 Development must always begin in a local environment. This allows developers to rapidly iterate, test business logic, and validate DAG (Directed Acyclic Graph) structures without impacting production data.
 
 ### 2.1 Project Layout
-To ensure compatibility with the Simpl-Open platform, every Dagster code location must adhere to the following directory structure:
+This repository (`template-code-location`) serves as the **single consolidated code location** for all data services workflows. It contains the jobs, ops, and configurations previously spread across `data-processing`, `dataframe-level-anonymisation`, and `field-level-pseudo-anonymisation`.
