+# Getting Started with the Database Migration Assessment (DMA) Collector
+
+These instructions will guide you through setting up and running the DMA collector using the Python CLI.
+
+## Verify Python Version
+
+The DMA collector requires Python 3.9 or higher. Check your Python version by opening a terminal and running:
+
+```bash
+python3 --version
+```
+
+If your Python version is lower than 3.9, you'll need to install a compatible version.
+
+## Create a Virtual Environment (Recommended)
+
+A virtual environment isolates the DMA collector's dependencies from other Python projects. This prevents conflicts and ensures a consistent environment.
+
+### Create the virtual environment
+
+To create the new virtual environment.
+
+```bash
+python3 -m venv .venv
+```
+
+Activate the virtual environment by running:
+
+```bash
+source .venv/bin/activate
+```
+
+(You'll typically see the virtual environment name in parentheses at the beginning of your terminal prompt: `(.venv) $`)
+
+## Install the DMA Readiness Check Utility
+
+Navigate to the directory containing the DMA collector wheel file (.whl file). This file is the packaged distribution of the collector.
+
+Install the wheel file using pip:
+
+```shell
+pip install dma-collector-<version>.whl
+```
+
+**Note** Replace `<version>` with the actual version number of the wheel file (e.g., dma-collector-1.2.3.whl).
+
+## Executing the Postgres Readiness Check
+
+Now that the DMA collector is installed, you can run the readiness check for Postgres.
+
+```shell
+dma readiness-check --db-type postgres --hostname localhost --no-prompt --port 5432 --database postgres --username postgres --password password1
+```
+
+If you do not supply credentials at the CLI, the tool will prompt you for connection information.
