+`MIRACL <https://project-miracl.github.io/>`_ (Multilingual Information Retrieval Across a Continuum of Languages) 
+is an WSDM 2023 Cup challenge that focuses on search across 18 different languages.
+They release a multilingual retrieval dataset containing the train and dev set for 16 "known languages" and only dev set for 2 "surprise languages".
+The topics are generated by native speakers of each language, who also label the relevance between the topics and a given document list.
+You can found the `dataset <https://huggingface.co/datasets/miracl/miracl-corpus>`_ on HuggingFace.
+
+You can evaluate model's performance on MIRACL simply by running our provided shell script:
+
+.. code:: bash
+
+    chmod +x /examples/evaluation/miracl/eval_miracl.sh
