-This is a dummy ML-pipeline
+This is a dummy ML-pipeline, consisting of:
+- dvc tracking for version control (data and models)
+- gto for model registry
+- docs, created via sphinx (in pre-commit hooks)
+- tests for unit, integration and end to end testing
+
+Within `src` folder, the structure is as follows:
+- multiple pipelines can be defined
+    - i.e. for a product, we might require multuple pipelines do deliver a result
+    - i.e. multiple models
+- these models can be all tracked within the same gto model registry
