Read the Docs generates a lot of data. We are the largest documentation platform out there, with hundreds of thousands of projects using our product every day to host their documentation. This data includes simple things like number of users, builds using a particular Docker image, as well as more interesting ones like pageviews or Python dependencies installed via a requirements.txt file. We didn’t collect this data in a systemic way during the first 10 years of our existence.

Last year, with the growth of our product and the team, plus the CZI grant we received, we started asking ourselves some questions that we couldn’t answer with the data we had. We decided to start working on a project to collect relevant data to answer a large number of questions about how people use our service.

We are thrilled to announce the availability of Read the Docs Embed API v3, along with its official client, sphinx-hoverxref 1.0. This work has been possible in part thanks to the the CZI grant we received.

As we wrote in our first blog post about sphinx-hoverxref, one of the most powerful features of Sphinx is the possibility of creating cross references to other documentation projects. However, a reader finding several links in a technical documentation might need to open several browser tabs to fully understand the context, resulting in a lot of friction in the form of context switching.

We have released version 0.6b1 of sphinx-hoverxref, a Sphinx extension that shows a content preview of a cross-reference.

This extension is an essential part of the work we are doing to improve interoperability of documentation in general, and scientific documentation in particular, thanks to the CZI grant we received last year.

We’re excited to announce that Read the Docs has received a $200,000 grant from the Chan Zuckerberg Initiative’s Essential Open Source for Science (EOSS) program. Read the Docs is the largest open source documentation hosting platform in the world. We provide hosting for many scientific software packages, including some that have received EOSS funding in the past. You can read more about this round of grants in the official announcement.
