# Dataset Card for ZelaiHandi🌱

<!-- Provide a quick summary of the dataset. -->
ZelaiHandi🌱: A Large Collection of Basque Texts. 
ZelaiHandi, which means "large pasture" in Basque, is the largest collection of freely licensed and clean Basque texts to date (March 4th, 2024), gathered from selected web sources.
This collection comprises approximately 521 million tokens.

The dataset will receive periodical updates.

The corpus has been released with the objective of “feeding” Large Language Models. Naturally, models that are not strictly "herbivorous" can also ingest ZelaiHandi.
