 Follow the steps to start the application:
 
 ## Clone
+
 - First, clone the repository:
 
-   ```bash
-   git clone https://github.com/keploy/samples-java
-   ```
+  ```bash
+  git clone https://github.com/keploy/samples-java
+  ```
+
   Navigate to the project folder:
 
-   ```bash
-   cd samples-java/spring-boot-postgres-graphql
-   ```
+  ```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
+
+You have two possible cases:
+
+### Use your postgres installation
+
+If you already have PostgreSQL installed on your machine and want to use this installation, follow these steps:
+
+1. If not already started, launch the PostgreSQL service:
+
    ```bash
-   curl -O https://raw.githubusercontent.com/keploy/keploy/main/keploy.sh && source keploy.sh
+   sudo service postgresql start
    ```
 
-## Setup DB
+2. Set the password for the postgres user (or alternatively, modify the application.properties file within the project):
+   ```bash
+   sudo -u postgres psql -c "ALTER USER postgres WITH PASSWORD 'root';"
+   ```
+3. Create the demo database:
+
+   ```bash
+   sudo -u postgres createdb library_demo
+   ```
 
 ### 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
-    ```
-   
+   ```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
-    ```
+   ```bash
+      docker run -d -p 5432:5432 --name postgres postgres_library:demo

 ### 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 {

-           }
-         }
-      ```

-               lastName 
-            }
-         }
-      ```
-
-   -  Make a `getAuthorById` query:

-               firstName
-            }
-         }
-      ```

 ### 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.
