+# NestJS Prisma Graphql CRUD Generater
+
+Generate CRUD resolvers from GraphQL schema with NestJS and Prisma
+
+# Getting Started
+
+1. Install this package in your project using:
+
+```shell
+yarn add nestjs-prisma-graphql-crud-gen
+```
+
+2. Add the generator to the schema.prisma:
+
+```
+generator custom_generator {
+  provider = "nestjs-prisma-graphql-crud-gen"
+  output = "../generated"
+}
+```
+
+3. Run the generator
+
+```shell
+npx prisma generate
+```
+
+# Output Directory Structure
+
+```
