+   ```bash
+   go version
+   ```
+
+3. Install dependencies:
+   ```bash
+   go mod tidy
+   ```
+
+### Code Formatting
+Ensure your code adheres to the repository's formatting guidelines before committing. You can use the following command to format the code:
+```bash
+go fmt ./...
+```
+
+### Environment Setup
+To run integration tests or interact with the Atlan API, you'll need to configure your environment:

+    - For Windows (PowerShell):
+      ```powershell
+      Get-Content .env | ForEach-Object {
+          if ($_ -match '^(.*?)=(.*)$') {
+              $env:($matches[1]) = $matches[2]
+          }
+      }
+      ```
+
