-![Hasura GraphQL Engine Banner](assets/banner.png)
+Hasura GraphQL Engine is a blazing-fast GraphQL server that gives you **instant GraphQL APIs over Postgres**. Hasura helps you build GraphQL apps backed by Postgres or incrementally move to GraphQL for existing applications using Postgres.
 
-Hasura GraphQL Engine is a performant GraphQL server that provides **ready-to-use GraphQL API over Postgres** by auto-generating GraphQL schema and corresponding resolvers. 
+------------------
 
-* **Make powerful queries**: built-in filtering, pagination, and pattern search arguments and operators
-* **Works with existing database**: point it to an existing Postgres database to instantly get a ready-to-use GraphQL API
-* **Fine-grained access control**: dynamic access control that integrates with your Auth
-* **Light-weight & performant**: ~15MB docker image; ~50MB RAM @ 1000 req/s; multi-core aware
-* **Dev friendly**: admin UI & Rails-inspired schema migrations

+* **Works with existing, live databases**: Point it to an existing Postgres database to instantly get a ready-to-use GraphQL API
+* **Fine-grained access control**: Dynamic access control that integrates with your auth system (eg: auth0, firebase-auth)
+* **High-performance & low-footprint**: ~15MB docker image; ~50MB RAM @ 1000 req/s; multi-core aware
+* **Admin UI & Migrations**: Admin UI & Rails-inspired schema migrations
 * **Postgres** ❤️: supports Postgres types (PostGIS/geo-location, etc.), turns views to *graphs*, trigger stored functions or procedures with mutations

 ## Architecture
 
-The Hasura GraphQL Engine fronts a Postgres database instance and can serve as an API Gateway for all data requests from client apps. It can be configured to work with your existing Auth middleware to handle access control to data using field-level rules with dynamic variables.
-
-The GraphQL Engine is a standalone, multi-core aware component that can be scaled vertically and horizontally.

 You can also place the engine behind a central GraphQL proxy that fronts multiple GraphQL APIs via schema stitching.

 ## Client-side tooling
 
-GraphQL Engine provides an HTTP API. This means you can use any client-side tool or library to query the endpoint. To fully leverage GraphQL, it is recommended that you use GraphQL specific client-side tooling like [Apollo Client](https://github.com/apollographql/apollo-client), [Relay](https://github.com/facebook/relay), etc. See [awesome-graphql](https://github.com/chentsulin/awesome-graphql) for a list of such tools.
+Hasura works with any GraphQL client. We recommend using [Apollo Client](https://github.com/apollographql/apollo-client). See [awesome-graphql](https://github.com/chentsulin/awesome-graphql) for a list of clients.
