+### Setup
+
+This integration pulls metadata directly from Cassandra databases, including both **DataStax Astra DB** and **Cassandra Enterprise Edition (EE)**. 
+
+You’ll need to have a Cassandra instance or an Astra DB setup with appropriate access permissions.
+
+#### Steps to Get the Required Information
+
+1. **Set Up User Credentials**:
+
+   - **For Astra DB**:
+     - Log in to your Astra DB Console.
+     - Navigate to **Organization Settings** > **Token Management**.
+     - Generate an **Application Token** with the required permissions for read access.
+     - Download the **Secure Connect Bundle** from the Astra DB Console.
+   - **For Cassandra EE**:
+     - Ensure you have a **username** and **password** with read access to the necessary keyspaces.
+
+2. **Permissions**:
+
+   - The user or token must have `SELECT` permissions that allow it to:
+     - Access metadata in system keyspaces (e.g., `system_schema`) to retrieve information about keyspaces, tables, columns, and views.
+     - Perform `SELECT` operations on the data tables if data profiling is enabled.
+
+3. **Verify Database Access**:
+   - For Astra DB: Ensure the **Secure Connect Bundle** is used and configured correctly.
+   - For Cassandra Opensource: Ensure the **contact point** and **port** are accessible.
+
+
+:::caution 
+
+When enabling profiling, make sure to set a limit on the number of rows to sample. Profiling large tables without a limit may lead to excessive resource consumption and slow performance.
+
+:::
+
+:::note
+
+For cloud configuration with Astra DB, it is necessary to specify the Secure Connect Bundle path in the configuration. For that reason, use the CLI to ingest metadata into DataHub.
