+
+## What is PostgreSQL?
+
+---
+
+PostgreSQL, often simply "Postgres", is an object-relational database management system (ORDBMS) with an emphasis on extensibility and standards-compliance. It can handle workloads ranging from small single-machine applications to large Internet-facing applications with many concurrent users. Recent versions also provide replication of the database itself for security and scalability.
+
+## Features
+
+---
+
+- User-defined types.
+- Table inheritance.
+- Sophisticated locking mechanism.
+- Foreign key referential integrity.
+- Views, rules, subquery.
+- Nested transactions (savepoints)
+- Multi-version concurrency control (MVCC)
+- Asynchronous replication.
+
+## Installation
+
+---
+
+1. Select the devices to which PostgreSQL will be installed from 'Devices' page.
+
+2. Navigate to the 'App Marketplace' tab and select the 'PostgreSQL' application.
+
+3. The 'Install Now' button should now appear near the top of the screen. Select this button.
+
+4. Give your installation a name and fill all the parameters. Click 'Install PostgrSQL' in the bottom right corner.
+
+## Required Parameters
+
+---
+
+**POSTGRES_USERNAME**
+This variable is used in conjunction with `POSTGRES_PASSWORD` to set a user and its password.
+
+**POSTGRES_PASSWORD**
+This variable is used in conjunction with `POSTGRES_USERNAME` to set a user and its password.
+
+## Additional Parameters
+
+---
+
+**Installation Name**
+
+Here you will put your app name. Although the app name is MariaDB on the portal, you can personalize the name that is shown on the device's Applications.
+
+**NAMESPACE_NAME**
+This variable is used to create a namespace in Kubernetes. Leave it in blank to install pods on default namespace.
+
+## Using PostgreSQL
+
+---
+
+Use device shell to execute commands using psql client. This command will open psql client in interactive mode.
+
+kubectl exec -it -n <yournamespace> postgres-0 -- psql -U <yourusername> -W
+
+After executing this command, you will be asked for the password you already assign in the Postgres installation.
+
+Then, you can execute psql commands to use the database.
+
+## OS Architectures
+
+---
+
+- Arm64
+
+## Limitations / Known issues
+
+---
+
+## PostgreSQL Platform Video
