommend you to use `CreamAsset` property to hold data. `CreamAsset` will store local data on the file system and just save file paths in the Realm, all automatically. And we'll wrap things up to upload to CloudKit as `CKAsset`.
