+# Plaintext questions with IRT estimations on all Interactions
+
+This directory contains question and answer text, as well as IRT data that was calculated on all available interactions - Instead of only on pretests, as the INEP data does AFAICT - at [enem.csv](./enem.csv).
+
+A template can be found at [enem.template.csv](./enem.template.csv).
+
+More information about the format may be added at a later point, or may be found in the project code.
+Sorry.

+# HFT Data
+The directory containing the raw data of the HFT dataset.
+As the dataset is private this is mostly here as reference, with some README.md files explaining how it should look like.
+
+# Files
+
+## `experimental_data_extract.csv`
+
+Refer to the [template](./experimental_data_extract.template.csv).
+Explanations of the rows below.
+
+### Row explanations
+
+title: string: Title of the question, corresponds to the name in moodle xml export
+#quiz_participants: Natural number: number of participants in the quiz containing this question that generated the `part_total_points`
+mean_share_total_points: float in [0,1]: mean share of the total points that can be reached
+lecture: string: the module this question corresponds to (you can choose the identifier, be sure to add the lectures in the code thats handling all this.).
+retries_allowed: boolean: Whether it was possible to do the quiz this question was asked in multiple times in one go
+
+## `[lecture]` subdirs
+
+Create a subdirectory for each `lecture` referred to in [the experimental_data_extract.csv file above](#experimental_data_extractcsv).
+Each subdir must contain a `quiz.moodle.xml` file, which is an xml export from Moodle.
+
+Please refer to the official documentation as well as the reading code in this project, to get an idea how that XML looks like.
