+## Kubeflow Pipelines Backend and TFX compatibility
+
+Pipelines written in any version of [TensorFlow Extended (TFX)](https://www.tensorflow.org/tfx) will execute on any version of Kubeflow Pipelines (KFP) backend. However, some UI features may not be functioning properly if the TFX and Kubeflow Pipelines Backend versions are not compatible.
+
+The following table shows UI feature compatibility for TFX and Kubeflow Pipelines Backend versions:
+
+| [TFX] \ [KFP Backend] | [KFP Backend] <= 1.5                              | [KFP Backend] >= 1.7                           |
+| --------------------- | ------------------------------------------------- | ---------------------------------------------- |
+| [TFX] <= 0.28.0       | Fully Compatible  ✅                              | Metadata UI not compatible<sup>[2](#fn2)</sup> |
+| [TFX] 0.29.0, 0.30.0  | Visualizations not compatible<sup>[1](#fn1)</sup> | Metadata UI not compatible<sup>[2](#fn2)</sup> |
+| [TFX] 1.0.0           | Metadata UI not compatible<sup>[2](#fn2)</sup>    | Metadata UI not compatible<sup>[2](#fn2)</sup> |
+| [TFX] >= 1.2.0        | Metadata UI not compatible<sup>[2](#fn2)</sup>    | Fully Compatible  ✅                           |
+
+Detailed explanations:
+
+<a name="fn1">1.</a> **Visualizations not compatible**: Kubeflow Pipelines UI and TFDV, TFMA visualizations is not compatible. Visualizations throw an error in Kubeflow Pipelines UI.
+
+<a name="fn2">2.</a> **Metadata UI not compatible**: Kubeflow Pipelines UI and TFX recorded ML Metadata is not compatible. ML Metadata tab in run details page shows error message "Corresponding ML Metadata not found". As a result, visualizations based on ML Metadata do not show up in visualizations tab either.
