this, but now we have it all.

+#### Aside: re-using blueprint files from other SDKs
+
+While the blueprint APIs are currently only available in Python, blueprints can be saved and re-logged as needed from any language our SDKs support.
+
+First, save the blueprint to a file (`.rbl` by convention) using either the viewer (`Menu > Save blueprint`) or the python API:
+
+snippet: reference/dataframe_save_blueprint
+
+Then log that blueprint file in addition to the data itself:
+
+snippet: reference/dataframe_view_query_external
+
+Check out the blueprint API and `log_file_from_path` references to learn more:
 * [🐍 Python blueprint API reference](https://ref.rerun.io/docs/python/latest/common/blueprint_apis/)
+* [🐍 Python `log_file_from_path`](https://ref.rerun.io/docs/python/latest/common/logging_functions/#rerun.log_file_from_path)
+* [🦀 Rust `log_file_from_path`](https://docs.rs/rerun/latest/rerun/struct.RecordingStream.html#method.log_file_from_path)
+* [🌊 C++ `log_file_from_path`](https://ref.rerun.io/docs/cpp/stable/classrerun_1_1RecordingStream.html#a20798d7ea74cce5c8174e5cacd0a2c47)
 
 
 ### Setting up dataframe view manually in the UI
 
-TODO(cmc): incoming.
+The same [dataframe view](types/views/dataframe_view) shown above can be configured purely from the UI:
