+### DAB Demo
+
+## Overview
+This demo showcases how to use Databricks Asset Bundles (DABs) with DLT-Meta:
+
+This demo will perform following steps:
+- Create dlt-meta schema's for dataflowspec and bronze/silver layer
+- Upload necessary resources to unity catalog volume
+- Create DAB files with catalog, schema, file locations populated
+- Deploy DAB to databricks workspace
+- Run onboarding using DAB commands
+- Run Bronze/Silver Pipelines using DAB commands
+- Demo examples will showcase fan-out pattern in silver layer
+- Demo example will show case custom transformations for bronze/silver layers
+- Adding custom columns and metadata to Bronze tables
+- Implementing SCD Type 1 to Silver tables
+- Applying expectations to filter data in Silver tables
+
+### Steps:
+1. Launch Command Prompt
+
+2. Install [Databricks CLI](https://docs.databricks.com/dev-tools/cli/index.html)
+    - Once you install Databricks CLI, authenticate your current machine to a Databricks Workspace:
+
+    ```commandline
+    databricks auth login --host WORKSPACE_HOST
+    ```
+
+3. Install Python package requirements:
+    ```commandline
+    # Core requirements
+    pip install "PyYAML>=6.0" setuptools databricks-sdk
+
+    # Development requirements
+    pip install flake8==6.0 delta-spark==3.0.0 pytest>=7.0.0 coverage>=7.0.0 pyspark==3.5.5
+    ```
+
+4. Clone dlt-meta:
+    ```commandline
+    git clone https://github.com/databrickslabs/dlt-meta.git 
+    ```
+
+5. Navigate to project directory:
+    ```commandline
+    cd dlt-meta
+    ```
+
+6. Set python environment variable into terminal:
+    ```commandline
+    dlt_meta_home=$(pwd)
+    export PYTHONPATH=$dlt_meta_home
+    ```
+
+7. Generate DAB resources and set up schemas:
+    This command will:
+    - Generate DAB configuration files
+    - Create DLT-Meta schemas
+    - Upload necessary files to volumes
+    ```commandline
+    python demo/generate_dabs_resources.py --source=cloudfiles --uc_catalog_name=<your_catalog_name> --profile=<your_profile>
+    ```
+    > Note: If you don't specify `--profile`, you'll be prompted for your Databricks workspace URL and access token.
+
+8. Deploy and run the DAB bundle:
+    - Navigate to the DAB directory:
+    ```commandline
+    cd demo/dabs
+    ```
+
+    - Validate the bundle configuration:
+    ```commandline
+    databricks bundle validate --profile=<your_profile>
+    ```
+
+    - Deploy the bundle to dev environment:
+    ```commandline
+    databricks bundle deploy --target dev --profile=<your_profile>
+    ```
+
+    - Run the onboarding job:
+    ```commandline
+    databricks bundle run onboard_people -t dev --profile=<your_profile>
+    ```
+
+    - Execute the pipelines:
+    ```commandline
+    databricks bundle run execute_pipelines_people -t dev --profile=<your_profile>
+    ```
