> - We're excited to share a new multiple interface QIIME 2 tutorial, the [Cancer Microbiome Intervention](https://docs.qiime2.org/jupyterbooks/cancer-microbiome-intervention-tutorial/) tutorial. This tutorial derives from data from over 12,000 human-cancer-associated microbiome samples published in 2021 in [_Compilation of longitudinal microbiota data and hospitalome from hematopoietic cell transplantation patients_](https://www.nature.com/articles/s41597-021-00860-8). Users can choose whether to follow along using the QIIME 2 Galaxy Interface (which you can learn how to install [here](https://youtu.be/sdmhnKPR7G8)), the QIIME 2 command line interface, or the Python 3 API. This content is provided as a [JupyterBook](https://jupyterbook.org/intro.html), a documentation tool that you can expect to see a lot more of around the QIIME 2 ecosystem. 🧐
> - [A new, free QIIME 2 YouTube course](https://youtube.com/playlist?list=PLbVDKwGpb3XmvnTrU40zHRT7NZWWVNUpt) that parallels the Cancer Microbiome Intervention tutorial. Over the next several months, we'll release new videos each week. This is our first video tutorial series that focused on the Galaxy interface, so if you want to learn to use QIIME 2 through Galaxy, this is a great place to start! @gregcaporaso provides a 3.5 minute introduction to the course [here](https://youtu.be/iqz1c2QhUD8). ▶
> - @gregcaporaso is sharing a preview of his QIIME 2 JupyterBook, [q2book](https://gregcaporaso.github.io/q2book/front-matter/preface.html). This is a work-in-progress, and not yet complete, but you can find useful background on [QIIME 2 archives (i.e., .qza and .qzv files)](https://gregcaporaso.github.io/q2book/using/getting-started.html#qiime-2-archives), [semantic types](https://gregcaporaso.github.io/q2book/using/getting-started.html#semantic-types-data-types-and-file-formats), [importing](https://gregcaporaso.github.io/q2book/using/importing.html), and more topics that will help you deepen your understanding of how QIIME 2 works and why. 📔
> - Our Jupyter Book based tutorials (mentioned above), can be found on a new page in our user documentation, titled [_Jupyter Book Tutorials_](https://docs.qiime2.org/2022.2/jupyter-book-tutorials/). 📚📙📚
