+# Setting up a PostgreSQL RDS with CDK in Python
+
+### Create a virtual environment and install dependencies:
+
+```
+virtualenv .env
+source .env/bin/activate
+pip3 install -r requirements.txt
+```
+
+### Define You RDS DB 
+
+Add any constant variable in `cdk.json` and then define how you want your RDS instance in `postgre_sql_example/postgre_sql_example_stack.py`:
+
+```
+class PostgreSqlExampleStack(core.Stack):
+
+    def __init__(self, scope: core.Construct, id: str, **kwargs) -> None:
+        super().__init__(scope, id, **kwargs)
+
+        # Database Instance
+        instance = rds.DatabaseInstance(self,
+            'examplepostgresdbinstance', 
+            master_username=master_username,
+            engine=rds.DatabaseInstanceEngine.POSTGRES, instance_class=ec2.InstanceType.of(ec2.InstanceClass.BURSTABLE2, ec2.InstanceSize.MICRO), 
+            vpc=self.vpc,
+            auto_minor_version_upgrade=auto_minor_version_upgrade,
+            availability_zone=availability_zone,
+            database_name=database_name,

+            backup_retention=backup_retention,
+            monitoring_interval=monitoring_interval,
+         )
+```
+
+### Create synthesized CloudFormation templates
+
+```
+cdk synth
+```
+
+You can check what changes are introduced into your current AWS resources with:
+```
+cdk diff --profile <AWS PROFILE>
+```
+
+
+### Deploy to AWS
+
+If everything looks OK, deploy with:
+
+```
+cdk deploy --profile <AWS PROFILE>
+```
+
+To check all the stacks in the app:
+
+```
+cdk ls
+```
+
+### Clean up
+
+To destroy/remove all the newly created resources, run:
+
+```
+cdk destroy --profile <AWS PROFILE>
+```
