 # The challenge
 
-We ask you to classify the sequences (see dataset) using your pipeline
-and send us your results. The classification will be evaluated using
-the Taxonomy Release [MSL39](https://ictv.global/news/taxonomy_2023
-"MSL39"). Importantly, we ask that your pipeline be <b>fully
-reproducible</b> and that you make available the necessary code and
-environment to run it. Multiple strategies exist, such as the creation
-of virtual environments (venv, conda) or containers (Singularity,
-Docker), and the pipeline should be made available via a git
-repository (Github, Bitbucket). The results of your classification
-will be further evaluated on metrics including reproducability, speed,
-accuracy at different ranks, for different types of viruses, etc.
