+## Display settings
+
+* Clone the primary display to the slave monitor.
+* Display resolution - 1920 x 1080, refresh rate - 60 Hz.
+
+## How to run
+
+* Download the audio files (`.wav` files with suffix `task-lppFR`) from OpenNeuro: https://openneuro.org/datasets/ds003643/versions/2.0.1
+* Print the `protocol/questions_reponses_a_imprimer.pdf` file to mark participant's answers after each run
+* Go into the task folder:
+	
+	```
+	$ cd le_petit_prince/protocol
+	```
+
+### Practice
+
+* No practice
+
+### Scanner task
+
+* Run the script `run-lepetitprince-mri.sh` as follows:
+	
+	```
+	$ sh run-lepetitprince-mri.sh
+	```
+
+* Select the run and press Enter.
+
+* Ask the questions after each run and mark the answers on the printed sheet. Open the file `questions_a_presenter.pdf` for the participant with the command shown, eg.:
+
+	```
+    $ evince -s -p 4 questions_a_presenter.pdf
+	```
+
+* This would open the pdf at page 4 after run 1 and similarly, prompts after each run show corresponding page number in the pdf.
+
+## How to quit
+
+Don't. (`Ctrl + C` in emergency)
+
+## Responses
+
+* No responses except for the verbal ones after each acquisition run
+
+## Design
+
+* 2 sessions
+* 5 runs (session 1) + 4 runs and 1 localizer (session 2)
+
+## Software info
+
+* Python 3.8.5, Expyriment 0.10.0.
+* Primary script `run-lepetitprince-mri.sh`
+* Secondary scripts `lepp_mri.py` for runs 1-9 and `localizer/localizer-speech.py` for the localizer.
+
+## Other info
+
+* Specified paths and scripts were originally run and tested on Ubuntu OS, so might need mods for running on Windows OS.
+* `instructions_for_participants` contain original instructions in French and their English translations (from Google Translate) with `EN_` prefix
+* same goes for `protocol/questions_reponses_a_imprimer.pdf` and `protocol/questions_a_presenter.pdf`
