+# Library DEMO
+
+### Requirements
+
+- JDK 17
+- Maven 3.9.5
+- Docker or PostgreSQL
+
+### About the DEMO
+
+This is a Spring Boot application implementing a GraphQL service to handle requests related to books and authors.
+
+The controller provides four queries:
+
+- `getBookByName`: Returns a book based on the specified name.
+- `getAllBooks`: Retrieves all books present in the repository.
+- `getAuthorById`: Fetches an author based on the provided ID.
+- `getAllAuthors`: Retrieves all authors available in the repository.
+
+# Getting Started
+
+Follow the steps to start the application:
+
+## Clone
+- First, clone the repository:
+
+   ```bash
+   git clone https://github.com/keploy/samples-java
+   ```
+  Navigate to the project folder:
+
+   ```bash
+   cd samples-java/spring-boot-postgres-graphql
+   ```
+
+## Quick Keploy Installation
+
+- Depending on your OS and preference (Docker/Native), you can set up Keploy using the one-click installation method:
+   ```bash
+   curl -O https://raw.githubusercontent.com/keploy/keploy/main/keploy.sh && source keploy.sh
+   ```
+
+## Setup DB
+
+### Use postgres docker image
+
+If you have Docker installed and prefer a PostgreSQL instance in a container, follow these steps:
+1. Build the Docker image:
+
+    ```bash
+       docker build -t postgres_library:demo ./postgres_demo_docker
+    ```
+   
+2. Run a container from the generated image:
+
+    ```bash
+       docker run -d -p 5432:5432 --name postgres postgres_library:demo
+    ```
+
+## Use of Keploy
+
+1. Your application is ready to be executed!!
+   To start Keploy in record mode, in the root directory, run:
+
+   ```bash
+   keploy record -c "mvn spring-boot:run"
+   ```
+
+### Query from GraphQL GUI
+
+Now, go to `localhost:8081/graphiql` and access the GraphQL interface to make requests to the application.
+   - Make a `getAllBooks` query:
+
+      ```graphql
+         query {
+           getAllBooks {
+               name
+               author {
+                  id
+                  firstName
+                  lastName
+               }
+           }
+         }
+      ```
+
+   -  Make a `getBookByName` query:
+
+      ```graphql
+         query {
+           getBookByName(name: "The Secret of the Moon") {
+               id
+               name
+               pageCount
+               author {
+                  firstName
+                  lastName
+               }
+           }
+         }
+      ```
+
+   -  Make a `getAllAuthors` query:
+
+      ```graphql
+         query {
+            getAllAuthors {
+               id
+               firstName
+               lastName 
+            }
+         }
+      ```
+
+   -  Make a `getAuthorById` query:
+
+      ```graphql
+         query {
+            getAuthorById(id: 2) {
+               firstName
+            }
+         }
+      ```
+
+You can experiment with the data you want to retrieve from the query by removing or rearranging fields.
+
+   The generated tests and mocks are stored in the `Keploy` directory in the current working directory.
+
+
+### Execute tests
+
+To test the app, start Keploy in test mode. In the root directory, run:
+
+   ```bash
+      keploy test -c "mvn spring-boot:run" --delay 15
+   ```
+
+   This will run the tests and generate the report in the `Keploy/reports` directory in the current working directory.
