 ## Steps to install and configure the development environment under the Linux (Ubuntu) distribution
 
 ### Java: OpenJDK 17
+
 ```
 	$ sudo apt install openjdk-17-jre-headless
 ```
 
 ### Build tool: Maven
+
 ```
 	$ sudo apt install maven
 ```
 
 ### DB: PostgreSQL/PgAdmin4 (Management tool for PostgreSQL)
+
 #### PostgreSQL:
+
 ```
 	$ sudo apt install -y postgresql-common -y
 ```
+
 ```
 	$ sudo /usr/share/postgresql-common/pgdg/apt.postgresql.org.sh (Press Enter when prompted.)
 ```
+
 ```
  	$ sudo apt install -y postgresql
 ```
+
 ```
 	$ sudo systemctl restart postgresql
 ```
+
 ```
 	$ sudo systemctl status postgresql
 ```
+
 ```
     	$ sudo -u postgres psql
 ```
+
 ```
         postgres=#  ALTER USER postgres WITH ENCRYPTED PASSWORD '<password>';
 ```
+
 ```
 	postgres=#  CREATE USER db_manager ENCRYPTED PASSWORD '<password>';
 ```
+
 ```
 	postgres=#  \q
 ```
+
 ```
    	$ sudo sed -i '/^local/s/peer/scram-sha-256/' /etc/postgresql/17/main/pg_hba.conf
 ```
+
 ```
    	$ sudo systemctl restart postgresql
 ```
 
 #### PgAdmin4:
+
 ```
 	$ sudo apt install pgadmin4-desktop
 ```
 
 #### DB Setup:
+
 - Open PgAdmin4
 - Create a new database and add the user (//Example: Database: “regAppDev” and the Owner: “regapp-dev”)
 - Create new user in Login/Group Roles and assign assign required permissions (//Example: Name: regapp-dev and set Privileges: Can login? Yes)
 
 #### Inject the existing “regApp” DB to the Postgresql:
+
 - Download the `regapp_dev.sql` file from [bws&s](https://bwsyncandshare.kit.edu/apps/files/files/4223252485?dir=/regApp_setup)
+
 ```
        $ psql --username=<db_user_name> databasename < data_base_dump.sql
 ```
-- Edit the file `/etc/postgresql/17/main/postgresql.conf` file and set `max_prepared_transactions` to `32`, instead of 0. //On the production system it is set to 128.
