-Originally from https://huggingface.co/datasets/HuggingFaceFW/fineweb, source code at https://github.com/mesolitica/malaysian-dataset/tree/master/corpus/fineweb
+## What is it?
+
+We filter the original 🍷 FineWeb dataset that consists more than **15T tokens** on simple Malaysian keywords.
+
+Total tokens for the filtered dataset is 174102784199 tokens, **174B tokens**.
+
+## How we do it?
+
+1. We filter rows using `{'malay', 'malaysia', 'melayu', 'bursa', 'ringgit'}` keywords on r5.16xlarge EC2 instance for 7 days.
+2. We calculate total tokens using `tiktoken.encoding_for_model("gpt2")` on c7a.24xlarge EC2 instance for 1 hour.
+
