-# Import
+# Legacy Migration
 
 This guide helps you to import data from our legacy servers, which are using FeathersJS and MongoDB.
 
+**You can skip this if you don't plan to migrate any legacy applications!**
+
 ## Prerequisites
 
 You need [docker](https://www.docker.com/) installed on your machine. Furthermore you need SSH access to the server and you need to know the following login credentials and server settings:

-GraphQL is a data query language which provides an alternative to REST and ad-hoc web service architectures. It allows clients to define the structure of the data required, and exactly the same structure of the data is returned from the server.

-## Seeding The Database

-Optionally you can seed the GraphQL service by executing mutations that will write sample data to the database:

 GraphQL Middleware uses the [_middleware pattern_](https://dzone.com/articles/understanding-middleware-pattern-in-expressjs) \(well-known from Express.js\) to pull out repetitive code from resolvers and execute it before or after one of your resolvers is invoked. This improves code modularity and keeps your resolvers clean and simple.
