+### ❗IMPORTANT❗: Escaping special characters
+
+Values in columns `prompt`, `think_process`, and `solution` have escaped special characters like `\n`, `\t`, and `\\`!
+
+The reason for this behavior: the Python's `csv` module that I'm using in the parser to save rows saves `\n` as an actual newline character, 
+which makes reading the prepared file with Pandas impossible.
+
+To fix it use simple lambda code:
+```python
+return_back_special_symbols = lambda x: x.replace("\\n", "\n").replace("\\t", "\t").replace("\\\\", "\\")
+```
