 ### Other project metrics
 
 TODO(#6161): Collect metrics for miscellaneous IREE system states
+
+## Developer notes
+
+These are ad-hoc notes added for developers to help triage errors.
+
+### Repro of TFLite model errors
+
+These steps help reproduce the failures in TFLite models. 
+
+1.  Install `iree-import-tflite`.
+    ```
+    $ python -m pip install iree-tools-tflite-snapshot -f https://github.com/google/iree/releases
+    ```
+
+2. Confirm the binary `iree-import-tflite` is in your path by running
+    ```
+    $ iree-import-tflite --help
+    ```
+
+3. Download the TFLite flatbuffer for the failing benchmarks. The
+location can be found from [this CMakeLists.txt file](./TFLite/CMakeLists.txt)
+
+4. The input TOSA model can be generated by running
+    ```
+    $ iree-import-tflite <tflite file> -o <tosa output file>
+    ```
+
+5. The exact flags used to compile and run the benchmarks can be
+found in [this CMakeLists.txt file](./TFLite/CMakeLists.txt)
