+### Dataset Summary
+
+EusCrawl (http://www.ixa.eus/euscrawl/) is a high-quality corpus for
+Basque comprising 12.5 million documents and 423 million tokens,
+totalling 2.1 GiB of uncompressed text. EusCrawl was built using
+ad-hoc scrapers to extract text from 33 Basque websites with
+high-quality content, resulting in cleaner text compared to general
+purpose approaches.
+
+### Supported Tasks and Leaderboards
+
+EusCrawlis intended for pretarining models for language modeling or masked language modeling.
+
+### Languages
+
