-# Dataset Card for "code_tutorials"
+# Coding Tutorials
 
-1.5 billion tokens
+This comprehensive dataset consists of **500,000** documents, summing up to around **1.5 billion** tokens. 
+Predominantly composed of coding tutorials, it has been meticulously compiled from various web crawl datasets like **RefinedWeb**, **OSCAR**, and **Escorpius**.
+The selection process involved a stringent filtering of files using regular expressions to ensure the inclusion of content that contains programming code (most of them).
 
-### Programing language distribution
+These tutorials offer more than mere code snippets.
+They provide an extensive context, including the rationale behind the code, the problem being addressed, and detailed step-by-step instructions. 
+This layered context is helpful for training a code-LM model, enabling it to discern the user intent behind a piece of code and thus facilitating more contextually relevant assistance.
