   - For the *Pupil Core*, for best results you may wish to do a scene camera calibration yourself, see https://docs.pupil-labs.com/core/software/pupil-capture/#camera-intrinsics-estimation.
     If you do not do so, a generic calibration will be used by Pupil Capture during data recording, by Pupil Player during data
     analysis and by the glassesTools processing functions, which may result in incorrect accuracy values.
+- *Meta Project Aria Generation 1*:
+  - First, open a recording in Aria Studio on the computer.
+  - In Aria Studio, request a MPS run for eye gaze (if you haven't already done so), and wait for it to complete successfully.
+  - Open the [`meta_aria_gen1_exporter.py`](https://github.com/dcnieho/glassesTools/tree/master/tools/meta_aria_gen1_exporter.py) script
+    provided in glassesTools and set the variable `vrs_file` to the full path to the recording's `.vrs` file. By default, it is assumed
+    that the recording's `.vrs` file and the MPS results are in the same folder and have the default names used by Aria Studio, e.g.
+    `some_folder/recording.vrs` and `somefolder/mps_recording_vrs`. If the MPS results are located elsewhere, you can provide the
+    path to them using the `mps_folder` variable (optional).
+  - Run the script (ensure you have the right packages installed, see the comment atop the script). An export of the recording will
+    be made in a format that can be imported by gazeMapper and by default stored in the folder `somefolder/export_recording`. If you
+    wish to use another export folder, set the variable `output_folder` (optional).
 - *SMI ETG*: For SMI ETG recordings, access to BeGaze is required and the following steps should be performed:
   - Export gaze data: `Export` -> `Legacy: Export Raw Data to File`.
     - In the `General` tab, make sure you select the following:
