**q2-sourmash** is an implementation of [sourmash](https://sourmash.readthedocs.io/en/latest/), a Python library for computing and comparing MinHash sketches from DNA sequences. This allows for the similarity between large datasets to be estimated quickly and accurately.

To read more about sourmash checkout the documentation for the [Python library] ([Welcome to sourmash! — sourmash 4.8.13.dev0 documentation](https://sourmash.readthedocs.io/en/latest/)) or the [the paper](http://joss.theoj.org/papers/10.21105/joss.00027).

For details on the QIIME2 implementation of sourmash (q2-sourmash), including installation and usage information, please see the Github repository: [GitHub - dib-lab/q2-sourmash: Qiime2 Sourmash Plugin](https://github.com/dib-lab/q2-sourmash).
