 Add DataLoader to graphql-composer resolvers.
 
+### Deprecation reason
+
+DataLoader cannot be expressed like a simple plugin. Mostly this plugin was used with [graphql-compose-mongoose](https://github.com/graphql-compose/graphql-compose-mongoose) models. From graphql-compose-mongoose@9.0.0 ([read more](https://github.com/graphql-compose/graphql-compose-mongoose/blob/master/docs/releases/9.0.0.md#added-new-dataloader--dataloadermany-resolvers)) it starts provide new built-in resolvers `dataLoader` & `dataLoaderMany resolvers` which implement DataLoader logic in different manner.
+
 ### Installation
 ```
 npm install graphql-compose-dataloader --save
