 ## Credits
 
-The human-checked lines in the Georgian-based alphabet are the work of **Marat Ionov**: his
-[*Abkhaz Mkhedruli Dataset for PaddleOCR*](https://huggingface.co/datasets/Grundik/abkhaz-mkhedruli-dataset-paddle),
-built in collaboration with the Bagrat Shinkuba Foundation from apsnyteka.org scans and published
-under CC BY-NC-SA 4.0. Two parts of it are used here:
-
-- **training** — 2,780 real line images from 12 of his source books (`ionov-train`, images under
-  `data/ionov-mkhedruli/`, each used three times per epoch);
-- **testing** — the lines from his other 6 books, which are also books in our own test set, were
-  kept out of training; they are the human-checked test in the results table below.
-
-His lines are the sharpest measure we have of how well the reader reads the Georgian-based alphabet.
+Human-checked lines in the Georgian-based alphabet come from **Marat Ionov**'s
+[*Abkhaz Mkhedruli Dataset for PaddleOCR*](https://huggingface.co/datasets/Grundik/abkhaz-mkhedruli-dataset-paddle)
+(made with the Bagrat Shinkuba Foundation; CC BY-NC-SA 4.0). They are used in two ways: lines from
+12 of his source books are in the training set (`ionov-train`), and the lines from his other 6
+books were kept out of training and are the human-checked test in the results below.
