+# {{.project_name}}
+
+The '{{.project_name}}' project was generated by using the default-dlt template.
+
+## Getting started
+
+1. Install the DLT CLI
+
+2. Authenticate to your Databricks workspace, if you have not done so already:
+    ```
+    $ dlt login
+    ```
+
+3. Edit the transformations for your DLT code under transformations/!
+
+4. To run your DLT code, type
+    ```
+    $ dlt run
+    ```
+
+5. To do a "dry run" to validate correctness of your DLT code, type
+    ```
+    $ dlt dry-run
+    ```
+
+6. To inspect your DLT pipeline in a browser, type
+   ```
+   $ dlt open
+   ```
+
+7. That's all you need to get started! Please reference the [DLT documentation](https://docs.databricks.com/delta-live-tables/)
+   to learn more about DLT and about how this project can be configured.
