-Over the past three years, the Executable Books team has focused its efforts on building a Sphinx-based technical stack underlying the Jupyter Book project. This has been extremely successful, and Jupyter Book and the associated MyST ecosystem in Sphinx have gained adoption across both scientific and open source communities. The MyST Parser for Sphinx averages around 350,000 downloads a month, which makes up about 13% of all Sphinx downloads ([https://www.pepy.tech/projects/myst-parser?versions=*](https://www.pepy.tech/projects/myst-parser?versions=*)). There are over 4000 Jupyter Book’s in public GitHub repositories ([https://github.com/search?q=%22format%3A+jb-book%22&type=code](https://github.com/search?q=%22format%3A+jb-book%22&type=code)), many of which are now featured at [gallery.executablebooks.org](https://executablebooks.org/en/latest/gallery/).

 **Developer community growth.** Finally, Angus will work with other Steering Council and project members to lay a foundation for the Executable Books _organization_ moving forward, including identifying a fiscal home for the project and developing our initial contributing policies and guidelines as we begin opening up the project for formal participation from the broader community.
 
-We hope that this gives a picture of the progress that we’ve made in the last few years, where our project stands now, and where we are deploying the final resources of our grant in pursuit of our goals to create open tools for communicating computational narratives. We’re excited to have Rowan and Angus joining the team in a formal capacity, and look forward to the great work that they’ll do.
