-# GiraphQL SchemaBuilder
+## GiraphQL - A plugin based GraphQL schema builder for typescript
 
-GiraphQL is library for creating GraphQL schemas in typescript using a strongly typed code first
-approach. The GiraphQL schema builder makes writing schemas easy by providing a simple clean API
-with helpful auto-completes, and removing the need for compile steps or defining the same types in
-multiple files.
+GiraphQL makes writing graphql schemas in typescript easy, fast and enjoyable. The core of GiraphQL
+adds 0 overhead at runtime, and has `graphql` as its only dependency.
+
+By leaning heavily on typescripts ability to infer types, GiraphQL is the most type-safe way of
+writing GraphQL schemas in typescript/node while requiring very few manual type definitions and no
+code generation.
+
+GiraphQL has a unique and powerful plugin system that makes every plugin feel like its features are
+built into the core library. Plugins can extend almost any part of the API by adding new options or
+methods that can take full advantage of GiraphQLs type system.
